Graphic Format:
- PNG- Portable Network Graphics. Used as a replacement for GIF and handles 1 to 48 bit images but its LZW is owned by Unisys which can't be included in commercial software without paying license fees to the owners.
- GIF- Graphics Interchange Format. A popular picture and animation tool that has 256 colors. These pictures can also be interlaced to see low resolution versions of the picture before download.
- JPG/JPEG-Joint Photographic Experts Group. It is said to be the most efficient image storage method that compresses some of the data and then it throws it away. Which is the most standard format for web graphics that can store 24 bit color what makes it suitable for professional use.
- TIFF- Tag Image File Format. A 24 bit format which supported compression and made it less painful. But basically a very popular professional graphics format and the compression is LZW and owned and licensed out by Unisys is another pain.
