i searched the forum, but didn't find anything. has anyone an idea or ever done it with autoit ? simple image transforming, like sharpness, brightness, blurring etc. ? maybe, does gdiplus.dll feature that ? here is a tutorial on how to do it the hard (mathematical) way. http://lodev.org/cgtutor/filtering.html before i try that, i wanted to know if there is already an existing project or an idea or anyone has experiences. thx
