Member Function Documentation

◆ collect_hole()

void GBR_TO_PCB_EXPORTER::collect_hole ( const GERBER_DRAW_ITEM aGbrItem)
private

Collect holes from a drill layer.

We'll use these later when writing pads & vias. Many holes will be pads, but we have no way to create those without footprints, and creating a footprint per pad is not really viable. We use vias to mimic holes, with the loss of any hole shape (as we only have round holes in vias at present). We start out with a via size minimally larger than the hole. We'll leave it this way if the pad gets drawn as a copper polygon, or increase it to the proper size if it has a circular, concentric copper flashing.

◆ export_copper_item()

void GBR_TO_PCB_EXPORTER::export_copper_item ( const GERBER_DRAW_ITEM aGbrItem,
int  aLayer 
)
private

◆ export_flashed_copper_item()

void GBR_TO_PCB_EXPORTER::export_flashed_copper_item ( const GERBER_DRAW_ITEM aGbrItem,
int  aLayer 
)
private

Write a synthetic pad to the board file.

We can't create real pads because the Gerbers don't store grouping/footprint info. So we synthesize a pad with a via for the hole (if present) and a copper polygon for the pad.

Parameters
aGbrItemis the flashed Gerber item to export.

◆ export_segarc_copper_item()

void GBR_TO_PCB_EXPORTER::export_segarc_copper_item ( const GERBER_DRAW_ITEM aGbrItem,
int  aLayer 
)
private

Write a set of tracks (arcs are approximated by track segments) to the board file.

Parameters
aGbrItemis the Gerber item (arc only) to export.
aLayeris the copper layer to use

◆ export_segline_copper_item()

void GBR_TO_PCB_EXPORTER::export_segline_copper_item ( const GERBER_DRAW_ITEM aGbrItem,
int  aLayer 
)
private

Write a track (not via) to the board file.

Parameters
aGbrItemis the Gerber item (line only) to export.
aLayeris the copper layer to use.

◆ export_via()

void GBR_TO_PCB_EXPORTER::export_via ( const EXPORT_VIA aVia)
private

Write a via to the board file.

Some of these will represent actual vias while others are used to represent holes in pads. (We can't generate actual pads because the Gerbers don't contain info on how to group them into footprints.)

◆ MapToPcbUnits()

double GBR_TO_PCB_EXPORTER::MapToPcbUnits ( int  aValue) const

Map GerbView internal units to millimeters for Pcbnew board files.

Parameters
aValueis a coordinate value to convert in mm.
