Parameters

page

First image to merge. It will contain resultant image after merging.

pageToMergeWith

Second image to merge.

left

Left position of the source image on the destination one.

top

Top position of the source image on the destination one.

mode

Merge mode.

channels

Range of channels.

Both page DIBs 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.
