- Description
- It is an image compression codec file with the same quality as .jpeg, but that is ten smaller. It supports HDR (High Dynamic Range). SDR (Standard Dynamic Range), and WCG (Wide Color Gamut) images. Also, it contains both the image sequences and image items. The only pitfall is that a few applications support it.
- 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.
