Convert PNM to MTV

The PNM (Portable Anymap) file extension, developed by Jef Poskanzer in the 1980s, stands for Portable Any Map. It is an uncompressed raster graphics format designed for portable image storage and exchange, encompassing three sub-formats: PBM (Portable Bitmap), PGM (Portable Graymap), and PPM (Portable Pixmap). PNM files store image data in plain text or binary format, ensuring easy usage across different platforms and applications. This format is widely supported by various image editing software and is valued for its simplicity and lossless compression.

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.
