Introduction The ART format (file extension ".art") holds a single still image that has been highly compressed. The format was designed to facilitate the quick downloading of images, among other things. The ICO file format is an image file format for computer icons in Microsoft Windows. ICO files contain one or more small images at multiple sizes and color depths, such that they may be scaled appropriately. In Windows, all executables that display an icon to the user, on the desktop, in the Start Menu, or in Windows Explorer, must carry the icon in ICO format.
Technical details When an image is converted to the ART format, the image is analyzed and the software decides what compression technique would be best. The ART format has similarities to the progressive JPEG format, and certain attributes of the ART format can lead to image quality being sacrificed for the sake of image compression. An ICO file is made up of an ICONDIR ("Icon directory") structure, containing an ICONDIRENTRY structure for each image in the file, followed by a contiguous block of all image bitmap data (which may be in either Windows BMP format, excluding the BITMAPFILEHEADER structure, or in PNG format, stored in its entirety).
