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.

Member	Description
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	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	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.
nStepSize	The hatch unit size (in device units)
dLineRotAngle	Rotation angle of the hatch lines, in degrees. This field is valid only in the case of linear hatches.
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.
nPointCount	Number of points that specify the user defined path to be used as the hatch unit.
pEntryPoints	The user defined path points which specify the hatch units. This member should contain nPointCount elements.
