Graphic File Types

A bitmap (or raster) image is one of the two major graphic types (the other being vector). Bitmap- based images are comprised of in a grid. Each or "" in the image contains information about the color to be displayed. Bitmap images have a fixed resolution and cannot be resized without losing image quality. Common bitmap-based formats are BMP, TIFF JPEG, GIF, PNG, and EPS. Most bitmap images can be converted to other bitmap-based formats very easily. Bitmap images tend to have much large file sizes than and they are often compressed to reduce their size.

BMP – Abbreviation for the standard Bit-Mapped graphic format. BMP files store graphics in a format called device-independent bitmap (DIB).

TIFF -- Acronym for Tagged Image File Format, one of the most widely supported file formats for storing bit-mapped images on personal computers. TIFF graphics can be any resolution, and they can be , gray-scaled, or color. Files in TIFF format often end with a .tif extension

JPEG/JPG -- Short for Joint Photographic Experts Group, the original name of the committee that wrote the standard. JPG is one of the supported on the Web. JPG is a technique that is designed to compress color and continuous-tone images. The information that is discarded in the compression is information that the human eye cannot detect. JPG images support 16 million colors and are best suited for photographs and complex graphics. The user typically has to compromise on either the quality of the image or the size of the file. JPG does not work well on line drawings, lettering or simple graphics because there is not a lot of the image that can be thrown out in the lossy process, so the image loses clarity and sharpness. GIF -- Abbreviation for Graphics Interchange Format, another of the graphics formats supported by the Web. Unlike JPG, the GIF format is a technique and it supports only 256 colors. GIF is better than JPG for images with only a few distinct colors, such as line drawings, black and white images and small text that is only a few pixels high. With an animation editor, GIF images can be put together for animated images. GIF also supports , where the background color can be set to transparent in order to let the color on the underlying Web page to show through. The compression algorithm used in the GIF format is owned by Unisys, and companies that use the algorithm are supposed to license the use from Unisys.

PNG -- Short for Portable Network Graphics, the third graphics standard supported by the Web (though not supported by all browsers). PNG was developed as a patent-free answer to the GIF format but is also an improvement on the GIF technique. An image in a lossless PNG file can be 5%- 25% more compressed than a GIF file of the same image. PNG builds on the idea of transparency in GIF images and allows the control of the degree of transparency, known as opacity. Saving, restoring and re-saving a PNG image will not degrade its quality. PNG does not support animation like GIF does. *Unisys announced in 1995 that it would require people to pay licensing fees in order to use GIF. This does not mean that anyone who creates or uses a GIF image has to pay for it. Authors writing programs that output GIF images are subject to licensing fees.

EPS – Abbreviation for Encapsulated PostScript. Pronounced as separate letters, EPS is the graphics file format used by the PostScript language. PostScript is primarily a language for printing documents on laser printers, but it can be adapted to produce images on other types of devices. PostScript is the standard for desktop publishing because it is supported by image setters, the very high-resolution printers used by service bureaus to produce camera-ready copy.
