Subject: Color manipulation

---

Hi,

One of our clients is a large photographic company and they currently
use a third party application to color correct images before printing
them. Our company has been asked to re-write this part of their
production. The problem is I'm a .NET developer and my knowledge of
color is minimal and the research i have done so far suggests it can be
quite complex/mathmatical.

The functionality i have to replace is adjusting the red, green, blue,
density, contrast and saturation of an image. I've played around with
the colormatrix class from GDI+ and can change the RGB valus ok but i'm
not sure how to do the others. i think the density looks like
brightness to me.

done anyone know how to do this? i'm using .NET which has wrappers for
all of the GDI+ objects. if anyone knows of any conmponents that could
do this then great!

Thanks in advance
