I'd like to know
If there a way to change a TImage contrast and brightness
Then save the new TImage
I wonder if someone can help me...I have searched in vain for this. I
need to implement brightness and contrast adjustment of bitmap images,
similar to that found in PaintShopPro and other raster image packages.
We have a system where images are retrieved from a scanner (which has
brightness and contrast controls), but I need to allow the user to fine
tune brightness and contrast after the scan, hence the requirement. I
realise you would only get a small range of adjustment.
The images are 24 bit colour windows DIBs, fwiw. Also, in case anyone
knows of code samples, the project is Delphi based, but I am happy with
C/C++ also and can port Unix code.
Even if anyone can give general information, or clues as to what
algorithms to use, it would be much appreciated.
Many thanks in advance.
