The HATCHBRUSH structure contains information for creating patterns that can be repeated to fill a closed area. This is called the hatch unit and it can be one of several predefined primary types, or it can be user defined. The primary types are: Rectangle, Circle, Triangle and Line.

Members

HATCHBRUSHSTYLE HatchBrushStyle

Value that indicates the hatch brush style. Possible values are:

Value Meaning
HATCH_RECTANGLE Rectangular hatches
HATCH_CIRCLE Circular hatches
HATCH_TRIANGLE Triangular hatched
HATCH_LINE Linear hatches
HATCH_CUSTOM User-defined hatches

LOGPEN LogPen

Windows LOGPEN structure that defines the pen properties used to draw the outlines of the filling units. For more information about this data type, please refer to Microsoft documentation of the structure LOGPEN.

LOGBRUSH LogBrush

Windows LOGBRUSH structure that defines the brush properties. used to fill the hatch units. For more information about this data type, please refer to Microsoft documentation of the structure LOGBRUSH.

NOTE: the data in this structure is invalid in the case of linear hatches.

L_INT nStepSize

The hatch unit size (in device units)

L_DOUBLE dLineRotAngle

Rotation angle of the hatch lines, in degrees.

This field is valid only in the case of linear hatches.

L_UINT32 dwFlags

Flags used to control the hatch filling. Possible values are:

Value Meaning
HATCH_BRUSH_CUSTOM_CLOSED Close the user defined hatch. When this flag is set, the LogBrush attributes will be used to fill the user defined area.
HATCH_BRUSH_CUSTOM_OPEN The user defined path is not closed. No filling will be applied to the hatch units and the LogBrush member will be ignored.

L_INT nPointCount

Number of points that specify the user defined path to be used as the hatch unit.

L_POINT *pEntryPoints

The user defined path points which specify the hatch units. This member should contain nPointCount elements.
