Simple Color Mode The Simple Color command (?*r#U) specifies color selection from a fixed palette. RGB or CMY raster data must be sent by plane (?*b#V) as well as by row (?*b#W). The last plane in each row is sent using the ?*b#W command; all other planes are sent using the ?*b#V command. In Simple Color mode, the pixel encoding mode is always indexed planar. Simple Color Command The Simple Color command creates a fixed-size palette, whose color specification cannot be modified. ?*r#U # = –3 - 3 planes, device CMY palette 1 - Single plane K (Black) palette 3 - 3 planes, device RGB palette Default = 1 Range = –3, 1, 3 The absolute value of the value field specifies the number of planes per row of raster data to be sent. The number of entries in the new palette is 2 n , with index values 0 to 2 n – 1. For example, a 3-plane palette has 8 entries, with index numbers 0 to 7. This command destroys the active palette and creates a new palette, which becomes the active palette. When the Simple Color mode is active, PCL and HP-GL/2 commands that modify the palette are locked out (NP, PC, ?*v#A, ?*v#B, ?*v#C, ?*v#I). When a Simple Color palette is popped from the stack (?*p#P), it cannot be modified, and the pixel encoding mode reverts to indexed planar. A value field of 1 creates a 2-entry Black-and-White default palette. A value field of 3 creates an 8-entry Device RGB palette (compatible with a PCL Imaging Mode palette, but not an HP-GL/2 default (IN) palette). A value field of –3 creates an 8-entry palette in Device CMY color space. B-4 Using Color Modes (Color LaserJet, 5, 5M, DeskJet) EN
