I'm having a problem with transparent 32-bit PNG's on both the emulator and the G1. They load fine, but I can't change their alpha value unless the texture is fully opaque to begin with. For a simple example:
glEnable (GL_BLEND); glBlendFunc (GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA); glBindTexture(GL_TEXTURE_2D, fully_opaque_texture); // all pixels are opaque glColor4f(1, 1, 1, 0.5); glDrawArrays( ... ) // displays half transparency (correct) ... glBindTexture(GL_TEXTURE_2D, transparent_texture); // some pixels are transparent glColor4f(1, 1, 1, 0.5); glDrawArrays( ... ) // displays as fully opaque (wrong) I've also tried the following (as suggested on another thread) with no luck: setEGLConfigChooser(8, 8, 8, 8, 0, 0); getHolder().setFormat(android.graphics.PixelFormat.RGBA_8888); --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Android Beginners" group.
