Algorithm (Workflow)
This function, svgpolylineofCPL, is designed to write closed contour lists (CPLs) as polygons or polyline elements in SVG format, typically for use with a laser cutter. The function is part of the SG-Library and was created by Tim Lueth.
Input Parameters
- fid: A file identifier where the SVG content will be written.
- CPL: A Close Contour List, which is a list of points defining the shape to be drawn.
- stroke (optional): The color of the line, defaulting to 'red'.
- width (optional): The width of the line, defaulting to 0.1.
- fill (optional): The fill color of the shape, defaulting to 'none'.
Algorithm Steps
- Initialize default values for
stroke, width, and fill if they are not provided in varargin.
- Convert the input
CPL to a format suitable for processing using CPLofPL.
- Determine the number of separate contours in
CPL using separateNaN.
- Iterate over each contour:
- Extract the current contour using
separateNaN.
- Check if the contour is closed by comparing the first and last points.
- If closed, write a
<polygon> element to the file. If not, write a <polyline> and issue a warning.
- For each point in the contour, write its coordinates to the file in the format
x,y.
- Complete the SVG element with the specified
stroke, stroke-width, and fill attributes.
