The GIF images is popular again and one can say they are having a period of renascence. I spent this evening on Tumblr to get you the best new GIF images.
The word GIF stands for Graphics Interchange Format. The format supports up to 8 bits per pixel thus allowing a single image to reference a palette of up to 256 distinct colours.
The colors are chosen from the 24-bit RGB colour space. It also supports animations and allows a separate palette of 256 colours for each frame.
The colour limitation makes the GIF format unsuitable for reproducing colour photographs and other images with continuous colour, but it is well-suited for simpler images such as graphics or logos with solid areas of colour.
GIF is palette-based: the colours used in an image in the file have their RGB values defined in a palette table that can hold up to 256 entries, and the data for the image refer to the colours by their indices (0–255) in the palette table.
The colour definitions in the palette can be drawn from a colour space of millions of shades (224 shades, 8 bits for each primary), but the maximum number of colours a frame can use is 256.
This limitation seemed reasonable when GIF was developed because few people could afford the hardware to display more colours simultaneously. Simple graphics, line drawings, cartoons, and grey-scale photographs typically need fewer than 256 colours.
