Convert CR2 to PPM

Understanding CR2 and PPM file formats

CR2 (Canon Raw Version 2) is a raw image file format produced by Canon digital cameras. It stores unprocessed image data directly from the camera's sensor, allowing for high-quality post-processing and editing. PPM (Portable Pixmap) is a simple, uncompressed raster image format that stores pixel data in a plain text or binary format, commonly used for image manipulation and transfer between different platforms.
