    how to increase alpha resolution?


    i'm quite new to this openGL ES and EGL stuff.
    at the moment im porting a win32 openGL app to openGL ES.
    my only problem at the moment is that i can only get 4 bit (16 steps) of alpha blending.
    so my fading out textures look realy ugly.
    in the openGL version i had a smooth transition, in my GLES/EGL port the fade out is stepped.
    is there a EGL or GL ES flag to increase the resolution of the available alpha chanel?

    many thanks!

    When you initialize the display using EGL, you can query what kinds of resolutions the system supports, and select from what's available.
    You can't change the alpha resolution after you have already created the display.
