Function Reference


Saves a specified single or multiple icon (HICON) to the specified icon (.ico) file

#include <WinAPIGdi.au3>
_WinAPI_SaveHICONToFile ( $sFilePath, Const ByRef $vIcon [, $bCompress = 0 [, $iStart = 0 [, $iEnd = -1]]] )


$sFilePath The name of the .ico file in which to save the icon.
$vIcon Handle to the icon or array of the icon handles to be save.
$bCompress [optional] Specifies whether to use PNG compression for the 32 bits-per-pixel icons if its size exceed or
equal to 256x256 pixels (262144 bytes), valid values:
True - The icon will be saved as a PNG image.
False - The icon will be saved directly (Default).
$iStart [optional] The index of array to start saving at.
$iEnd [optional] The index of array to stop saving at.

Return Value

Success: 1.
Failure: 0 and sets the @error flag to non-zero.


This function works with 16, 24, and 32 bits-per-pixel icons. Since the icon handles always contains a device-depended
XOR bitmap (DDB), the resulting image that saved in .ico file may differ from the source image.

If the specified icon is a 32 bits-per-pixel icon, and uses the AND bitmask bitmap instead of alpha channel,
it will be converted to an icon with alpha channel (RGB + Alpha).

Note that the icons with PNG compression are supported starting only with Windows Vista. In addition,
not all applications can work with such icons.
