Converting CAL to QRT

A CAL image file represents a monochrome bitmap image that uses the CALS raster image standard for storing graphics data. This standard was created in the 1980s by the US Department of Defence as a compressed interchangeable image format. CAL and CALS are extensions used for similar purposes.

The QRT format file is associated with the QRT Ray Tracer, also referred to as Quick Ray Tracer. QRTs are uncompressed raster graphic images which contain 3D scenes for ray tracing. Although they haven't been used very frequently in past years, they can be used for various rendering applications.
