It is called Icon Library (.ICL) and its sole purpose is to have multiple icons in one file. There is one more file format related to icons. Icon editors are usually able to extract icons from applications. This option is used quite often by application developers. Icons can also be embedded inside an application (.EXE), application extension (.DLL), or other executable file. Microsoft also recommends how the images should be ordered inside an icon. A file in this format holds all icon images. There is a standard file format for icons in Windows. If an image format is missing, Windows displays the nearest existing image. 16M colors (XP): Displayed by Windows XP if screen is 16M or more.256 colors: Displayed by Windows if the screen is 64K or 16M colors. 16 colors: Displayed by Windows if the screen is 16 or 256 colors.48x48: Displayed in Windows XP Explorer and system lists.32x32: Displayed on desktop, by Windows Explorer.24x24: Displayed in Windows XP start menu.16x16: Displayed in taskbar, windows upper-left corner, detailed lists.How does Windows use the various sizes and color depths? It is very important to create several image formats in an icon (especially if you whish to redistribute it) in order to be compatible with all screen configurations. Windows defines standard sizes (16x16, 32x32, 48x48) and standard color depths (16 colors, 256 colors, 16.8M colors), that should be present in any general-purpose icon. They have different sizes (or resolutions) and color depths. We have already mentioned in previous paragraph, that an icon is composed of several images. Transparent pixels are usually represented using chessboard pattern in icon editors. When a pixel is transparent, background is displayed on that spot. But icons always support per-pixel transparency, which means that any pixel can be marked either transparent or opaque. Internally, the icon still has a rectangular shape, just like an image. When you put an icon on your desktop, it appears to have arbitrary shape and you can see background around that shape. Images usually have rectangular shape, icons on the other hand do not. There are multiple images inside an icon, each optimized for best experience under specific circumstances. Icon should look good on high-resolution LCD as well as on a ten years old monochromatic monitor. This is because icon must be usable under wide variety of conditions. Icon is composed of arbitrary number of images. It is stored using one of the standard formats (BMP, PNG, GIF, JPEG, TIFF. It may have arbitrary size, resolution and color depth. For now, let's get back to year 2005, where icons and images are closest friends.Ī computer image is a raster (composed of pixels) or vector (composed of lines, rectangles, circles, etc.) picture. Icons would still be graphical symbols, but not images anymore. In future version of your operating system, icons may be using animations or even 3D models. But this could, and probably would change. An icon (graphical symbol) can easily be represented by an image. But then there are shoes that are not made of leather.
