Or is a demo source available using screen? Thanks, Mario mario sangalli 2023-10-16T07:52:31Z http://community.qnx.com/sf/go/post121656 I am newly started working on QNX environment. I want to build a sample c/c++ QNX OpenCV application to run on “aarch64le”. I am using Jacinto 7 board in which QNX is running on a72 core and QNX SDP Version 7.1. Please help me to build sample opencv application to run on QNX.

I am working on getting QNX neutrino 7.0 with vmware graphics working on QEMU. I did bit of reading and understood that QNX doesnt support this. Anyone here has any past experience with it. Any leads would be helpful. Thnx Anandu S(deleted) 2021-10-22T08:37:47Z http://community.qnx.com/sf/go/post121574 Hi I've installed QNX 6.5 on Advantech UNO-2272G-J2AE with Intel Celeron Quad Core J1900 (Graphic Engine: Intel HD Graphic). What graphics driver should I use? I've tried devg-intelhd.so and devg-i830.so but they don't work. Only vesabios and svga are working. Best regards Waldi KOMSTER Ltd. 2021-08-31T09:29:23Z http://community.qnx.com/sf/go/post121550 I am using the SCREEN_PROPERTY_MODE property (screen_get_display_property_pv) to set/change the graphics mode. These mode changes have an impact on graphics output and display synchronization, so it is important to know when the mode change has been fully applied. However, the method for doing this is not clear. Mode change time seems to vary drastically, taking 250ms one time and over 1.5 seconds the next. Mode change time can be seen from monitoring screen slog information as well as looking at the display. I read the mode properly after setting (which flushes the command), but it returns the new mode even though that mode is not yet applied. I tried an explicit flush command, but that had no impact. I also tried "wait_vsync", to no effect. david lavacek 2021-08-02T16:15:39Z http://community.qnx.com/sf/go/post119804 Hi In my case, I want to encode a pixel buffer into a piece of memory in png format.I just write the code: BYTE* pbtBuffer = new BYTE[img.w * img.h]; s_writeBufferSize = img.w * img.h; io_stream_t* pOutStream = io_open( IO_MEM, IO_WRITE, img.w * img.h, pbtBuffer ); if ( !pOutStream ) { CLogApp::info( String::format( L"io_open error: %d", errno ) ); return FALSE; } pOutStream->output.write_f = ioMemoryWrite; But I cannot do io_open( IO_MEM...) with IO_WRITE. I search the history and find that qnx not support the write mode with io_mem. How can I do this. Can someone help me? Thanks!!!!!!!!!!!! Deng Daokuan(deleted) 2019-08-13T07:06:39Z http://community.qnx.com/sf/go/post119693 Hello, I am using the generic Intel x86_64 BSP on a Dell computer with an Intel i3 Skylake processor with standard integrated graphics. Will Screen run on such a machine and is there a Screen configuration available that I can try? The BSP that I am using appears to provide a screen configuration for the Intel NUC only. Thanks, John John Efstathiades 2019-05-06T06:48:11Z http://community.qnx.com/sf/go/post119447 never mind, use legacy driver "devi" instead of "hid" solve the problem. Mike mike scott(deleted) 2019-01-24T11:01:46Z http://community.qnx.com/sf/go/post119434 another issue, after the first unsuccessful "accept"ed calibration, I tried to do recalibration with calib-touch -zorder=20 -config-file=/tmp/calib.localhost -recalibrate this time stuck at Figure 1 of http://www.qnx.com/developers/docs/6.6.0_anm11_wf10/#com.qnx.doc.neutrino.utilities/topic/c/calib-touch.html i.e., the target never moves no matter touch any place on the whole screen. It seems, the previous calibrated data were still in use, and blocked the recalibration. Please advise, thanks in advance. Mike mike scott(deleted) 2019-01-22T13:35:29Z http://community.qnx.com/sf/go/post119431 Hi QNX, qnx sdp 6.6, qnx sdk for apps and media 1.1 release, BSP_ti-am335x-beaglebone_br-660_be-660_SVN797070_JBN574.zip beaglebonedemo.ext.anm11.258.150325_2017 touchscreen 800x480 I am working on touchscreen with beaglebone black on qnx 6.6. Touchscreen starts with calib-touch 3-point calibration. However it stuck at the last step as described in Figure 4, http://www.qnx.com/developers/docs/6.6.0_anm11_wf10/#com.qnx.doc.neutrino.utilities/topic/c/calib-touch.html exactly same situation as previous post, "calib-touch program doesn't accept or recognize that." http://community.qnx.com/sf/discussion/do/listPosts/projects.graphics/discussion.advanced_graphics.topc25633 After many times tries, calib-touch finally "accept" and save the data to calib.localhost. However, the calibration is not accurately at all. You have to estimate and try to figure out exact location, for example, in QT keyboard demo program from beaglebonedemo, push "2" maybe come out "8", very frustrating. Please advise, thanks in advance Mike mike scott(deleted) 2019-01-22T12:30:57Z http://community.qnx.com/sf/go/post119307 Hi, I want to show YUV image on the RGB display panel through the APIs of Screen, but I can not work ok, could you please provide me some demos for it? The development environments are follow: 1. QNX6.6.0 2. i.MX6DL 3. Screen 4. dual lvds display pannel(1920*720) 5. NV12 images Best regards, Gary Li Chunmei(deleted) 2018-11-27T01:32:54Z http://community.qnx.com/sf/go/post118575 Alright, thank you. I'll ignore those error messages then. Benedikt Franz(deleted) 2018-02-14T09:23:19Z http://community.qnx.com/sf/go/post118573 It's an artifact of the Vivante porting layer and can be ignored (as long as there is no file named 'glesv2-sc-dlls' in LD_LIBRARY_PATH). Zygo Blaxell 2018-02-13T17:06:44Z http://community.qnx.com/sf/go/post118564 Dear community, I have an i.MX6 quad based system running QNX6.6.0. While deploying Qt5, I noticed something a bit odd. When starting some of the example apps which came with the build, some of them would give me an error message (with LD_DEBUG=libs, the app does still start up despite the error): libs: load_object: attempt load of glesv2-sc-dlls.so libs: dlopen: Library cannot be found libs: dlopen("/usr/lib/graphics/iMX6X/libGLSLC.so",1536) Mode: LOCAL GROUP I've attached a full dump. Someone in a different post suggested it might be of no relevance but I would like to be sure. I've also attached our graphics.conf - maybe I configured the glesv2-sc-dlls section wrong - the libSLSLC.so does exist, and is located in /usr/lib/graphics/iMX6X, executable. I get the error message for gles2-gears (although as stated above, it runs fine) and also for a few Qt example apps which use gles2. Any thoughts on whether or not this error message is actually relevant? Benedikt Franz(deleted) 2018-02-13T08:10:58Z http://community.qnx.com/sf/go/post118257 Thank you for fast response. I would like to do it myself. In particular - how to properly initialize struct _io_bstream { io_stream_t stream; unsigned flags; _uint8 *buf; unsigned bufsiz, buf_pos, buf_nleft; unsigned pos, nleft; io_close_f *close_f; } in my version of "io_open_f()"? I have tried but it does not work properly (perhaps flags or sizes not set properly). Is there doc or example? Andrzej Polanski 2017-12-01T15:40:41Z http://community.qnx.com/sf/go/post118256 No, it is a read-only interface.

