Developers can change the default Director MX 2004 projector icon by creating and using a custom icon.
The first thing that Director checks from the icon file during publishing is a resource fork with icon resources. Director transfers the resources it finds to the projector. Director just transfers the first such resource found and renumbers the resources as needed. Here is the list of icon resources:
- icl4
- icl8
- icm#
- icm4
- icm8
- ICN#
- ics#
- ics4
- ics8
Macintosh OS X projectors should have a data fork containing data in the 'icns' format. This is the standard icon format for Macintosh OS X style icons. Usually these files are identified by a .icns extension on the file name. This data is added as a 'icns' resource to the projector.
Windows icons should have an .ICO filename extension, which contains icon data in multiple resolutions. If the ICO file does not contain all of the icons, only some of the icons will be updated. This allows a projector application to display different icons depending on what icon size Windows chooses to display. The same thing can be done on Macintosh OS 9 if only some of the icon resources are updated. A windows projector contains the following ICON formats.
- 48x48-pixel, 4-Bit Color
- 32x32-pixel, 4-Bit Color
- 16x16-pixel, 4-Bit Color
- 48x48-pixel, 8-Bit Color
- 32x32-pixel, 8-Bit Color
- 16x16-pixel, 8-Bit Color
- 48x48-pixel, 32-Bit Color
- 32x32-pixel, 32-Bit Color
- 16x16-pixel, 32-Bit Color
Note: Custom application icons cannot be created for a cross platform projector. As a workaround, use a resource editor to change the icon of the cross platform projector.
