HATCH entity

Introduction.

A hatch entity is a rather complex and intricate object to write to a DXF file, nevertheless, we'll have to try.
First a header and common values for the hatch is written to file, then follows the hatch boundary data and the hatch pattern data.

  1. dxf_hatch_write ():
    write hatch header and common values.

    Now follows the hatch boundary path data and the hatch pattern data:

  2. dxf_hatch_boundary_path_write ():
    write boundary data which consists of one or more of either:

    1. dxf_hatch_boundary_path_edge_write ():
      write the edges of one or more boundary paths, edges consisting of either:

      1. dxf_hatch_boundary_path_edge_line_write ():
        write a line entity.

      2. dxf_hatch_boundary_path_edge_arc_write ():
        write an arc entity.

      3. dxf_hatch_boundary_path_edge_ellipse_write ():
        write an ellipse entity.

      4. dxf_hatch_boundary_path_edge_spline_write ():
        write a spline entity.

      The edge entities making a boundary path should form a closed loop, for else the hatch pattern will "escape" from this area through the "gaps" in the boundary path.

      In case a very dense hatch pattern is chosen, it may take very long for AutoCAD (or any other CAD application using the DXF file) to load the hatch entity, for it will try to apply the hatch pattern to it's entire universe ;-(

      It is for this reason that applying a very dense hatch pattern is considered a Bad Thing (TM); better use the SOLID hatch pattern to obtain a similar result.

    2. dxf_hatch_boundary_path_polyline_write ():
      write a polyline entity and vertices.

      1. dxf_hatch_boundary_polyline_vertex_write ():
        write a series of vertices (minimum should be 3).

      The polyline making a boundary path should form a closed loop, for else the hatch pattern will "escape" from this area through the "gaps" in the boundary path.

      In case a very dense hatch pattern is chosen, it may take very long for AutoCAD (or any other CAD application using the DXF file) to load the hatch entity, for it will try to apply the hatch pattern to it's entire universe ;-(

      It is for this reason that applying a very dense hatch pattern is considered a Bad Thing (TM); better use the SOLID hatch pattern to obtain a similar result.

  3. dxf_hatch_hatch_pattern_data_write ():
    write hatch pattern data consisting of definition line(s) and seed point(s).

    1. dxf_hatch_pattern_def_line_write ();
      write one or more pattern definition lines which are either continuous or dashed.
    2. dxf_hatch_pattern_seed_point_write ();
      write one or more seed points.

int dxf_hatch_boundary_path_polyline_point_inside_polyline ( DxfHatchBoundaryPathPolyline *  polyline,

Compute if the coordinates of a point p lie inside or outside a DXF hatch boundary path polyline polyline entity.

Author:
Paul Bourke <http://www.paulbourke.net/geometry/insidepoly/>
Adapted for libDXF by Bert Timmerman <bert.timmerman@xs4all.nl>

A solution by Philippe Reverdy is to compute the sum of the angles made between the test point and each pair of points making up the polygon.
If this sum is ( $ 2\pi $) then the point is an interior point, if 0 then the point is an exterior point.
This also works for polygons with holes given the polygon is defined with a path made up of coincident edges into and out of the hole as is common practice in many CAD packages.

Note:
For most of the "point-in-polygon" algorithms there is a pathological case if the point being queries lies exactly on a vertex.
The easiest way to cope with this is to test that as a separate process and make your own decision as to whether you want to consider them inside or outside.
It is assumed that the polygon is simple (does not intersect itself).
Returns:
INSIDE if an interior point, OUTSIDE if an exterior point, or EXIT_FAILURE if an error occurred.

Todo:
This is a dead code path.

Parameters:
polylineDXF hatch boundary path polyline entity.
pointThe point to be tested for.
