Now, here is my first set of functions for semi-transparency. It was designed as a plugin lib. Since i don't know yet how to patch, i'll just upload each file. :)
   xlcd_alpha.c (7.5 KiB)
(application/octet-stream)    xlcd_alpha.h (5.1 KiB)
   alpha.c (2 KiB)
   button.320x240x16.bmp (33.8 KiB)

Can you explain what this does for us not so smart people. Sounds exciting, but I have no clue.

These are just simple functions for drawing semi-transparent rectangles, pixels and iamges with an alpha channel.. Io can read an article about alpha channels here: http://en.wikipedia.org/wiki/Alpha_channel
Semi-transparent rectangles are just unifor-coloured bitmaps with a uniform alpha channel.

you forgot to add france.320x240x16.bmp
Comment by Pascal Briehl (ColdSphinX) - Saturday, 14 April 2007, 18:45 GMT
also aunknown.c
Comment by Ştefan Săftescu (SliMM) - Sunday, 15 April 2007, 10:47 GMT
Sorry for that. I'll remove aunknown.c from the patch, as that is just another test file. I'm new to patching. france.320x240x16.bmp is now attached. It's a picture from google, since I didn't want to attach the original one.
