PAINTREGION

typedef struct _PAINTREGION
{
   L_INT      nSize;
   L_UINT32   dwMask;
   COLORREF   crUpperTolerance;

The PAINTREGION structure holds information used for creating a region.

Member	Description
nSize	Size of this structure.
dwMask	Flags that indicate which members contain valid information for the structure. Possible values are:
	Value	Meaning
	PRF_ALL	All the fields contain valid data.
	PRF_UPPERTOLERANCE	The crUpperTolerance field contains valid data.
	PRF_LOWERTOLERANCE	The crLowerTolerance field contains valid data.
	PRF_ROUNDRECTELLIPSEWIDTH	The nRoundRectEllipseWidth field contains valid data.
	PRF_ROUNDRECTELLIPSEHEIGHT	The nRoundRectEllipseHeight field contains valid data.
	The values can be combined using the bit-wise OR operator ( \| )
crUpperTolerance	COLORREF value that contains the amount of upper variance allowed from the selected color. Valid values are between 0 and 255. The values of R, G and B will be used to check the tolerance.
crLowerTolerance	COLORREF value that contains the amount of lower variance allowed from the selected color. Valid values are between 0 and 255. The values of R, G and B will be used to check the tolerance.
nRoundRectEllipseWidth	Value indicating the width, in pixels, of the ellipse used to create a round rectangle region. Valid values are 0 to 500.
nRoundRectEllipseHeight	Value indicating the height, in pixels, of the ellipse used to create a round rectangle region. Valid values are 0 to 500.

Comments

The default values for this structure are:

nSize = sizeof (PAINTREGION)
crUpperTolerance = RGB (0, 0, 0)
crLowerTolerance = RGB (0, 0, 0)
nRoundRectEllipseWidth = 0
nRoundRectEllipseHeight = 0

pPAINTREGION is a pointer to a PAINTREGION structure.
