Why pixel by pixel? That's very slow!

Where are you stuck? for copy-paste see google.

It depends on what libraries do you want to use, what UI library/framework, what is the application type. You need to tag such things if some UI or graphics is involved.

SetPixel - set points int Bitmap to concret color, but I need LoadBitmap and then I need draw bitmap pixel by pixel, because I must cut points(pixels) that have color, which I dont need

Worst thing to draw anything is using SetPixel. You should better use System.Drawing.Bitmap.LockBits:

With WPF, it can be done using the class System.Windows.Media.Imaging.WriteableBitmap:
