Camelot: Kernel/attrmgr.cpp File Reference

static function called by UpdateForDeletedColours. Ensures that the given DocColour is a safe colour to use (does not reference a deleted IndexedColour). If it needs to be fixed, a default colour will be found (or created if necessary) in the given colour list and the colour will be made to reference the new default.

NewDefault - NULL, or a pointer to the default colour returned from a previous call to this function. This makes fixing several colours in a row a lot more efficient.

The NewDefault value should be set to NULL before the first call to this function. On subsequent calls, pass in the same value; if a change is made, this allows the system to be more efficient, and guarantees all changed colours reference the correct default colour.

#define	COL_ACCURACY (0.001)
	Used in initialisation of default attributes, and when ensuring no current attributes use deleted colour(s), to find a suitable default colour to use. Two default colours are currently provided, accessed by passing in NameResID of _R(IDS_WHITENAME), _R(IDS_BLACKNAME), in order to get the default white or black colour respectively.

static BOOL	UpdateDeletedColour (ColourList ColList, DocColour TheColour, IndexedColour **NewDefault)
