PAINTFILL

Summary

The PAINTFILL structure holds information used to fill an area.

Syntax

typedef struct _PAINTFILL 
{ 
   L_INT nSize; 
   L_UINT32 dwMask; 
   PAINTFILLSTYLE nStyle; 
   COLORREF crSolidFillColor; 
   pBITMAPHANDLE pBackgroundTileBitmap; 
   PAINTFILLGRADIENTSTYLE nGradientStyle; 
   COLORREF crGradientStartColor; 
   COLORREF crGradientEndColor; 
   L_UINT uGradientSteps; 
   COLORREF crUpperTolerance; 
   COLORREF crLowerTolerance; 
   L_INT nOpacity; 
   pBITMAPHANDLE pTexture; 
} PAINTFILL,  *pPAINTFILL; 

Members

nSize

Size of this structure.

dwMask

Flags that indicate which structure members contain valid information. Possible values are:

The values can be combined using the bit-wise OR operator ( | )

nStyle

An enumerated type that indicates the fill style. For a list of possible values, refer to PAINTFILLSTYLE.

crSolidFillColor

COLORREF value that specifies the color to use when nStyle is PAINT_FILL_STYLE_SOLID.

pBackgroundTileBitmap

Pointer to the bitmap handle referencing the bitmap to be used for filling, when nStyle is PAINT_FILL_STYLE_TILEDIMAGE. The BITMAPHANDLE pointer, should still be valid after setting this field.

nGradientStyle

An enumerated type that indicates the background gradient fill style. For a list of possible values, refer to PAINTFILLGRADIENTSTYLE.

crGradientStartColor

The COLORREF value that specifies the color to use as the starting color for the gradient fill.

crGradientEndColor

The COLORREF value that specifies the color to use as the ending color for the gradient fill.

uGradientSteps

Number of gradient fill steps. Valid values are 2 to 255.

crUpperTolerance

COLORREF value that contains the amount of upper variance allowed from the selected color. Valid values are between 0 and 255.

crLowerTolerance

COLORREF value that contains the amount of lower variance allowed from the selected color. Valid values are between 0 and 255.

nOpacity

Value indicating the transparency of the fill when combined with the painting canvas. Valid values are 0 to 255. A color or an image with an opacity of 255 is transparent. A color or an image with an opacity of 0 is completely opaque (solid).

pTexture

Pointer to the bitmap handle referencing the bitmap that will simulate paper texture. This gives the appearance of painting on paper having that texture. The BITMAPHANDLE pointer, should still be valid after setting this field.

Comments

The default values for this structure are:

nSize = sizeof (PAINTFILL)   
nStyle = PAINT_FILL_STYLE_SOLID   
crSolidFillColor = RGB (255, 255, 255)   
pBackgroundTileBitmap = NULL   
nGradientStyle = PAINT_FILL_GRADIENT_STYLE_RECTANGLE_TO_C   
nGradientStartColor = RGB (0, 0, 0)   
nGradientEndColor = RGB (255, 255, 255)   
uGradientSteps = 255   
crUpperTolerance = RGB (0, 0, 0)   
crLowerTolerance = RGB (0, 0, 0)   
nOpacity = 0   
pTexture = NULL 

pPAINTFILL is a pointer to a PAINTFILL structure.
