#include "Ltwrappr.h"

L_INT LRasterPaint::GetProperty(nGroup, pProperty)

PAINTGROUP nGroup;	pointer to a paint handle
L_VOID *pProperty;	pointer to a PAINTXXX structure

Gets the specified paint properties.

Parameter	Description
nGroup	Indicates the paint properties to get and the structure pointed to by pProperty. Possible values are:
	Value	Meaning
	PAINT_GROUP_BRUSH	Gets the Paintbrush properties. pProperty points to a PAINTBRUSH structure.
	PAINT_GROUP_SHAPE	Gets the Paint shape properties. pProperty points to a PAINTSHAPE structure.
	PAINT_GROUP_REGION	Gets the Paint region properties. pProperty points to a PAINTREGION structure.
	PAINT_GROUP_FILL	Gets the Paint fill properties. pProperty points to a PAINTFILL structure.
	PAINT_GROUP_TEXT	Gets the Paint fill properties. pProperty points to a PAINTTEXT structure.
pProperty	Pointer to a PAINTXXX structure to be updated with the specified property values. The type of structure that this parameter points to is indicated by the nGroup parameter.
