At first I was using tessdll. I need to convert a bitmap that I have in memory to an unsigned char *. I used LockBit, then Scan0 on the BitmapData, and I have my unsigned char *.
Unfortunately this does not work when passed to TessDLL api. Do you know how to format the unsigned char * the way tess dll wants it?
