SVG generation from Matlab / Octave
Summary
| Some Matlab / Octave routines to create scalable vector graphics (SVG) output |
They are then imported into a vector graphics program and edited further.
Here is a compact example that generates an SVG image (scalable vector graphics).
The image can then be further edited using a vector graphics drawing program such as Inkscape.
Downloading the example
- Download the zip archive
- Unzip to c:\temp (or anz other folder)
Running the demo
- From the Matlab / Octave command line, type
addpath('c:/temp') - type
svgdemo - The demo writes its output to c:\temp\test.svg.
- Drag-and-drop c:\temp\test.svg into a web browser for viewing
- In the web browser, use the reload button after re-running the example
- Drag-and-drop into Inkscape (or another vector graphics program) for editing
Example
Demo program (included)
| fid=svgheader('c:/temp/test.svg'); indep=0:0.001:1; x=indep*600; y1=100+100*sin(indep*2*pi); y2=100+100*cos(indep*2*pi); y3=100+100*sin(2*indep*2*pi); y4=100+100*cos(2*indep*2*pi); svgline(fid, x, y1, 'stroke', 'red'); svgline(fid, x, y2, 'stroke', 'green'); svgline(fid, x, y3, 'stroke', 'blue'); svgline(fid, x, y4, 'stroke', 'black'); svgfooter(fid); |
Result
Opening test.svg will render the SVG file in your browser, if it supports the format.
Going further
It is fairly easy to generate other SVG shapes from Matlab/Octave.Here is a list of further examples.
The official SVG reference manual is here.
A list of color names can be found here. The previous link also explains hex notation, as for example #ff0000 for red.
