A quick tour of the Color Mapping Rules dialog box (Maritime Charting)
Color mapping rules allow you to replace colors displayed on a map or chart with other colors during export to PDF using the Production PDF exporter. These rules specify an input color and a replacement output color. You can convert between colorspaces through the Color Mapping Rules dialog box. You access this dialog box from the Production tab on the Export Map dialog box.

The Color Mapping Rules dialog box with RGB input colors converted to CMYK output colors. |
注:Conversions between RGB and CMYK may appear inexact. Converting RGB to CMYK must convert 3 components representing color intensity to 4 that represent saturation percentage. Converting CMYK to RGB may result in data loss as RGB uses fewer color components to describe its color.
Once you have defined color mapping rules, you can save them to an .xml file. This allows you to share and reuse rules.
Color selection
Input colors can come from the map display. You can define your own input colors using the Input Color Selector dialog box. The Input Color Selector dialog box can create input colors in RGB or CMYK colorspaces only. You use the Output Color Selector dialog box to define output colors in RGB, CMYK, Spot, or All (typically used to define printer marks). The output color can also be defined to be a null color (no color). Null colors cannot be defined as input colors.
注:The Input Color Selector dialog box is accessed by double-clicking the Input cell in the Color Mapping Rules dialog box. Double-click in the Output cell to access the Output Color Selector dialog box.

The Color Mapping Rules dialog box context menu
The Color Mapping Rules dialog box has rows of colors and columns that contain descriptive information about those colors. Right-clicking any row displays a context menu. Holding down the Select or Ctrl keys when a row is selected allows multiple rows to be selected. Not all context menu commands are enabled or work when multiple rows are selected.
