LOGBRUSH structure (wingdi.h)
The LOGBRUSH structure defines the style, color, and pattern of a physical brush. It is used by the CreateBrushIndirect and ExtCreatePen functions.
Syntax
typedef struct tagLOGBRUSH {
UINT lbStyle;
COLORREF lbColor;
ULONG_PTR lbHatch;
} LOGBRUSH, *PLOGBRUSH, *NPLOGBRUSH, *LPLOGBRUSH;
Members
lbStyle
The brush style. The lbStyle member must be one of the following styles.
Value | Meaning |
---|---|
BS_DIBPATTERN | A pattern brush defined by a device-independent bitmap (DIB) specification. If lbStyle is BS_DIBPATTERN, the lbHatch member contains a handle to a packed DIB. For more information, see discussion in lbHatch. |
BS_DIBPATTERN8X8 | See BS_DIBPATTERN. |
BS_DIBPATTERNPT | A pattern brush defined by a device-independent bitmap (DIB) specification. If lbStyle is BS_DIBPATTERNPT, the lbHatch member contains a pointer to a packed DIB. For more information, see discussion in lbHatch. |
BS_HATCHED | Hatched brush. |
BS_HOLLOW | Hollow brush. |
BS_NULL | Same as BS_HOLLOW. |
BS_PATTERN | Pattern brush defined by a memory bitmap. |
BS_PATTERN8X8 | See BS_PATTERN. |
BS_SOLID | Solid brush. |
lbColor
The color in which the brush is to be drawn. If lbStyle is the BS_HOLLOW or BS_PATTERN style, lbColor is ignored.
If lbStyle is BS_DIBPATTERN or BS_DIBPATTERNPT, the low-order word of lbColor specifies whether the bmiColors members of the BITMAPINFO structure contain explicit red, green, blue (RGB) values or indexes into the currently realized logical palette. The lbColor member must be one of the following values.
Value | Meaning |
---|---|
DIB_PAL_COLORS | The color table consists of an array of 16-bit indexes into the currently realized logical palette. |
DIB_RGB_COLORS | The color table contains literal RGB values. |
If lbStyle is BS_HATCHED or BS_SOLID, lbColor is a COLORREF color value. To create a COLORREF color value, use the RGB macro.
lbHatch
A hatch style. The meaning depends on the brush style defined by lbStyle.
If lbStyle is BS_DIBPATTERN, the lbHatch member contains a handle to a packed DIB. To obtain this handle, an application calls the GlobalAlloc function with GMEM_MOVEABLE (or LocalAlloc with LMEM_MOVEABLE) to allocate a block of memory and then fills the memory with the packed DIB. A packed DIB consists of a BITMAPINFO structure immediately followed by the array of bytes that define the pixels of the bitmap.
If lbStyle is BS_DIBPATTERNPT, the lbHatch member contains a pointer to a packed DIB. The pointer derives from the memory block created by LocalAlloc with LMEM_FIXED set or by GlobalAlloc with GMEM_FIXED set, or it is the pointer returned by a call like LocalLock (handle_to_the_dib). A packed DIB consists of a BITMAPINFO structure immediately followed by the array of bytes that define the pixels of the bitmap.
If lbStyle is BS_HATCHED, the lbHatch 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 lbStyle is BS_PATTERN, lbHatch is a handle to the bitmap that defines the pattern. The bitmap cannot be a DIB section bitmap, which is created by the CreateDIBSection function.
If lbStyle is BS_SOLID or BS_HOLLOW, lbHatch is ignored.
Remarks
Although lbColor controls the foreground color of a hatch brush, the SetBkMode and SetBkColor functions control the background color.
