/* Functions to convert some board items to polygons
|
|
* (pads, tracks ..)
|
|
* This is used to calculate filled areas in copper zones.
|
|
* Filled areas are areas remainder of the full zone area after removed all polygons
|
|
* calculated from these items shapes and the clearance area
|
|
*
|
|
* Important note:
|
|
* Because filled areas must have a minimum thickness to match with Design rule, they are draw in 2 step:
|
|
* 1 - filled polygons are drawn
|
|
* 2 - polygon outlines are drawn with a "minimum thickness width" ( or with a minimum thickness pen )
|
|
* So outlines of filled polygons are calculated with the constraint they match with clearance,
|
|
* taking in account outlines have thickness
|
|
* This ensures:
|
|
* - areas meet the minimum thickness requirement.
|
|
* - shapes are smoothed.

|

* 3 - Creates a correction using BOOL_CORRECTION operation to shrink the resulting area
|
|
* with m_ZoneMinThickness/2 value.
|
|
* The result is areas with a margin of m_ZoneMinThickness/2
|
|
* When drawing outline with segments having a thickness of m_ZoneMinThickness, the outlines will
|
|
* match exactly the initial outlines
|
|
* 4 - recreates the same Bool_Engine, with no correction
|
|
* 5 - Add the main modified outline (zone outline) in group A
|
|
* 6 - Add all non filled areas (pads, tracks) in group B with a clearance of m_Clearance + m_ZoneMinThickness/2
|
|
* 7 - calculates the polygon A - B
|
|
* 8 - put resulting list of polygons (filled areas) in m_FilledPolysList
|
|
* This zone contains pads with the same net.
|
|
* 9 - Remove insulated copper islands
|
|
* 10 - If Thermal shapes are wanted, remove copper around pads in zone, in order to create thes thermal shapes
|
|
* a - Creates a bool engine and add the last copper areas in group A
