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.

||
|
|
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. |
