Setting colors in PNG graphics

To set the colors in PNG graphics, follow these steps:

1. Click the FrameMaker and Generated Files folder. (If you want to set a custom mapping for a single file, click that file instead.)
2. Select Project » Properties, or right-click and select Properties from the pop-up menu.
3. Click the Macros tab.
4. In the Macro Name drop-down list, select UMGraphicPNGColors. The default for the UMGraphicPNGColors user macro-256-is displayed as grayed-out text. The 256 indicates that the graphic uses the palette with 256 colors.
5. Click the Let me override the value for this macro when converting this file check box. The default becomes black to indicate you can change it.
6. In the Macro Value field, type a new value over the default. You change the default to one of the following values:
   • mono-black and white
   • gray-a grayscale palette
   • 16-a palette with 16 colors
   • 256-a palette with 256 colors
   • 16m-a palette with 16 million colors
7. Click OK to save your changes.
8. Regenerate your project (or the graphic you want to change) to see the new graphic output.