Thank you very much! andrew huang(deleted) 2017-05-27T07:58:59Z http://community.qnx.com/sf/go/post117358 I'm creating a graphics application to run on i.MX6 Sabre SDB and I’m running into a SIGSEGV fault when I call ‘vgCreateEGLImageTargetKHR’ API. Can someone please help me figure out the root cause for this? I’m trying to use the EGL_KHR_image extension as a means to share images between the OpenGLES2 and OpenVG rendering APIs. So, I wrote some code to create an EGLImageKHR type as shown below. After successful creation of the EGLImageKHR, I was able to create an OpenGLES2 texture using the EGL image (glEGLImageTargetTexture2DOES ) and render it to the display. But, I see a SIGSEGV fault, when I attempt to create an OpenVG texture using the same EGL Image. The OpenVG extension function that I’m using is - vgCreateEGLImageTargetKHR void * driver_CreateEglImageBuffer(EGL_DDB *pDdb) { int size[2] = {pDdb->width, pDdb->height}; int format = SCREEN_FORMAT_RGBA8888; void * ret_buffer = NULL; int result; /* Create a pixmap buffer. This buffer will be used to hold the ** bitmap and eventually create an eglImage. */ result = screen_create_pixmap((screen_pixmap_t *)&(pDdb->pixmap.pixmapId), egl_layer->win.screen_ctx); if (result == 0) { int usage = SCREEN_USAGE_OPENGL_ES2 | SCREEN_USAGE_OPENVG; screen_buffer_t screen_pbuf; screen_set_pixmap_property_iv(pDdb->pixmap.pixmapId, SCREEN_PROPERTY_USAGE, &usage); screen_set_pixmap_property_iv(pDdb->pixmap.pixmapId, SCREEN_PROPERTY_FORMAT, &format); screen_set_pixmap_property_iv(pDdb->pixmap.pixmapId, SCREEN_PROPERTY_BUFFER_SIZE, size); result = screen_create_pixmap_buffer(pDdb->pixmap.pixmapId); if (result != 0) { screen_destroy_pixmap(pDdb->pixmap.pixmapId); printf("Fail! screen_create_pixmap_buffer() returned %d\n", result); } else { screen_get_pixmap_property_pv(pDdb->pixmap.pixmapId, SCREEN_PROPERTY_RENDER_BUFFERS, (void**)&screen_pbuf); /* Get the buffer pointer */ screen_get_buffer_property_pv(screen_pbuf, SCREEN_PROPERTY_POINTER, (void**)&pDdb->pixmap.pixmapBuffer); /* Get the buffer stride */ screen_get_buffer_property_iv(screen_pbuf, SCREEN_PROPERTY_STRIDE, (int *)&(pDdb->stride)); /* Create EGL Image */ pDdb->pixmap.eglImage = eglCreateImageKHR(egl_layer->win.eglDisplay, EGL_NO_CONTEXT, EGL_NATIVE_PIXMAP_KHR, (void *)pDdb->pixmap.pixmapId, NULL); if (pDdb->pixmap.eglImage == EGL_NO_IMAGE_KHR) { EGLint eglError = eglGetError(); if (eglError != EGL_SUCCESS) { printf("eglGetError() = %i\n", eglError); } } else { ret_buffer = pDdb->pixmap.pixmapBuffer; } } } return ret_buffer; } Saleem Shaik 2017-01-20T17:29:53Z http://community.qnx.com/sf/go/post117323 All right, thanks all the same. > Yes, please ask your FAE to contact support directly on your behalf. > > Regards, > Derek > > -----Original Message----- > From: yang lei [mailto:community-noreply@qnx.com] > Sent: Monday, January 9, 2017 3:29 AM > To: advanced-graphics <advanced-graphics@community.qnx.com> > Subject: Re: RE: How to get wfdcfg source code(LCD) for I.MX6q-sabre-smart- > devices board > > Hi, Derek > Thanks for your reply, but my FAE told me that use the standard support > plan.

