Convert MTV to PFM

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 Portable Floatmap (PFM) file format, also known as Portable FloatMap, is an image file format designed to store High Dynamic Range (HDR) images using floating-point values. Developed in the spirit of the Portable Pixmap format, PFM files contain image data with resolutions and byte order specified in the header. This format is particularly useful for applications requiring precise image data, such as computer graphics and image processing. PFM has been widely adopted in the IT industry for its ability to handle a wide range of pixel values beyond the standard 0-255 range, making it ideal for HDR imaging and other advanced visualizations.
