UEZ Posted September 24, 2019 Author Posted September 24, 2019 (edited) I've update the function. Except 8-bit TGA images all other formats should be converted and displayed fast as the lines will be copied using memcpy. 8-bit images have a color tables where the code has to get the appropriate color and poke it to the GDI+ bitmap memory. If you are interested please have a look to the 1st post above. Autoit is probably not fast enought to decode RLE compressed image, so I will skip it. Maybe I will create a Dll for TGA decoding incl. RLE compressed images... Edited November 8, 2019 by UEZ Please don't send me any personal message and ask for support! I will not reply!