I'm using QNX 6.4.1 on i.MX515 with 320x240 16 bit display and I have a problem with performance: 1. A simple loop drawing (gf_draw_rect()) one white rectangle on the whole screen at 30fps uses 26% of CPU. 2. vsync demo uses 66% of CPU 3. egl-gears uses 80% of CPU My guess is that the software is not using hardware acceleration. I have been searching for more info about it, but can't find anything useful. What I keep finding is the sentence “(...) using hardware acceleration where possible”, but I have no idea how to make it possible. The answer is probably simple enough to not put it in tutorials, but apparently I don't have enough knowledge in that topic and I don't even know where to look for it. Could anyone point me in the right direction, please?

The application would run on ARM processor. The application would have to access the Video memory, to check the contents of the display, in order to set and read any random pixel, also make sure the display is not frozen, etc. I see that the services provided by Video BIOS services are what I need (e.g. vbios _ int(), vbios _ register(), etc), but these services are available only for x86 and not for ARM. My question is, are there any equivalent services that I could use for ARM? Thanks in advance.

I'd like to use these same buffers for screen and just post them when they are filled. The attached code snippet outlines the basics of my approach, but it isn't working. To illustrate and try to figure this out I'm using the sync tutorial. You'll see the #ifdef clause that contains the code I would like to execute and have it work. The result of the #ifdef block is a blank screen. Of course, using the original code works. Basically I would like to allocate the memory and assign it to a screen buffer and have screen use that memory instead of its own allocation. Docs suggest that this is known and supported method, but apparently I'm missing some detail. Kevin Stallard 2015-01-31T01:17:34Z http://community.qnx.com/sf/go/post113140 OK, thank you very much!

Viktor Lezhava(deleted) 2015-01-29T14:18:01Z http://community.qnx.com/sf/go/post113137 I'm new to QNX os, any suggested tutorial how to run screen on QNX6.5 will be very helpful. I'm familiarized with: a) Screen Graphics Subsystem Developer's Guide b) OpenWF Display Configuration Developer's Guide Since there is no WFD and Wfdcfg driver src available to me, I have no idea how to write my hardware specific WFD drivers. My processor is TI-AM3517, there is no available binary for me. Would anyone help me on how to write WFD driver? Thank you very much! Somnus ueste(deleted) 2015-01-29T14:04:40Z http://community.qnx.com/sf/go/post113136 Dear Lezhava, I'm new inQNX os and I wanna run screen on QNX6.5. I have read the below articles: a) Screen Graphics Subsystem Developer's Guide b) OpenWF Display Configuration Developer's Guide But I still have no idea how to write WFD driver. Would you please provide your WFD driver src as a sample to me? My email is wangwei_1720@126.com. Thank you very much! Somnus ueste(deleted) 2015-01-29T13:53:45Z http://community.qnx.com/sf/go/post112996 As I understand you trying to show transparent image with gf_splash? To draw image with transparecy this application uses gf_draw_blit2() with configured chroma key. Does your driver supports this feature? Best regards Andrey Andrey Docuchaev 2015-01-19T16:05:56Z http://community.qnx.com/sf/go/post112993 Its the gf_splash application - available in several bsp's. Running on an arm-v7 target. Looks like there might be a possibility for gf_surface_attach to return ok but not deliver a surface opaque pointer. Any idea what (can) cause(s) this behaviour? tia George George Refseth(deleted) 2015-01-19T13:00:52Z http://community.qnx.com/sf/go/post112992 Hello George, What do you mean by "external memory"?

