rotate display   
Hi,

is it possible to rotate the display during runtime of io-graphics?
I know, that I can rotate the display using the hook option with devg-rotate90.so and devg-rotate270.so. But to rotate 
it during runtime of our application, I need to kill io-graphics and restart it with the corresponding hook option. Is 
there no other way to this?

We are using QNX 6.3.2 with Photon.

Best regards,
Stephen

Unfortunately in 6.3.2 you can only re-start the io-graphics. The rotation API (PgPHookRegister) is available in 6.5.x 
only.

Re: rotate display   
Thanks for your answer!

It seems that our customer is planing to upgade their QNX from 6.3.2 to 6.5. Can you make a statement about the 
preformance of the new screen-rotation technique in QNX 6.5. At the moment it takes about 2-3 seconds to rotate the 
screen. And the CPU load is very high.
Our hardware is very similiar to the Atmel AT91SAM9263-EK. The display resolution is 640x480.

Best regards,
Stephen

Re: rotate display   
Dear Stephen
We are using QNX 6.3.2 with Photon with Ateml AT91SAM9263 processor on coustom board.
Using LCD display 240*320, i want to rotate the photon window by 90 degree.
The display driver is the same which the QNX BSP provide.
I used the hook  option with the io-graphics command but it doesn't rotate.
Can u help me by providing the exact command for rotation.
I added the rotate90.so file in my build file.

Hi Mukesh,

this is the command, which I use:
"io-graphics -datmel hook=devg-rotate90.so,photon,xres=480,yres=640,bitpp=8 -pphoton"

Re: rotate display   
i tried the option given by u but it doesn't work. It shows io-graphics stopped in pidin command & display is blank.

Re: rotate display   
first try to start the io-graphics from console via telnet or a serial connection. Then check sloginfo for debug outputs
 from io-graphics.

Re: rotate display   
Sloginfo gives error "Failed to open hook dll devg-rotate90.so, unable to library file".
though i have put the dll in /usr/lib and /lib/dll path also set LD_LIBRARY_PATH to these locations.
Also when i use pidin command with mem option the hook dll devg-rotate90.so is not shown in the list.
Please check my build file which i attached in my last post.

Re: rotate display   
I don't see any mistakes in your buildfile. But I am not a QNX specialist. Sorry.

Check the execute permissions of the devg-rotate90.so.
