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.
Compressed bitmap image that uses wavelet compression instead of the DCT compression used by standard .JPEG images; supports 16-bit color, alpha transparency, and lossless compression.
