When I try to draw an image with alpha channel using OpenGL ES on Android with GL_BLEND disabled, the area that should be transparent is drawn in black…
Who can I choose the color that is used to draw the area that should be transparent
The color will most likely depend on how the original image is encoded. If your transparent pixels are encoded as rgba(0,0,0,0) you will get black. If you those pixels are encoded as rgba(1,0,0,0) you would get red.
