![]() ![]() Many older browsers do not yet support the PNG file format. The lossless PNG format is best suited for editing pictures, and the lossy formats like JPG are best for storage because of smaller file size. PNG excels when the image has large areas of uniform color. The PNG file format supports true color (16 million colors) whereas the GIF file format only 256 colors. The PNG (Portable Network Graphics) file format does almost everything that the GIF format does and does it better. It is not at all suitable for photographs. The GIF format does well with images having 256 colors or fewer. But, is being superseded by the PNG format. It is still used extensively on the Internet because of the great reservoir of GIF images available, and because it supports animation. As a result, it is not used for photographic work. The GIF file format is limited to an 8-bit pallete (256 colors). Because of the compression algorithm “artifacts” (blemishes) sometimes appear. These files are best kept in original form. But, JPEG files do suffer generational degradation when repeatedly edited and saved. Fortunately, the compression in most cases does not distract noticeably from the image. Nearly all digital cameras have the option to save images in JPEG format, some at different compression levels, such as “fine” and “standard.” The JPEG format supports full color and produces relatively small file sizes. The DOS filename extension is JPG, although other operating systems may use JPEG. ![]() VisiPics uses the ImageMagick libraries to load pictures, for more informations: The JPEG (Joint Photographic Experts Group) image files are a lossy format.

It then applies five image comparison filters in order to measure how close pairs of images on the hard drive are.
