Description

Resource that loads a set of lines from an svg file Every line is converted in a polyline. The line vertex reolution can be changed using a difference tolerance value. A lower tolerance results in less vertices. The uv's of the lines are normalized based on the total bounding box of the file, ie: all the lines in the file. The normals are perpendicular to the tangent of the line, the line itself is loaded in the x, y plane. When normalization is turned on the loaded lines will be placed relative to 0, with a default bounding box in the x, y plane of -0.5 to 0.5. Changing the scale will change these bounds.

Member Function Documentation

◆ init()

virtual bool init ( utility::ErrorState & errorState )

overridevirtual

Loads the svg file and extract all the lines

Reimplemented from PolyLine.

◆ isClosed() [1/2]

virtual bool isClosed ( ) const

overridevirtual

Returns: if the first line is open or closed.

Implements PolyLine.

◆ isClosed() [2/2]

virtual bool isClosed ( int shapeIndex ) const

virtual

Returns if a given line is open or closed, useful when the file contains multiple lines, where each line is converted into a shape.

Returns: if a given line is open or closed.
