Many image formats have identifiers that uniquely identify a particular image format. For example, the GIF image format always begins with GIF8 as the first 4 characters of the image. ImageMagick uses this information to quickly determine the type of image it is dealing with when it reads an image. --> <magicmap> <!-- <magic name="GIF" offset="0" target="GIF8"/> --> <!-- <magic name="JPEG" offset="0" target="\377\330\377"/> --> <!-- <magic name="PNG" offset="0" target="\211PNG\r\n\032\n"/> --> <!-- <magic name="TIFF" offset="0" target="\115\115\000\052"/> --> </magicmap>