Viktor Lezhava(deleted) 2014-12-17T21:19:38Z http://community.qnx.com/sf/go/post112356 I've changed touch screen controller to HID compliant device. After figuring out what's going on, QNX support guy said that something is different between their egalax touch screen controller and mine. And if I want to go further, I have to pay 10000$ at least for priority support(bronze). Even though it works with QNX 6.5.0. Anyway, now I can touch and move the cursor on the screen but coordinates are not fit. So I've tried to calibrate but result was same as you. The cursor moves, but calib-touch program doesn't accept or recognize that. I'm using a screen with 1024x600. But when I run 'devi-hid' from command line, some suspected output displayed. # devi-hid -vvvvvvv mouse touch ... Did not find calib info for [639x479]. Attempting to use calculated transformation. ... I've set the resolution to 1024x600 through the same way as you and I don't know why that message displayed. As your result is same with me, I wonder what's the output from devi-hid from command line with -vvvvvvv? qnx1 developer(deleted) 2014-11-17T00:38:00Z http://community.qnx.com/sf/go/post112242 Hi, I am also trying to use touch screen with QNX 6.6 on TI Jacinto 6 (DRA74x) EVM (Rev E1) with 7" display. I have used the screen patch and apps & media and run the driver for touch as per the QNX SDP user guide that came along with the BSP. When I run the calib-touch utility, I get the calibration display but my touch inputs don't get registered. I am not able to calibrate. I have added the resolution of LCD I am using (800x480) to /etc/system/config/scaling.conf i.e. 800x480:mode=direct Here is the sloginfo output when I run screen: Jan 01 00:00:15 5 8 300 screen: starting up...

After launching below programs in rc.local, calib-touch program could be run. But touch doesn't work and cannot calibrate. With QNX 6.5 touch screen works fine. Does anyone have any idea what's wrong? Thanks.

I just have an assignment to load and display an image using the image library "libimg" and the "QNX Screen" API. I created my code based on the sample code given in http://support7.qnx.com/download/downlo ... _Guide.pdf, also the sample code given in the post https://github.com/blackberry/NDK-Sampl ... ure/main.c. My code is below (omit all print code for debugging): static img_t img; screen_context_t screen_context; screen_window_t screen_window; int main(int argc, char * const argv[]) { screen_create_context(&screen_context, SCREEN_APPLICATION_CONTEXT); screen_create_window(&screen_window, screen_context); int count = 0; screen_get_context_property_iv(screen_context,SCREEN_PROPERTY_DISPLAY_COUNT, &count); screen_display_t *screen_disps = calloc(count, sizeof(screen_display_t)); screen_get_context_property_pv(screen_context, SCREEN_PROPERTY_DISPLAYS, (void **) screen_disps); screen_display_t screen_disp = screen_disps[0]; free(screen_disps); int vis = 1; int dims[2] = { 512, 512 }; int rect[4] = { 0, 0, 1, 1 }; screen_set_window_property_iv(screen_window, SCREEN_PROPERTY_VISIBLE, &vis); screen_set_window_property_iv(screen_window, SCREEN_PROPERTY_BUFFER_SIZE,rect + 2); rev = screen_set_window_property_iv(screen_window,SCREEN_PROPERTY_SOURCE_SIZE, dims); screen_buffer_t screen_buf; screen_create_window_buffers(screen_window, 1); screen_get_window_property_pv(screen_window, SCREEN_PROPERTY_RENDER_BUFFERS, (void **)&screen_buf); screen_get_buffer_property_pv(screen_buf, SCREEN_PROPERTY_POINTER, (void **)&img.access.direct.data); screen_get_buffer_property_iv(screen_buf, SCREEN_PROPERTY_STRIDE, (int *)&img.access.direct.stride); img.flags |= IMG_DIRECT; loadImg(); screen_post_window(screen_window, screen_buf, 1, rect, 0); } static void loadImg(void) { img_lib_t ilib = NULL; int rc1 = 0; img_lib_attach(&ilib); img.w = 512; img.flags |= IMG_W; img.h = 512; img.flags |= IMG_H; rc1 == img_load_file(ilib,filename , NULL, &img); img_lib_detach(ilib); } The debug info shows that loading image is successful, however what I can see is a 512*512 white image on my screen. I don't know what is the problem, hope I can get some help here. Thank you very much.

