- 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.
- Ptiff is a type of image file that is created by compressing a TIFF (Tagged Image File Format) image using a wavelet-based encoding, known as pyramidal encoding. This type of file can store both lossy and lossless compressed images and is often used for storing large-scale images such as aerial photographs or medical images.
