Foreground Color All PCL marking entities utilize “foreground” color, which is selected from the current palette using the Foreground Color command (?*v#S). Foreground color interacts with raster color depending on the print model commands in effect. Foreground Color Command The Foreground Color command sets the foreground color to the specified index of the current palette. ?*v#S # = Index number into current palette Default = 0 Range = 0 to 2 (current palette size) – 1 Specified values that are out-of-range of the current palette are mapped into a new index as follows: Index = Specified foreground index modulo palette size For example, specifying a foreground color index of 10 when the current palette size is 8 maps to 10 modulo 8, which is equal to 2. If the current palette was created under HP-GL/2, the index is mapped according to the HP-GL/2 mapping function. Foreground color affects the following PCL page marking primitives: Text characters (they change to the foreground color, including underlining) Solid or monochrome patterned rectangular area fills (rules) Monochrome patterns (except HP-GL/2) Raster images The following are not affected: User-defined color patterns (format 1 download patterns) HP-GL/2 marking primitives (HP-GL/2 uses “selected pen”, but ignores foreground color) EN Using Palettes 3-17