Answer please.. kim dongwan(deleted) 2013-12-10T09:38:20Z http://community.qnx.com/sf/go/post106310 Sorry but I cannot. Not familiar with the NDK and I'd suggest you ask for BlackBerry specific information on the BlackBerry forums. You will have to do your homework but I know that most people's gut reaction when faced with similar problems is to say "OpenCV!" I do not know if it has something that solves your particular problem out of the box. There appears to be an "Officially sanctioned port of OpenCV to the Blackberry/QNX platform" at the following location: https://github.com/blackberry/OpenCV/ If you are after a bit by bit perfect match and don't care about the CPU use then it should be fastest to check how to access the frame via the image library and write your own matcher with for(x0 on big image) for(y0 on big image) for(x on small image) for(y on small image). If you need approximate matching, need robustness for scale/rotation/other transformations or just need more efficiency then do your research on existing libraries. -- Mate On Oct 28, 2013, at 10:23 PM, Dinyo Haygarov <community-noreply@qnx.com<mailto:community-noreply@qnx.com>> wrote: Can you point me to an existing image recognition library in the NDK which I can use? _______________________________________________ Advanced Graphics http://community.qnx.com/sf/go/post106308 To cancel your subscription to this discussion, please e-mail advanced-graphics-unsubscribe@community.qnx.com Mate Szarvas 2013-10-28T13:49:45Z http://community.qnx.com/sf/go/post106308 Can you point me to an existing image recognition library in the NDK which I can use? Dinyo Haygarov(deleted) 2013-10-28T13:23:58Z http://community.qnx.com/sf/go/post106307 It definitely is possible but QNX does not provide any libraries for that. Depending on countless factors you may either read in both images using existing API-s and do the search yourself along the lines of a 2D strstr or rely on an image recognition library. If you go with the roll your own solution approach but you hit performance issues then you can subsample both images multiple times (using a factor of 2 can be implemented most efficiently) resulting in an image pyramid and do the search at higher resolutions only in areas that gave a hit in lower resolutions. -- Mate On Oct 28, 2013, at 8:23 PM, Dinyo Haygarov <community-noreply@qnx.com> wrote: > is it possible to search for a certain image within another bigger image and retrieve it's coordinates within the bigger image? > > > > _______________________________________________ > > Advanced Graphics > http://community.qnx.com/sf/go/post106298 > To cancel your subscription to this discussion, please e-mail advanced-graphics-unsubscribe@community.qnx.com Mate Szarvas 2013-10-28T12:04:33Z http://community.qnx.com/sf/go/post106298 is it possible to search for a certain image within another bigger image and retrieve it's coordinates within the bigger image?

Di Jin(deleted) 2013-05-03T08:47:29Z http://community.qnx.com/sf/go/post100015 I created a 24 BPP surface using gf_surface_create_layer, specifying CPU_LINEARLY_ACCESSIBLE, and verified that the surface does indeed have this flag set in the surface_info_t. However, when I try and write to the surface, the access does not appear to be linear. It seems as though there is a swizzle or address redirection occurring. Drawing to a 32 bit surface and then using gf_draw_blit to blit to the 24 BPP layer_surface has the same issue. Is it possible to write linearly (with the CPU) to a displayable surface on this chipset?

Maybe, do you using plain blit2 or with additional context flags enabled, like chroma, etc? > Or maybe I'm doing something wrong ? I've seen similar behavior when forgot to use flush at the end of picture rendering in case if you have mixed environment, like software+hardware operations on the same surface. Two or more consecutive blit2()s without flush() can be optimized by hardware, you will get the last blit2() result. There are few possible issues: 1) You are not using flush() for blit2() operation. And blit2() is the only function which is called. Hardware will take video memory content for blitting in asynchronous way. For example, 1/1000 of sec is a delay between command to graphics controller has been issued and real blit2() execution in hardware. But in next 1/100000 sec you will get 3-4 optimized blit2() operations, while content of video memory was changed partially. 2) In the same time your application can use some graphics operations which are implemented in software. For example, output of some text and picture to the same surface. This is a race condition between software text rendering and hardware blit2(), so some strange visible artifacts could be observed. It depends on a GPU caching policy. So correct operations sequence will be blit2() -> flush() -> put_text("FPS: %d"). 3) You are updating your video frame content asynchronously comparing to blit2() operation. For example, there is possible such situation: two tasks are not synchronized, one is filling data which it obtains from camera and second one is doing blit2() + flush(). Due to asynchronous nature of GPU, it can execute blit2() in the same time when changing of video frame content is in process. In such case double buffering for managing video stream will be a solution. _______________________________________________ Advanced Graphics http://community.qnx.com/sf/go/post95374 To cancel your subscription to this discussion, please e-mail advanced-graphics-unsubscribe@community.qnx.com Derek Leach 2012-09-05T12:40:41Z http://community.qnx.com/sf/go/post95374 > Does mean that hardware is too slow ?

