DIBs or both pages must have the same color space.
Use ImGearRasterProcessingVerifier.CanApplyMerge method to check whether the operation can be performed.
If the images are paletted, the arithmetic operation is applied to the pixel values (indexes) rather than to the palette entries. This may result in unexpected effect with certain palettes, for example if the palette is reversed. In such cases, consider converting the image to a non-indexed colorspace, such as Grayscale or RGB, before applying the operation.
// Opens an image and merges it into an already open image. using (FileStream file = new FileStream("photo.jpg", FileMode.Open, FileAccess.Read, FileShare.Read)) { ImGearRasterPage igRasterPageToMerge = (ImGearRasterPage) ImGearFileFormats.LoadPage(file, 0); // Subtract the opened image from the existing image. ImGearRasterProcessing.Merge(igRasterPage, igRasterPageToMerge, 0, 0, ImGearMergeModes.SUB); }
