I use Allegro.
And I have a program, which calc transparency of about 16 000 pixels in one
frame.:)
If I use getpixel, getr16, getg16 and getb16 and some other functions to get
transparent color between two colors, it is too slow. I use 640x480/16bit
mode.

Maybe I must do one integer:
int transparentpixel [65536][65536]; and at begin of program calculate
every pixels transp color?:) That was a joke.:)

Help me!
Thanks,