Mike Gorchak 2012-09-05T05:47:36Z http://community.qnx.com/sf/go/post95372 Hardware: Congatec Conga-CA COM Express module (Intel Atom Z510/Intel US15W) Trying to bring graphics up on this board using the generic X86 bsp. Started off with the OEM supplied bsp but now am running into the same issue. As soon as I add the libffb.so driver to the OS, the board will no longer boot and I am left looking at a display of shifting colors. The crash is before anything is running on the system so I can't get any log information or debug information. Have tried using io-display with both the Poulsbo graphics driver and the generic vesabios, the problem appears to be in the common libffb though so I'm stuck at a dead-end... Will be embarrassing to have to resort to a text-based gui! Has anybody managed to get graphics support working on an Atom-based board? Joe Thompson(deleted) 2012-09-04T21:43:34Z http://community.qnx.com/sf/go/post95236 In the our system a video stream is received from Ethernet device. And then when the all data is already collected picture is displayed. Can a shared interrupt of the ethernet and graphics controller have an impact for application performance: io-pkt-v4-hc --> irq5, io-graphics / io-display --> irq5 ? Or better idea is to separate interrupts for both devices i.e. : io-pkt-v4-hc --> irq5, io-graphics / io-display --> irq10 ? Jacek Rudnicki(deleted) 2012-08-28T20:48:26Z http://community.qnx.com/sf/go/post94943 I have attached picture that shows a black area. Rest from image lines are displayed properly.

Jacek Rudnicki(deleted) 2012-08-19T17:27:15Z http://community.qnx.com/sf/go/post94942 In my application I had to call the gf_draw_blit2() very often. When size of the image is 320x240: gf_draw_blit2 (context, img_surf, NULL, 0, 0, 319, 239, 0, 0); then everything works fine. When size of the image is 640x480 gf_draw_blit2 (context, img_surf, NULL, 0, 0, 639, 479, 0, 0); several consecutive lines in the window are black (not rendered at all). Does mean that hardware is too slow ? Or maybe I'm doing something wrong ? I'm testing against the devg-i830.so driver (Device Id: 0x2582).

Jacek Rudnicki(deleted) 2012-08-06T20:00:03Z http://community.qnx.com/sf/go/post94656 I am having the same problem, I can't find 'g8pal'. It looks like it should be a pointer to a palette of type 'img_color_t' which is just an integer. So what should the g8pal palette look like. I am new to QNX and GF graphics and am finding it hard to get things working as a lot of info is missing from QNX examples. Richard Soden(deleted) 2012-08-06T09:40:28Z http://community.qnx.com/sf/go/post94650 Hi, Application is responsible for displaying data (8-bits/pixel graymap). Data is received from Ethernet interface and displayed when image is complete (all frames were already gathered). Under Photon as solution I use PhCreateImage() and PgDrawPhImage() functions. BTW Is there any other way in order to achive a better performane in Photon ? It's time to move to GF. In the "Working with Images" chapter there is a following code: palette.ncolors = 256; palette.colors = (img_color_t*)g8pal; but compiler says that g8pal is undefined. How can I use this ? Should I generate array of colors itself (in similar way that was done under Photon, PgSetPalette()) ? What function should I use under GF as equivalent ? I found the gf_draw_image() but this function doesn't support GF_FORMAT_PAL8... Regards, Jacek Jacek Rudnicki(deleted) 2012-08-05T20:28:59Z http://community.qnx.com/sf/go/post94376 Ok, thanks Derek.

Now, I think this is the better approach here: If you are using a PtOSContainer, set the fill colour to something not common, then set the chroma on the layer to that value, and no draw. -----Original Message----- From: Don Meyer [mailto:community-noreply@qnx.com] Sent: July-19-12 1:33 PM To: advanced-graphics Subject: Displaying layer 0 gf graphics with Photon in layer 1? Is there any way to have Photon's background either not be drawn, or drawn as "transparent"? I'm trying to render some graphics on layer 0 using the gf library, and have some Photon objects overlay them, with Photon on layer 1. The problem is, Photon draws a background which totally obscures what's rendered on layer 0.

Looks like I'm following down the same road now. Thanks, Devan Devan Lippman(deleted) 2012-01-31T22:18:58Z http://community.qnx.com/sf/go/post90739 Hi , When dealing with proportional fonts, sometimes the vectors of one glyph run into the vectors of another. This is especially evident when using a font such as Nuptial BT. We need to take special care when repairing damage to such fonts. PfExtentTextCharPositions() <http://www.qnx.com/developers/docs/6.4.1/photon/lib_ref/pf/pfextenttext charpositions.html> addresses this issue in Photon environment. This position is where you should draw the next character. If you use the PF_CHAR_DRAW_POSITIONS flag, the bearing x of the following character isn't applied to the position, which is useful when you're placing cursors. What is the equivalent on PfExtentTextCharPositions() <http://www.qnx.com/developers/docs/6.4.1/photon/lib_ref/pf/pfextenttext charpositions.html> in Graphics Framework ? Please let me know regarding this.

A couple of customers running armle-v7 needed custom drivers and wrote their own. I checked whether the input DDK posted on the QNX website could be used to build a driver and was told: "The DDK won't work on 6.5.0, better to just get the imx25 BSP: http://community.qnx.com/sf/wiki/do/viewPage/projects.bsp/wiki/Freescale Imx253dsPdk and grab the source archive from it, it contains the input libs with the gf support and a sample driver."

