How to convert a color (in RGB mode) to transparent color for PNG using C#?

Question

I will be converting a jpg to png and than I wish to remove an RGB color with values (254,242,211) to a transparent color in PNG using C#. Can anyone point me to a good tutorial and/or code?

Answer 1

Try to do folowing:

Bitmap bmp = new Bitmap(_jpegFilePath);
bmp.MakeTransparent(Color.FromArgb(254,242,211));
bmp.Save(_pngFilePath);

Should work.

Regards.
