Convert MTV to CALS

The MTV Raytracing Image Format, named after its creator Mark T. VandeWettering, is a simple, uncompressed true-color raster image format used primarily by the MTV Ray Tracer program. It employs the MTV or PIC file extension and is similar to the binary PPM format. Developed in the early days of ray tracing, the MTV format gained popularity due to its straightforward design and ease of use. It supports true-color images and is often utilized in conjunction with other ray-tracing utilities for rendering high-quality graphics.

The CALS (Continuous Acquisition and Life-cycle Support) Type 1 Image file format, developed by the United States Department of Defense in the mid-1980s, is a standard for storing raster (bit-mapped) image data, typically black-and-white. It ensures efficient data interchange and retention of orientation metadata. The format supports both uncompressed and compressed (using CCITT Group 4 compression) images. This standard was part of the broader CALS initiative aimed at improving electronic publishing and data management within the federal government.