How would this be done? Ronald Burkey 2011-08-12T16:22:11Z http://community.qnx.com/sf/go/post87957 Hi, I don't immediately see a reason for failure, either. You should examine the return value of gf_layer_attach() more closely to see what the error was. Perhaps another instance of your application was already running? In that case, you'd get an GF_ERR_INUSE. You will not see any rectangles drawn on your Windows/Linux development host; QNX executables simple will not run there. They can only execute on systems running the QNX Neutrino OS. To run your program from the Momentics IDE, you'll want to use a "C/C++ QNX QConn (IP)" launch configuration; this will automatically transfer your program to the defined target and run it there. As well, you could transfer the binary to your target and run it there directly. Hope this helps, Thomas -----Original Message----- From: Hieronim Fet [mailto:community-noreply@qnx.com] Sent: Mittwoch, 10. August 2011 00:49 To: advanced-graphics Subject: gf_layer_attach() fails.

Hieronim Fet 2011-08-09T22:53:00Z http://community.qnx.com/sf/go/post87952 Hello everyone, I`m having a problem with example program that draws rectangle. The code is from topic http://community.qnx.com/sf/discussion/do/listPosts/projects.graphics/discussion.advanced_graphics.topc8189?_pagenum=1, but I enclose copy of source without long comments so it is easier to look through. As mentioned in topic of this message there is problem with gf_layer_attach() function that fails. The output of the running program is: Number of displays: 1 Display 0: 1280X1024, refresh = 60Hz Number of layers: 1 gf_layer_attach() failed I`m sending sloginfo and pidin outputs and my display.conf. I have no idea why gf_layer_attach fails, hope you will help me.

Oscar Andreassen 2011-06-15T11:59:15Z http://community.qnx.com/sf/go/post86430 I am loading a 640X480 rgb png as follow: img_t image1; rc = img_load_file(ilib, "/tmp/black.png", NULL, &image1); I am trying to walk through every pixel in this image and do per pixel calculation. However, the loop below causes my system to crash! for (i = 0; i <( image1.h * image1.w); i++) // walk through the image using a pointer After debugging this, it seems if I use image size to be 640*361 everything works fine. So, why is it that imag1.access.direct.data is pointing to a memory size that is (640*361) where the image size is 640X480? My image is a ARGB, so it I should have 4 bytes/pixel. According to the documentation in img_t, the img_w and ima_h fields are the number of pixels. Can someone help me understand the discrepancy that I am seeing? Thanks, R.S. Reza Salehi 2011-06-03T17:33:23Z http://community.qnx.com/sf/go/post86372 Hi, I have a question in regards to the following img_t flags: IMG_TRANSPARENCY; IMG_FMT_ALPHA; I have a file that is ARGB8888. When I load this file as below rc = img_load_file(ilib, "/tmp/Day_24hr.png", NULL, &image1); the IMG_TRANSPARENCY, IMG_FMT_ALPHA are not set! Aren't these flags suppose to be set by the img_load_file, if the file is ARGB8888 png file? I am trying to blit (blend) two ARGB files, but for some reason, I keep overwriting the destination instead of the blending. I also tried the following without luck alpha.mode = GF_ALPHA_M1_SRC_PIXEL_ALPHA; gf_context_set_dst_alpha(context, &alpha); I would appreciate if someone can show me me some code on how to blend to two ARGB png files together. I am trying to evaluate the QNX for our next company project but the documentation is not always very easy to follow (at least for a non graphic expert like me) Thanks, R.S. Reza Salehi 2011-06-02T03:40:24Z http://community.qnx.com/sf/go/post86359 For some reason, when I do: image2.flags |= IMG_FORMAT; image2.format = GF_FORMAT_ARGB8888; rc = img_load_file(ilib, "/tmp/Day_24hr.png", NULL, &image1); rc = gf_surface_attach(&img_surf1, gdev, image1.w, image1.h, image1.access.direct.stride, img_fmt_to_gf(image1.format), &palette, image1.access.direct.data, 0); gf_context_create(&context); Then my call to rc = gf_context_set_surface(context, img_surf1); hangs and never returns!!! I am running out of ideas to try!!! Thanks, Reza.

Misha Nefedov 2011-05-30T17:10:33Z http://community.qnx.com/sf/go/post86234 I write a program using draw context memory by the function PdCreateOffscreenContext(). This function returns a pointer to a PdOffscreenContext_t. After that i use the function PdGetOffscreenContextPtr() to get a pointer to the shared memory object. When i have that pointer i can change data in the context to blit them on the screen by the function PgContextBlit(). However i had a problem with writing data back into the context, it was very slow. For example: ptr is the pointer to context, d is a variable. for(int i=0; i < CONTEXT_HEIGHT; ++i) for(int j=0; j < CONTEXT_WITH; ++j) { d = *(ptr + i * CONTEXT_WIDTH * 4 + j);(1) *(ptr + i * CONTEXT_WIDTH * 4 + j) = 2 * d; (2) } if i set CONTEXT_HEIGHT and CONTEXT_WIDTH small (about smaller than 256) the program run normal. if i set CONTEXT_HEIGHT and CONTEXT_WIDTH biggerl (about 1024) the program run very slow. I tried to test with bypassing either the line (1) or the line (2) and i realized that the line (2) made the program very slow. Can you help me to solve it?

