Hello,

I wish to create a Screenshot. How can I access to the actual display buffer to read pixels please ?

Thank you.

GDISP drivers have an interface for reading out the framebuffer. You can use that to get direct access to the pixel data. But keep in mind that uGFX itself doesn't need a framebuffer. So there are certain setups where this won't be possible because there's no framebuffer accessible.

If this is a higher end application you might already be using Pixmaps which are essentially framebuffers. The Pixmaps have high-level API to return a gdispImage object of the framebuffer contents.

It works. Thank you for your help.
