- 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.
- This format was developed by Kodak in order to store images on optical or other media. It is used as a format for archiving scanned documents on Kodak devices. It encodes images in 24-bit color and supports resolutions of up to 6144x4096 pixels.
