plotter.h contains now only a header common to all plotters.
The code does not actually change, but it allows modifying a specific plotter
without recompiling most of kicad files.
Due to rounding issues, sometimes (especially for rotated pads) the region
(4 segments+4 arcs) was incorrectly closed (1 unit (nanometer) mismatch between
start point and end point.
Although it does not create bad shape, its breaks the round rect pad identification
in CAM tools.
start point and end point are now the same.
These pads were plotted as a segment. This is not the right way.
Pads must be flashed or plotted as regions, not painted.
They are now plotted as Gerber regions round rectangle pads.
These regions are similar to flashed pads.
Previously, the region was a usual polygon with arc approximated by segment.
Using a region with arcs is a better way because it allows CAM tools to
identify this region as a round-rect pad.
A side effect is a better shape and smaller files, however not really noticeable in fact.
Previously, for historical reasons, they were added only if
Include Netlist Attributes option was on.
But Aperture Attributes have nothing to do with Netlist Attributes, and good
Gerber files must include them.
* Split up the thirdparty code into the thirdparty folder (#3637)
* Create a new kimath static library containing all the math functions
This is part of cleaning the build system for #1906.
They are now in a specific block and no longer combined with an other command.
(combining these commands with an other command (D01 or D02) is deprecated)
Fixes#3677 | https://gitlab.com/kicad/code/kicad/issues/3677
This is the first step to allowing non-segments in the line chain.
External routines cannot be allowed to change the line chain without
going through the internal routines. To accomplish this, we remove the
Vertex() and Point() access routines and only leave the const versions.
Transformations are given for both points as well as the chain itself.
Standard apertures are circle, rect, oblong and polygon (regular polygonal shapes with 3 to 12 vertices)
The support of the standard aperture type polygon was missing in Gerber plotter.
This corrects an issue with fill segments-per-circle and moves the error
to segmetns calculation down in a number of functions to expose the
single value for approximation
Allows 0 to 4 chamfered corners, not only one.
A custom shape allow this kind of shape. However because it is a primitive,
it is easier to edit and it support thermal reliefs.
