- 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.
- Windows vector graphics format recognized by many image-editing applications; basically a 32-bit version of the original Windows Metafile Format (.WMF), which only supports 16-bit data; saves image data in an RGB format and does not support CMYK data.
