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.
Image file format related to the .PNG format, but uses lossy compression like standard .JPG files; developed as a sub-format for .MNG objects, but can also be used as a standalone raster image format.
