Hi;
Here's RFC for the extension. I've tested the import/export functionality
with RGBA images on Android Celadon with a custom NDK app that draws a
textured cube using AHardwareBuffer contents. Export feature I tested
by creating just a regular image (LunarG cube texture) and then exporting
that as AHardwareBuffer, modifying buffer and then rendering the
results.
I wanted to send this RFC to get some comments on what's missing and if
I have understood the specification correctly. If supporting only RGBA
for now is fine, I believe we could go forward with these bits.
Any comments appreciated!
Thanks;
