    I developed an object to create thumbnails (using hi-quality interpolation). One thing I'd like to do is adding contrast to small images. Is it possible to add contrast to an image using GDI+? Thanks, Matteo Frana F2 .net engineering s.r.l. Italy

    Or, maybe better, is there a way to "sharpen" an image using GDI? Thank you, Matteo Frana F2 .net engineering s.r.l.
