Information about PNM and PNG file formats

🔸 File format PNM PNG
🔸 Full name Portable Any Map Image PNG - Portable Network Graphics
🔸 File extension .pnm .png
🔸 MIME type image/x‑portable‑bitmap, image/x‑portable‑graymap, image/x‑portable‑pixmap, image/x‑portable‑anymap image/png
🔸 Developed by Jef Poskanzer PNG Development Group
🔸 Type of format Image lossless bitmap image format
🔸 Description PNM is a bitmap image in the Portable Any Map format that was originally developed for processing and storing several types of monochrome and color images without compression and grayscale images. Bitmap graphics data in a PNM file are stored using ASCII or binary structure. Portable Network Graphics (PNG) is a raster graphics file format that supports lossless data compression. PNG was created as an improved, non-patented replacement for Graphics Interchange Format (GIF) and is the most used lossless image compression format on the Internet. However, PNG itself does not support animation at all. MNG is an extension to PNG that does. Members of the PNG Group designed it.
🔸 Technical details PNG supports palette-based images (with palettes of 24-bit RGB or 32-bit RGBA colors), grayscale images (with or without alpha channel), and full-color non-palette-based RGB[A] images (with or without alpha channel). However, PNG was designed for transferring images on the Internet, not for professional-quality print graphics, and therefore does not support non-RGB color spaces such as CMYK.
