Contrast and brightness of an image

Recommended Posts

How can I change the contrast and brightness of an image before or after _GDIPlus_ImageLoadFromFile. I would create a watermak behind the text.

You could make external calls to ImageMagick.

Edit: Capitalized the "M" in ImageMagick.

Edited by JohnQSmith

Whenever someone says "pls" because it's shorter than "please", I say "no" because it's shorter than "yes".

Found a solution in the topic:

Change alpha's pic from only one element in GUI, not all.

I can make use of the ColorMatrix in GDI+ explained in this topic. ;)
