Dear Oleg,

Thank you for your valuable support.
We were trying to understand the concepts which you discussed in your earlier reply to use the frame buffer pointer in 
QNX 4.25. Please see our replies inline.

[Oleg] >> You can create at least two configurations with Photon components to achieve your target.
You can disable (just do not launch) all unneeded Photon components like pdm, pwm, etc and create PtRaw-based 
application maximized to whole screen.

[Honey] >> We have edited our ph script as follows:
Added the following lines.
1. export PHWM=""
2. export PHWMOPTS=""
3. export PHPDM_DISABLE=""
and commented out pdm invokation in the script.
Then we rebooted our QNX 4.25 machine. We ensured that pdm, pwm are not running by running pidin command.
Then we started learning on PtRaw widget from "Raw drawing and animation" chapter from Photon MicroGUI manual.
Created a sample application which has a PtRaw widget and a PtRect canvas placed on it. Also draw an ellipse and fill 
color on it. This is what we can achieve till now.
Hope this is the way you mentioned how to get the raw drawing feature using frame buffer. Please correct us if we are 
wrong.

[Oleg] >> Also you can try to launch Hydra.ms to switch to graphics mode and access framebuffer directly using 
framebuffer pointer. To get framebuffer pointer you can use show_pci or show_vesa utils.

[Honey] >> We can't understand this fully. We have tried to run show_pci command. Attached file (show_pci.png) is the 
output which we got. show_vesa command is not found in our QNX 4.25 machine.
Also we are not clear about Hydra.ms; so didn't make a trial on it. How hydra.ms can be used to access frame buffer 
directly?

Could you please detail on our concerns?

Thank you for your understanding and patience.
Regards,
Honey S