Now I want to update it for QNX 6.4/6.5. I'm currently reading this doc : http://www.qnx.com/download/feature.html?programid=20957 Now I need to get the updated sources of the includes and sample drivers. But since the last changes in F27 I have not access to these sources. How is it possible to get these access?

Will the img_load_file() allocate memory for it? I am trying to read a .png file, make some modification to the file and then save it as new .png file.

Reza Salehi 2011-05-25T00:13:23Z http://community.qnx.com/sf/go/post86101 Hi Joel, I tried to use the direct pointer approach, but my system hangs. Below is a code snipet where it hangs: img_t img_day; if ((rc = img_lib_attach(&ilib)) != IMG_ERR_OK) { fprintf(stderr, "img_lib_attach() failed: %d\n", rc); return rc; } img_day.flags = 0; img_day.flags |= IMG_DIRECT; // /tmp/stop.png is the location of the file on the target VM system img_template_file_Day = "/tmp/stop.png"; // The code hangs after making the call below. If I don't set the IMG_DIRECT flag, it works. if ((rc = img_load_file(ilib, img_template_file_Day, NULL, &img_day)) != IMG_ERR_OK) { fprintf(stderr, "img_load_file(%s) failed on Day Template: %d\n", img_template_file_Day, rc); // return rc; } Reza Salehi 2011-05-24T23:06:36Z http://community.qnx.com/sf/go/post86097 Well, I think my problem is that I am not familiar enough with the graphic sub-systems of QNX to know what I want to do :). Basically, I have some graphic artists that are providing me base .png files. I need to draw an ellipse based on some dynamic data and save the result as another .png file. So, whatever is the fastest to accomplish this would work for me. I appreciate it if you have any suggestion or code snippet to help me get started.

Joel Pilon(deleted) 2011-05-24T18:30:37Z http://community.qnx.com/sf/go/post86089 I am trying to read a .png file, modify it and write a back to the file system. In order to do that, my understanding is, that I need to use both gf and img libraries. I don't want to use any specific HW to attach to as I don't need to display my .png file. All I want to do is to be able to create surface so that I can modify my .png file. In order to create a surface, I need to first attach to a device. My understanding is that I can use devg-flat as a device. However I am not sure, how to install devg-flat driver and related files into my IDE and target. I also don't know how to use devg-flat in the call gf_dev_attach() call? I have already added libffb.so to extra libraries section of IDE. I appreciate it if anyone can give me some pointers on this.

Reza Salehi 2011-05-19T23:44:14Z http://community.qnx.com/sf/go/post85979 I'd suggest taking a look at libimg. There also doc for the api as well. The gf api allows you to render things like ellipses and libimg would allow you to write data from gf surfaces as pngs.

I am trying to use Momentics IDE to connect to a x86 VM target using qconn. What I want to do is to be able to draw an based on some parameters and then save it in a PNG format on the target file system (VM running neutrino). I would like to then be able to load the png file in a browser and display the image. Can anyone someone tell me what is the best way to start? Is GF the correct place to start. With GF, I could not find anyway to render to a file rather that a graphic device! I apologize if some my graphic terminology is not correct. I am trying to evaluate the QNX platform for a future project and this would help me get started. Thanks in advance. Reza.

The other formats are all RGB so they work. If you need to transfer YUV data between surfaces you'll have to manually copy this. Alternately depending on your application/use-case you could have multiple YUV surfaces and just re-target the layer to point at the different surfaces.

The PfFindFont() is similar to PfGenerateFontName(), it only returns FontID. I am not sure why you need it. Well, I was simply following the sample code in the PfRenderCx() API doc, as you suggested. The sample code calls PfFindFontCx(). Personally, I'm willing to do without it, even though I don't see why it should be failing. > The 'Description' you got from the Generate function is good to be used with the subsequent PfRenderCx(). Okay, I think you're suggesting something like this: FontName Description; char *FontName = "Courier10 BT"; pf_point_t pp = { 50, 50 }; int FontSize = 10; FontServer = PfAttachCx (NULL, 0); ... check for error ... if (NULL == PfGenerateFontNameCx (FontServer, FontName, 0, FontSize, Description)) { ... error ... } i = PfRenderCx (FontServer, FontServer, Description, 0L, 0L, "Hello, world!", 0, 0, &pp, NULL, Callback); ... check for error ...
