Description
The routine gSetLineColour() selects a colour for subsequent graphical output. The argument col can be an index in the current GINO colour table or (on a true colour device) a 24bit RGB triplet returned by the function gTrueCol().
The colour index values/constants described above represent the initial setting of the GINO colour table, which may however be modified using one of the colour definition routines gDefineRGB(), gDefineHSV() or gDefineHLS(). Whether a colour actually appears on a device depends on the device's hardware capabilities.
The background colour is selected by setting col=GBACKGROUND. Graphical output may be erased from the picture by redrawing it with the background colour, provided that this is supported by the device.
If a negative value is passed in col, a warning message is output and the absolute value of col is used. When col is outside the range of colours of the device, a default colour is selected. A call to gEnqSelectedPen() returns the colour actually provided.
