Convert CR2 to PNM

The CR2 (Canon Raw 2) file extension, developed by Canon Inc., is a digital image format used for capturing high-quality raw data from a camera's sensor. Introduced in 2004 with the Canon EOS-1D Mark II, the CR2 format preserves all the original details and metadata, allowing for extensive post-processing flexibility. It is preferred by professional photographers and IT specialists in image processing for its ability to retain maximum image information, facilitating enhanced editing and manipulation capabilities. The CR2 files are integral to workflows that require precision and detail, making them indispensable in fields like digital photography, imaging technology, and computer graphics.

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.
