Unloading icons into files

CgIcon objects are unloaded into files using the same methods as for images. However, as with the icon load methods, an array of CgIcons is given, rather than a single CgIcon.

The following code unloads a single icon into a file in the Windows ICO format. It assumes that the iconToUnload method answers the CgIcon to unload.

| icons format |

icons := Array with: self iconToUnload.

format := CgWinICOFileFormat new.

(format unload: icons intoFile: 'icon-out.ico')

ifFalse: [self error: 'Error unloading icon']
