Pixel Format Limitations
Although GemBox.Imaging supports reading most of the image pixel formats, image pixel format can change on image transformation operations or saving the image. But the output will still be as expected.
For example, GemBox.Imaging can read Indexed8 pixel format, but after image transformation, the output will be Bgra32 pixel format.
