Convert DCM to PNM

DCM, short for Digital Imaging and Communications in Medicine, is a file extension used for medical imaging data. Originating from the DICOM standard developed by the National Electrical Manufacturers Association in collaboration with the American College of Radiology in the 1980s, it facilitates the storage, transmission, and management of medical images and related information across various devices. Its uses span hospitals and clinics, where it integrates imaging modalities like MRI, CT scans, and X-rays, ensuring interoperability and enhancing diagnostic accuracy and efficiency.

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.
