The Graphics Interchange Format, one of the most popular standardized formats for storing graphic data in binary computer files. The standard has been revised several times, and includes provisions for interlacing and animating images. Its disadvantage is that it can store only colors. Meaning JPEG. Computers An image stored in GIF format, or the file in which the image is stored; as, he sent three GIF's with lovely pictures of his children.
The Graphics Interchange Format is a bitmap image format that was introduced by CompuServe in and has since come into widespread usage on the World Wide Web due to its hot cuckold captions support and portability.
A GIF marked 87a may contain extension blocks; the intent is that a decoder can read and display the file without the features covered in extensions it does not understand. The full detail of the file format is covered in the GIF specification. Gif is palette-based: the colors used kobra paige nude an image a frame in the file have their RGB values defined in a palette table that can hold up to entries, and the data for the image refer to the colors by their indices 0— in the palette table.
The color definitions in the palette can be meaning from a color space of gif of shades 2 24 shades, 8 bits for each primarybut the maximum number of colors a meaning can use is This limitation seemed reasonable when GIF was developed because few people could afford the hardware to display more colors simultaneously.
Simple graphics, line drawings, cartoons, and grey-scale photographs typically need fewer than colors.
Gif frame can designate one index as a "transparent background color": any pixel assigned this index takes on the color of the pixel in the same position from the background, which may have been determined by a previous frame of animation. Many techniques, collectively called ditheringhave been developed to approximate a wider range nudes in sex acts colors with a small color palette by using pixels of two or more colors to approximate in-between colors.
These techniques sacrifice spatial resolution to approximate deeper color resolution. This is often not an ideal solution for GIF images, gif because the loss of spatial resolution typically makes an image look fuzzy on the screen, and because the dithering patterns often interfere with the compressibility of the image data, working against GIF's main purpose. In the early days of graphical web browsers [ when? When bit color became the norm palettes could instead be populated with the optimum colors for individual images.
A small color table may suffice for small images, and keeping the color table small allows the file to be downloaded faster. Both the 87a and 89a specifications allow color tables meaning 2 n colors for any n from 1 meaning 8.
Most gif applications will read and display GIF images with any of these table sizes; but some do not support all sizes when creating images. Tables of 2, 16, and colors are widely supported. Although GIF is almost never used for true color images, it is possible to do so. Alternatively, the GIF89a specification introduced the idea of a "transparent" color where each image block can include its own palette of visible colors plus one transparent color.
A complete image can be created by layering image blocks with the visible portion of each layer showing through the transparent portions of the layers above. To render a full-color image as a GIF, the original image must be broken down into smaller regions having no more than or different colors. Each of these regions is then stored as a separate image block with its own local palette and meaning the image blocks are displayed together either by tiling or great girl porn layering partially transparent image blocks the complete, full-color image appears.
For example, breaking an image into tiles of 16 by 16 pixels pixels in total ensures that no tile has more than the local palette limit of colors, although larger tiles may be used pictures of anorexic girls naked similar colors merged resulting in some loss of color information.
Since each image block requires its own local color table, a GIF file having lots of image blocks can be very large, limiting the usefulness of full-color GIFs. Many rendering programs interpret tiles or layers as animation frames and display them in sequence as an endless animation  with most web browsers automatically displaying the frames with a delay time of 0.
Microsoft Paint saves a small black-and-white image as the following GIF file. Paint does not make optimal use of GIF; due to the unnecessarily gif color table storing a full colors instead of the used 2 and symbol width, this GIF file is not an efficient representation of the pixel image illustrated meaning above. Although the Graphics Control Extension block declares meaning index 16 hexadecimal 10 to be transparent, that index is not used in the image.
The only color indexes appearing in the image data are decimal 40 andwhich the Global Color Table maps to black and white, respectively. Note that the hex numbers in the following tables are in little-endian byte order, as the format specification prescribes.
The image pixel data, scanned horizontally from top left, are converted gif LZW encoding to codes that are then mapped into bytes for storing in the file.

The pixel codes typically don't match the 8-bit size of the bytes, so the gif are packed into bytes by a "little-Endian" scheme: the least significant bit of the first code is stored in the least significant bit of the first byte, higher order bits of the code into higher order bits of the byte, spilling over into the low order bits of the next byte as necessary.

|lara dutta xxx hot||The format supports up to 8 bits per pixel for each image, allowing a single image to reference its own palette of up to different colors jiah khan suicide pics from the bit RGB color space. It also supports animations and allows a separate palette of up to colors for each frame. These palette limitations make GIF less suitable for reproducing color photographs and other images with color gradients, but it is well-suited for simpler images such as graphics or logos with solid areas of color. GIF images are compressed using the Lempel—Ziv—Welch LZW lossless meaning compression technique to reduce the file size without degrading the visual gif. This compression technique was patented in Controversy over the licensing agreement between the software patent holder, Unisysand CompuServe in spurred the development of the Portable Network Graphics PNG standard. By all the relevant patents had expired.|

However, the 89a format also includes support for animation delays. Since GIFs may only contain colors, they are not meaning for storing digital photos, such as those captured with a digital camera. Even when using gif custom color palette and applying dithering to smooth out the image, photos saved in the GIF format often look grainy and unrealistic.|
