Graphic Compression
Three main formats for saving pictures: JPEG GIF PNG
Each has its use!
JPEG
Joint Photographer’s Expert Group 16 million colors Lossy compression
Picture quality will deteriorate, but it is unnoticable until you allow extremely low quality
Up to 25:1 compression can be achieved 1 megabyte file can be compressed to 40 K
without a perceptible change to the photo
GIF
Graphics Interchange Format 256 colors
Clipart type files, with need for fewer colors Can save with fewer colors to save space
Lossless compression Provides a way to store multiple images for
animated GIF’s Owned by Compuserve, so there are fees
involved
PNG (pronounced PING)
Portable Network Graphics Lossless compression, generally slightly
better than GIF Supports up to 48 bit color A good choice for graphics such as text
labels, but JPEG is still better for photos
