Hi All, I'm just wondering if there is a simple and fast way to get color scheme from an image?? I didn't find any result on the internet after searching for 1:30 hour... I'm not expert at Graphics codes and these stuff, but for my project the method should be very fast because it will have to get 30 color schemes of 30 different images(256x160 pixels) just in under 2 sec... so any advise where to start or how to calculate colors and extract them from an image??

What are you consider a color scheme? Do you mean the color palette of the image?

I think you could not find anything because your idea is quite original. Maybe it even makes some sense, for developing and fast applying color schemes to some limited/fixed set of designs. The picture could serve as a model "preview" of the color design and the source of color values at the same time.

So, instead of searching the Web, you could develop your idea by yourself. What is unclear about its implementation?

In WPF, BitmapSource has a Palette[^] property, however consider that not all image formats has palette. Only indexed (like tiff, gif and some kind of bitmap) formats has palette, for other formats you have to scan the image pixels and gather the color information from there...
