needed by the segment count, not the max value allowed

Roberto Fernandez Bautista 778c64de88 Implement ClearArcs() and check curved polys don't get a booleanOp 
We cannot (yet) support passing several curved outlines through clipper.
In these cases, the caller should ClearArcs() before processing.

Roberto Fernandez Bautista a9a8aa8243 SHAPE_LINE_CHAIN splitArc on Insert, Remove and Replace 
This ensures that the arc shapes remain correct after removing
a point belonging to an arc or inserting a point in the middle
of an arc.

Simplify implementation of Replace( ..., aP ). Now a Remove
operation followed by an Insert operation.

Improve QA test for SHAPE_LINE_CHAIN Append, Insert and Replace

Implement SHAPE_LINE_CHAIN::splitArc to break up an arc into two

Implement SHAPE_ARC::ConstructFromStartEndCenter and add qa test

Roberto Fernandez Bautista 3f73d8c2b5 SHAPE_LINE_CHAIN::Area() should always be positive 
The algorithm relied on the assumption that the points were
ordered anti-clockwise. When ordered in a clockwise fashion, the
result was correct but negative.

for more information.

Roberto Fernandez Bautista c3051ba48a Refactor SHAPE_LINE_CHAIN to allow two shapes per point 
m_shapes now has two possible indices. The first one is populated if
the point is associated with an arc and the second index is populated
if the point is shared between two arcs.

Marek Roszko eff75b630f Get rid of anonymous struct typedefs 
We are using C++14 where there is no reason for this and is banned in C++20 under P1766R1. MSVC generates a warning under C++14 as a reminder.

jean-pierre charras 17737af130 Fix some issues related to SHAPE_ARC: 
- Some are related to shape errors when the allowed error to approximate circle
by segment is large and arc radius small.
- fix the actual error used in ConvertToPolyline().
- Use SHAPE_ARC::DefaultAccuracyForPCB() instead of a fixed value as extra margin
in zones. It should not change something, because it is also a fixed value
(5 micrometers), but it is not a magic number.
-TransformArcToPolygon() fix some issues and add a new algo, based on the arc actual
outline shape (initial algo is still available in code, just in case).
 2021-06-30 13:33:49 +02:00
jean-pierre charras bcb5618315 Fix incorrect calculation in TransformCircleToPolygon(), only noticeable 
when the allowed aError is (unusually) large.
 2021-06-28 18:51:37 +02:00
jean-pierre charras fa49b54f93 Fix minor issue in TransformCircleToPolygon() when aError is set to a large value. 
pcb_painter.cpp: add (but not activate) compil option to show the conversion
of SHAPE_ARC::ConvertToPolyline as segments, for debug purposes.

jean-pierre charras 310adedf85 Add GetCircleToSegmentError() to geometry/geometry_utils. 
This function returns the error created by a circle to segment approximation.

jean-pierre charras 3c81403424 Refinements in Arc to Polygon transform: slightly better shapes of arc ends. 
Note also the transform is still not good: the same parameters are applied
to convert inner arc, outer arc and middle arc of a thick arc to segments.
But these parameters depend on arc radius (or circle radius) value.
 2021-06-26 14:20:55 +02:00
jean-pierre charras 31d7a0a8d1 TransformArcToPolygon(): slightly better approximation of arc. 
The error between the "right" shape and the polygon is slightly smaller.
The approximations of the inner arc and the outer arc are better, but not perfect.
Also add (for test and debug purpose only) the code to show the polygon when
drawing a PCB_ARC (currently disabled)
