importSVG Namespace Reference

Detailed Description

SVG file importer & exporter.

This module provides support for importing and exporting SVG files. It enables importing/exporting objects directly to/from the 3D document, but doesn't handle the SVG output from the Drawng and TechDraw modules.

Functions
def	transformCopyShape (shape, m)
def	getsize (length, mode='discard', base=1)
def	makewire (path, checkclosed=False, donttry=False)
def	arccenter2end (center, rx, ry, angle1, angledelta, xrotation=0.0)
def	arcend2center (lastvec, currentvec, rx, ry, xrotation=0.0, correction=False)

Function Documentation

arccenter2end()

def importSVG.arccenter2end	(		center,
			rx,
			ry,
			angle1,
			angledelta,
			xrotation = 0.0
	)

calculate start and end vector and flags of an arc given in center parametrization
see http://www.w3.org/TR/SVG/implnote.html#ArcImplementationNotes
returns (v1,v2,largerc,sweep)

arcend2center()

def importSVG.arcend2center	(		lastvec,
			currentvec,
			rx,
			ry,
			xrotation = 0.0,
			correction = False
	)

calculate (positive and negative) possible centers for an arc in endpoint parameterization
see http://www.w3.org/TR/SVG/implnote.html#ArcImplementationNotes
rotation or x-axis has to be specified in radians (CCW)
the sweepflag is interpreted as: sweepflag <==>  arc is travelled clockwise 
returns [(vcenter+,angle1+,angledelta+),(...-)]

getsize()

def importSVG.getsize	(		length,
			mode = 'discard',
			base = 1
	)

parses length values containing number and unit
with mode 'discard': extracts a number from the given string (removes unit suffixes)
with mode 'tuple': return number and unit as a tuple
with mode 'css': convert the unit to px assuming 90dpi
with mode 'mm': convert the unit to millimeter assuming 90dpi

makewire()

def importSVG.makewire	(		path,
			checkclosed = False,
			donttry = False
	)

try to make a wire out of the list of edges. If the 'Wire' functions fails or the wire is not
closed if required the 'connectEdgesToWires' function is used

transformCopyShape()

def importSVG.transformCopyShape	(		shape,
			m
	)

apply transformation matrix m on given shape
since OCCT 6.8.0 transformShape can be used to apply certain non-orthogonal
transformations on shapes. This way a conversion to BSplines in
transformGeometry can be avoided.
