DIB_Brush

Specifies the attributes, mask, and bits of brushes for the DIB engine. There are separate structures for 1bpp, 4bpp, 8bpp, 16bpp, 24bpp, and 32bpp displays.

Members

dpxBrushFlags

Flags describing the brush. Must be one of the following.

COLORSOLID	Color part is solid.
MONOSOLID	Monochrome part is solid.
PATTERNMONO	Pattern brush came from a monochrome bitmap.
MONOVALID	Monochrome part is valid.
MASKVALID	Transparency mask part is valid.
PRIVATEDATA	Vendor specific bit for pens and brushes.

dpxBrushBpp

The number of bits per pixel. Must be 1, 4, 8, 16, 24, or 32.

dpxBrushStyle

Style of the brush. Must be one of the following.

Value	Meaning
BS_SOLID (0)	Solid brush.
BS_NULL (1)	Same as BS_HOLLOW.
BS_HOLLOW (1)	Hollow brush.
BS_HATCHED (2)	Hatched brush.
BS_PATTERN (3)	Pattern brush defined by a memory bitmap.
BS_INDEXED (4)	Indexed brush.
BS_DIBPATTERN (5)	A pattern brush defined by a device-independent bitmap (DIB) specification.
BS_DIBPATTERNPT (6)	A pattern brush defined by a device-independent bitmap (DIB) specification.
BS_PATTERN8X8 (7)	Same meaning as BS_PATTERN.
BS_DIBPATTERN8X8 (8)	Same meaning as BS_DIBPATTERN.

dpxFgColor

Foreground color. For the dp8FgColor member of DIB_Brush8, the color is a logical color if the brush style is BS_SOLID or BS_PATTERN. If the brush style is BS_HATCHED, dp8FgColor contains a physical color.

dpxHatch

Specifies a hatch style. The meaning depends on the brush style defined by dpxBrushStyle.

If dpxBrushStyle is BS_DIBPATTERN, the dpxHatch member contains a handle to a packed DIB. If dpxBrushStyle is BS_DIBPATTERNPT, the dpxHatch member contains a pointer to a packed DIB.

If dpxBrushStyle is BS_HATCHED, the dpxHatch member specifies the orientation of the lines used to create the hatch. It can be one of the following values.

Value	Meaning
HS_BDIAGONAL	A 45-degree upward, left-to-right hatch
HS_CROSS	Horizontal and vertical cross-hatch
HS_DIAGCROSS	45-degree crosshatch
HS_FDIAGONAL	A 45-degree downward, left-to-right hatch
HS_HORIZONTAL	Horizontal hatch
HS_VERTICAL	Vertical hatch

If dpxBrushStyle is BS_PATTERN, dpxHatch is a handle to the bitmap that defines the pattern.

If dpxBrushStyle is BS_SOLID or BS_HOLLOW, dpxHatch is ignored.

dpxBgColor

Background color. This member is only used with BS_HATCHED style brushes and it is a physical color.

dpxBrushMono

Bits describing monochrome version of the brush.

dpxBrushMask

Bits describing the transparency mask (hatch pattern) portion of the brush.

dpxBrushBits

The bits describing the brush. The size is 8 rows by 8 columns with either 1, 4, 8, 16, 24, or 32 bits per pixel.
