DFONT to MTV Converter

MTV is a simple raster image format created by Mark T. VandeWettering for the MTV Ray Tracer, a ray tracing program released in 1988 as one of the early publicly available ray tracers distributed through Usenet. The format stores 24-bit RGB images with a minimal text header followed by raw pixel data. The header consists of a single line containing the image width and height as ASCII integers, followed immediately by the pixel data where each pixel occupies three bytes (red, green, blue) arranged in row-major order from top-left to bottom-right. The MTV Ray Tracer itself was significant in the history of computer graphics — distributed freely via the comp.graphics Usenet newsgroup, it introduced many programmers and students to the principles of ray tracing: ray-object intersection, reflection, refraction, shadows, and recursive shading. The MTV format was the program's native output, and its simplicity made it easy for users to write custom viewers and converters on whatever platform they had access to — a practical necessity in the fragmented Unix workstation landscape of the late 1980s. One advantage is extreme implementation simplicity: the format can be read in a handful of lines of code in any programming language, with no libraries, no compression algorithms, and no metadata parsing required — just read two integers and then read width x height x 3 bytes of pixel data. The format's historical significance in the computer graphics community provides another dimension — MTV files from early ray tracing experiments represent primary artifacts from the era when ray tracing transitioned from academic research to accessible software. MTV files are supported by ImageMagick and various legacy graphics tools.
