How to replace glGetTexImage?

Question

Android

There is a texture in memory, you need to get it to write to a file. I heard that you can somehow do it through FrameBuffer, but all attempts have not been successful so far.

Answer 1

It is possible, through FrameBuffer and ReadPixels. The only downside is it's very long.

Answer 2

In the android version, as far as I know, there is no way on pure eGL. In SDL - I did it through Surface, i.e. the object after loading into eGL did not kill. The option is very suboptimal from memory.
