a030eff963 cameo/: new command "flip" to flip paths on the X or Y axis 2012-08-23 09:04:44 -03:00

c73509dacc cameo/fped2d2z.pl: new option -t Zmax to set the height of the workpiece 
This is similar to -r, except that we don't swap X and Y, and we use
the specified value instead of searching for the maximum in the input
data.

53fe70950d poly2d/: try to work around spurious aborts in CGAL::create_interior_skeleton_and_offset_polygons_with_holes_2 
cameo encountered spurious aborts with the following message:

  terminate called after throwing an instance of 'CGAL::Precondition_exception
  what():  CGAL ERROR: precondition violation!
  Expr: is_simple_2(first, last, traits)
  File: /usr/include/CGAL/Polygon_2/Polygon_2_algorithms_impl.h
  Line: 420

These aborts come and go even if just the coordinate origin is slightly
changed. Setting CGAL_POLYGON_NO_PRECONDITIONS in p2d_area_holes.cpp
made them go away in some cases, but cameo could still run into an
assertion violation (in CGAL).

We now check all the polygons, outer boundary and holes, being sent to
CGAL::create_interior_skeleton_and_offset_polygons_with_holes_2 for
simplicity, and stop recursing if there is any hint of a problem.

This seems to avoid trouble for now, but the issue deserves further
investigation.

072b7804ee cameo/: experimental command "outside" to detect real outer borders 
Should be merged into tool_comp_paths later.

382d14dcbb cameo/path.c: move assert(path_is_closed) into function and improve diagnostic 
It's often hard to find an offending path. To help with this, we
now print the start and end coordinates.

038667d0d8 poly2d/p2d_hsort.c (p2d_hier_free): use p2d_free, not p2d_free_all 
This caused a double free.

46c8f8653c poly2d/: automatically switch between clockwise and counter-clockwise polygons 
The only functions that care about this at the moment are from CGAL,
and there we can determine from context what to do.

8ce420b10b cameo/excellon.c: recognize G90 code (absolute mode) 
Recent KiCad emits this. We're in absolute mode anyway, so we simply
ignore it.

c422be5543 spool: support jobs with more than one file

6d70656ab2 cameo/path.c (path_offset): handle also degenerate polygons of only one point 
To do: use a square, not a circle. Also, extend this to degenerate
polygons consisting of two points.

calculating their start and end points.

489ca9c24d cameo: documented "area"; miscellaneous cleanup 
Also removed the tool diameter argument. We use the diameter from the
path, like "offset" does. In the long run, this convention probably
doesn't make sense, though.

for an entry.

(yet almost always harmless) things at the end of a job.
