Iconographer supports both the loading and the saving of icons in the .ico Windows format. The resulting files can then be transferred to a machine running Windows 9x/NT, where they can be used just like any other icon. To load a Windows icon, select the Windows option from the Format pop-up in the file open dialog (Open under the File menu). Once you select a file, it will be placed in an editor window, where you can work with it just like you would with any other icon. One thing to note is that the Windows icon format does not support 8-bit masking, thus any such data will be lost when saving.

Iconographer supports the loading of icons in the .tiff Mac OS X Server format when QuickTime 4.0 is installed. To load a Windows icon, select the Mac OS X Server option from the Format pop-up in the file open dialog (Open under the File menu). Once you select a file, it will be placed in an editor window, where you can work with it just like you would with any other icon. Saving of icons in this format will be present in a future version.
