About PBM (.PBM)
PBM stands for Portable Bitmap Format, a simple image file format used to store black-and-white bitmaps. It is part of the Netpbm family of formats, designed for easy image exchange between different platforms. PBM files are often used in early computer graphics and printing applications due to their straightforward structure. Interestingly, PBM files represent images using a grid of pixels where each pixel is either black or white, requiring minimal storage space.
Technical Details
Technically, a PBM file starts with a 'magic number' (P1 for ASCII format or P4 for binary format) that identifies the type of encoding used. The file then contains width and height information followed by the pixel data, with '1' representing black pixels and '0' representing white pixels. The binary version is more compact and faster to process, while the ASCII version is human-readable. PBM files are often converted to other formats like PNG or JPEG for more complex image manipulation and display.
Additional Information & Use Cases
PBM files are uncompressed and stored in plain text or binary form, making them easy to read and edit with basic text editors. This simplicity allows them to be widely supported across various software and tools without compatibility issues. The format was created in the late 1980s as part of the Netpbm toolkit, which aimed to provide a universal set of image formats for cross-platform use. Because of their minimalistic design, PBM files are not suitable for detailed or color-rich images but excel in simple graphic representations.
