LOGBRUSH Structure

  • 아티클

The LOGBRUSH structure defines the style, color, and pattern of a physical brush. It is used by the Windows CreateBrushIndirect and ExtCreatePen functions.

typedef struct tag LOGBRUSH { /* lb */
   UINT lbStyle;
   COLORREF lbColor;
   LONG lbHatch;
} LOGBRUSH;

Parameters

  • lbStyle
    Specifies the brush style. The lbStyle member must be one of the following styles:

    • 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.

    • 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.

    • BS_HATCHED   Hatched brush.

    • BS_HOLLOW   Hollow brush.

    • BS_NULL   Same as BS_HOLLOW.

    • BS_PATTERN   Pattern brush defined by a memory bitmap.

    • BS_SOLID   Solid brush.

  • lbColor
    Specifies 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_DIBPATTERNBT, the low-order word of lbColor specifies whether the bmiColors members of the BITMAPINFO structure contain explicit red, green, blue (RGB) values or indices into the currently realized logical palette. The lbColor member must be one of the following values:

    • DIB_PAL_COLORS   The color table consists of an array of 16-bit indices into the currently realized logical palette.

    • DIB_RGB_COLORS   The color table contains literal RGB values.

  • lbHatch
    Specifies 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. If lbStyle is BS_DIBPATTERNPT, the lbHatch member contains a pointer to a packed DIB. 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:

    • HS_BDIAGONAL   A 45-degree upward, left-to-right hatch

    • HS_CROSS   Horizontal and vertical crosshatch

    • 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. If lbStyle is BS_SOLID or BS_HOLLOW, lbHatch is ignored.

Remarks

Although lbColor controls the foreground color of a hatch brush, the CDC::SetBkMode and CDC::SetBkColor functions control the background color.
