- Description
- Group 4 (G4) used for black and white lossless compression to maintain high-quality images, commonly used in TIFF format compression by fax machines. A picture is seen as black dots and lines on a blank page; the fewer the dots and lines are, the lesser the file size.
- The XPM (X11 Pixmap Graphic) file format is a plain text file format used to store pixmap images, which are pixel-based graphics. It is designed for use with the X Window System, commonly used in Unix and Linux environments. XPM files define images in a structured format, using ASCII text to describe each pixel's color and location within the image. This format supports both monochrome and color images and allows for the definition of custom color palettes.
