- Description
- The Portable Bitmap (PBM) file format is a monochrome image format that is part of the Netpbm suite, which also includes Portable Graymap (PGM) and Portable Pixmap (PPM) for grayscale and color images, respectively. PBM files represent images as a collection of black and white pixels in a very simple, text-based or binary format, making them easy to read and manipulate with basic text editing or binary tools. The simplicity of the format allows for straightforward editing and conversion to and from other image formats, though it lacks support for color or grayscale nuances. Due to its simplicity and portability, the PBM format is often used in research, development, and applications where basic visual representation is needed without the overhead of more complex formats.
- Image stored in the JPEG XR format, which was originally developed by Microsoft for Windows Media software; supports deep color images with 48-bit RGB; used for high-resolution professional image editing; also supports lossless and lossy compression.
