Colour Selection

Colour Mapping

Resource:
Command Line: -ic
Default Setting: on
Most workstations have only one hardware colour map, a physical register into which
colour values are written by the application program for display. As each application
will have its own set of colour values (called a virtual colour map), moving the
pointer into another window will cause the previous hardware colour map to be
overwritten by the virtual colour map of the newly selected window. As all windows
displayed on the screen share the same hardware colour map, the colours in other
windows will be changed accordingly. The setting of these commands determines
whether the application program overwrites the colour map or not.
Colour Mode
Resource:
Command Line: -cm
Default Setting: off (StaticColour mode selected)
The setting of these commands determines whether StaticColour or PseudoColour
visual mode is selected.
StaticColour visual is selected when PseudoColour is off (default), or +cm is
included in the command line. In this mode the nearest colour from a read-only
colour map is displayed. XOR functions and plane mask oriented commands may not
operate correctly in this mode but the display is consistent irrespective of pointer
context.
PseudoColour visual is selected when the resource is on, or -cm is included in the
command line. In this mode, XOR functions, colour map modifications and plane
mask orientated commands operate as on the DEC VT340 terminal, but displayed
colours may only be correct when the pointer is within the graphics window.
