I am seeing slight data corruption using the Martin Wright's great Convim w/dlls (latest versions) some times the 0-0-0 rgb values that are used to get alpha mask are changed to 1-1-1 (only near adjacent colored pixels).I verified that the original 24bit bmp data is clean (0-0-0) but that after conversion to Dxt1 via Convim the corruption occurs.I have preferred MW's programs for the high quality conversions and mipmaps over previous MS tools as the results of the MS tool was very poor mips and the results were completely unacceptable.My bmps are 10000x10000 in size and result in more than 1400 dxt1 bmps.thoughts and comments appreciated.Thanks.
