// Separate original image into separate images for each channel.

ImGearColorSpaceIDs igColorSpaceID = igRasterPage.DIB.ColorSpace.Value; // Create a blank image with the same attributes as the original image. ImGearRasterPage igRasterPageNew = new ImGearRasterPage( igRasterPage.DIB.Width, igRasterPage.DIB.Height, new ImGearColorSpace(igColorSpaceID), (int[])igRasterPage.DIB.ChannelDepths.Clone(), true); // Separate new image into separate images for each channel. ImGearChannelRef[] igChannelRefNew = ImGearRasterProcessing.SeparateChannels(igRasterPageNew); // Update the first channel of the new image from the original image. ImGearRasterProcessing.UpdateChannelFrom(igChannelRefNew[0], igChannelRefOriginal[0]); // Combine channels back into new image. igRasterPageNew = ImGearRasterProcessing.CombineChannels( new ImGearColorSpace(igColorSpaceID), igChannelRefNew); | |
