Convert PNM to DPX

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 DPX (Digital Picture Exchange) 2.0 file format is a widely adopted standard for exchanging high-quality, resolution-independent, pixel-based images, primarily used in the film and post-production industries. Developed by the Society of Motion Picture and Television Engineers (SMPTE), DPX files store individual frames of scanned film or digital images, supporting both color and grayscale data. Introduced in 1994 and updated to version 2.0, DPX facilitates the transfer of digital images for film recording and digital cinema projection, ensuring consistent image quality across different platforms and devices.
