As there is little control over display fonts, however, this feature is rarely used. allowing text labels as text (not embedding them in the graphical data).storage of application-specific metadata.In 1989, CompuServe released an enhanced version, called 89a, This version added: This version already supported multiple images in a stream. The original version of GIF was called 87a. Since this was more efficient than the run-length encoding used by PCX and MacPaint, fairly large images could be downloaded reasonably quickly even with slow modems. GIF became popular because it used Lempel–Ziv–Welch data compression. This replaced their earlier run-length encoding format, which was black and white only. GIF images are compressed using the Lempel–Ziv–Welch (LZW) lossless data compression technique to reduce the file size without degrading the visual quality.įurther information: § Unisys and LZW patent enforcementĬompuServe introduced GIF on 15 June 1987 to provide a color image format for their file downloading areas. These palette limitations make GIF less suitable for reproducing color photographs and other images with color gradients but well-suited for simpler images such as graphics or logos with solid areas of color. It also supports animations and allows a separate palette of up to 256 colors for each frame. The format supports up to 8 bits per pixel for each image, allowing a single image to reference its own palette of up to 256 different colors chosen from the 24-bit RGB color space.
