Just wanted to tell you guys here that I have posted a small set of functions here:
http://www.dannywartnaby.co.uk/rgt/index.php?board=8;action=display;threadid=3514
It includes:
colorize_image(source_image,destination_image,color,percent)
flip_image(source_image,destination_image)
mirror_image(source_image,destination_image)
greyscale_image(source_image,destination_image,percent)
invert_image(source_image,destination_image)
brighten_image(source_image,destination_image,percent)
There is a version for DBPro and a version for DBC Enhanced, so make sure you get the right one!
Later, kenmo
