Windows bitmap, a very similar file format.It is unknown if the various Windows operating system versions contain logic to infer the bit depth for all possibilities if this value is set to zero. If the bitmap is PNG compressed, the bits per pixel are stored within the PNG data. ↑ Note: The bits per pixel might be set to zero, but can be inferred from the other data specifically, if the bitmap is not PNG compressed, then the bits per pixel can be calculated based on the length of the bitmap data relative to the size of the image.It is unknown if the various Windows operating system versions are resilient to different color plane values. ↑ Note: Setting the color planes to 0 or 1 is treated equivalently by the operating system, but if the color planes are set higher than 1, this value should be multiplied by the bits per pixel to determine the final color depth of the image.It appears that the operating system ignores this value altogether. ↑ Note: Although Microsoft's technical documentation states that this value must be zero, the icon encoder built into.

The full set of standard icon sizes which should be provided for full Windows Vista compatibility: Recommended icon sizes for Windows Vista compatibility ICO format, should be 0 or 1, or the X hotspot when in. The actual 'data' for the first image in old AND/XOR DIB format or newer PNGĬolor count, should be 0 if more than 256 colorsĬolor planes when in. Stores general information about every image in the file. Stores general information about the ICO file. ICO files can be edited or exported with a number of graphics programs.Īll values are represented in little-endian (Intel standard) format. The Windows Vista graphical shell supports 'zooming' the display in and out as a result, more icon formats (including the larger, 256×256 format) are recommended. It is recommended that all 256×256 icons should be stored in the ICO file in PNG format to reduce the overall size of the file. The PNG format encodes the image transparency data directly it contains neither the XOR nor the AND bitmap data of the other icon image formats. Windows Vista added support for 256×256 pixel icon images, and supports (but does not require) the compressed PNG format for that size. Windows XP also adds the ability to display icons at up to 96×96 pixel resolution in the graphical shell however, Microsoft only recommended icon sizes up to 48×48 pixels, so larger icon sizes are uncommon. As the AND bitmap is no longer used, these icon images contain only XOR bitmap data. Windows XP adds support for 32-bit color depth icon images, with transparency taken from the alpha channel of the image, allowing semitransparent areas like shadows and anti-aliased edges. This allows for transparent areas in the image but also allows for inverting the background and other tricks. The XOR bitmap is then applied using XOR.

The AND bitmap is 1 bit per pixel and is applied first to decide which areas of the image are affected by the background. Icon image data was always made up of two bitmaps: the AND bitmap and the XOR bitmap. Commonly an icon file would contain both 16x16 and 32x32 (for the start menu and folder 'large icons' view) and 16x16 (for window title bars, submenus of the start menu and folder small icons, list and details views). Prior to Windows XP, icon images could be any size from 1×1 pixel up to 255×255 pixels (including non-square sizes), and 4-, 8-, 16-, or 24-bit color depth. Originally 32×32 pixels square and using 16 colors, more recent versions of Microsoft Windows support icons at multiple sizes and color depths. Icon sizes, color depths, and transparency data
