# HatchFilling

is a two-dimensional graphics directive that specifies that faces of polygons and other filled graphics objects are to be drawn using closely spaced parallel lines.

HatchFilling["name"]

uses the specified line hatching "name".

HatchFilling[θ]

draws parallel lines with an angle θ.

HatchFilling[θ,r]

draws parallel lines with absolute thickness r.

HatchFilling[θ,r,d]

draws parallel lines with gaps of absolute thickness d.

# Details

• HatchFilling is also known as hatch or striped pattern.
• HatchFilling is typically used to fill twodimensional polygons and areas with stripes.
• Possible line hatching includes:
•  "Diagonal" diagonal lines "Horizontal" horizontal lines "Vertical" vertical lines
• HatchFilling[θ,r,d] specifies that faces of filled graphics objects are to be drawn using parallel lines with an angle θ from the horizontal, a thickness r and distance d.
• is effectively equivalent to HatchFilling[Pi/4].
