Remarks

getfillsettings fills in the fillsettingstype structure pointed to by fillinfo with information about the current fill pattern and fill color. The fillsettingstype structure is defined in graphics.h as follows:

struct fillsettingstype {

int pattern;	/* current fill pattern */
int color; }; The functions bar, barSd, fillpoly, floodfill, and pieslice all fill an area with the current fill pattern in the current fill color. There are 11 predefined fill pattern styles (such as solid, Crosshatch, dotted, and so on). Symbolic names for the predefined patterns are provided by the enumerated type fil!_patterns in graphics.h (see the following table). In addition, you can define your own fill pattern.	/* current fill color */

If pattern equals 12 (USER_FILL), then a user-defined fill pattern is being used; otherw^ise, pattern gives the number of a predefined pattern.

The enumerated type filljpatterns, defined in graphics.h, gives names for the predefined fill patterns, plus an indicator for a user-defined pattern.

Name	Value	Description
EMPTY FILL	0	Fill with background color
SOLID FILL	1	Solid fill
LINE FILL	2	Fill with
LTSLASH FILL	3	Fill with///
SLASH FILL	4	Fill with ///, thick lines
BKSLASH FILL	5	Fill with \\\, thick lines
LTBKSLASH	FILL	6	Fill with \\\
HATCH	FILL	7	Light hatch fill
XHATCH	FILL	8	Heavy Crosshatch fill
INTERLEAVE	FILL	9	Interleaving line fill
WIDE DOT FILL	10	Widely spaced dot fill
CLOSE DOT FILL	11	Closely spaced dot fill
USER FILL	12	User-defined fill pattern

All but EMPTY_FILL	fill with the current fill color; EMPTY_FILL	uses the

current background color.

Return value

None.
