The PNG format (see below) was developed in 1995 as an intended replacement. Free Say what03 image. 0.00 s. SD. The image pixel data, scanned horizontally from top left, are converted by LZW encoding to codes that are then mapped into bytes for storing in the file. When 24-bit color became the norm palettes could instead be populated with the optimum colors for individual images. [37] Further patents were obtained in the United Kingdom, France, Germany, Italy, Japan and Canada. These are decoded to recover the pixel colors as shown below.

The data is stream-oriented, so the file offset of the start of each GCE depends on the length of preceding data. The indicator that an image is interlaced is a bit set in the corresponding Image Descriptor block. [37][41], The popularity of LZW led CompuServe to choose it as the compression technique for their version of GIF, developed in 1987. Simply packing a series of independent frame images into a composite animation tends to yield large file sizes. Within each frame the LZW-coded image data is arranged in sub-blocks of up to 255 bytes; the size of each sub-block is declared by the byte that precedes it. Portable Network Graphics (PNG) was designed as a replacement for GIF in order to avoid infringement of Unisys' patent on the LZW compression technique.

[1] It has since come into widespread usage on the World Wide Web due to its wide support and portability between applications and operating systems. [59][60] APNG is currently supported by all major web browsers including Chrome since version 59.0 and Opera and Firefox and Edge. The Graphics Interchange Format ( GIF / dʒɪf / JIF or / ɡɪf / GHIF) is a bitmap image format that was developed by a team at the online services provider CompuServe led by American computer scientist Steve Wilhite on 15 June 1987.
