Can I use all OpenGL function in Defold?
How can I use functions glReadPixels, glCopyPixels, glDrawPixels, glBitmap and others in Defold?
Class “render” doesn’t have these functions.

No, they are not available. What do you want to achieve?

I need paint in the game. My task is to create a coloring book. Thank you!

It’s probably cumbersome but I think you can use the GUI for that. See http://www.defold.com/ref/gui/#gui.new_texture

Thank you, I tried use this method, but the number of textures is limited.
I can create only 128 textures. I have not found method unite texture to avoid errors.
