I'm using OpenGL ES 2.0 in an Android application to upload a texture atlas, which can be quite big in size (let's say 4096x4096). (I'm uploading the corresponding bitmap data in smaller pieces, using the texSubImage2D() function.)
When I'm done, I'd like to check the texture that I've just finished uploading. I'd like to do this from the development environment - in a similar way that you can check a Bitmap from Android Studio while debugging, when it displays the contents of the Bitmap as an image.
Is this possible? How can I do this?
I think (based on this screenshot) that Google's open source GAPID (Graphics API Debugger) should be able to do this. (Apparently it used to be part of Android Studio, but not any more - now it's a standalone application.) Version 1.0 was released in 2017 December.
Unfortunately, there is a yet unfixed issue that prevents me using it in my application (it exits right after startup), but it should hopefully be fixed soon.
