.PGF File Extension
File Type 1Progressive Graphics File
What is a PGF file?
A PGF file is a bitmap image created in the Progressive Graphics File (PGF) format. It supports lossy and lossless compression and a variety of color models, including indexed color (256 palette size), grayscale, RGB color, ARGB color, l*a*b color, and CMYK color.
The PGF format was designed to improve on the JPEG standard by reducing compression time and increasing compression ratios. The format offers progressive transmission, which means the image can be viewed at a low quality before all of its data is fully downloaded and then increases as more data is received. The format also includes representation of multiple resolutions, which means that it does not need to store separate preview images, such as thumbnails.
NOTE:PGF was developed at the same time as JPEG 2000 and initially released in 2000. The format was developed at the Institute of Theoretical Computer Science at ETH Zurich university.
