Parameters

ImageID: GdPicture image identifier.
RemapTable: Array which specifies the color remap table. Each entry is a Imaging.ColorMap oGdPictureImaging.

Return Value

A member of the GdPictureStatus enumeration.

This method requires the Image Documents component to run.

Replacing shades of red by shades of blue within a an image.

        remap.NewColor = Color.FromArgb(0, 0, index);
