Conversion from ie8g to 24rgb does not use the blackvalue and whitevalue for properly scaling the image (in case you do not use all the black levels).
Conversion from ie16g to 24rgb does consider the blackvalue and whitevalue.
It would be really great if it could, otherwise, can you suggest the best way to scale the ie8g manually before converting. I don't want to have to make a copy of the image just to scale it before converting to 24rgb (I have to keep a copy of the original one)
Hello, next minor version will consider BlackValue/WhiteValue when converting from ie8g to ie24rgb. Also, it will have TIEBitmap.StretchValues() method which does the same job (stretch values from BlackValue to WhiteValue), without converting the image. The code is already implemented.
