Function Documentation

ConvertGerberToPolySet()

SHAPE_POLY_SET ConvertGerberToPolySet	(	GERBER_FILE_IMAGE *	aImage,
		int	aTolerance = 0 )

Convert a GERBER_FILE_IMAGE to a merged SHAPE_POLY_SET.

All draw items in the Gerber image are converted to polygons and merged using boolean union. This handles step-and-repeat expansion.

Note: This function may populate cached polygon data in the draw items.

Parameters

aImage	The Gerber file image to convert
aTolerance	Optional inflation tolerance in nm for comparison purposes

Returns

A merged SHAPE_POLY_SET containing all copper areas
