    Comments

    A raw image file contains no header or identifying information. ImageGear can load images of proprietary or unsupported formats as raw data. Since ImageGear cannot obtain parameters, such as width, height or bits per pixel from the file, the application should specify them. This can be done by using the ImGearRawLoadOptions class derived from the ImGearLoadOptions, to specify loading options for header-less RAW formats and passing them to the LoadPage method.
