svgplot
SVG creation library forked from xytis's Rasem fork.
Usage
Create an SVG object by initializing it with a size:
plot = SVGPlot.new(width: 100, height: 100)
SVGPlot is based directly on the SVG spec. Add children by calling their methods on the plot:
# Add the text 'foo' at position (1, 2)
plot.text(1, 2) { 'foo' }
# Add a rectangle
plot.rectangle(1, 1, 10, 10)
A good example of the SVG library in practice is GithubChart
Transformations
To do an SVG transform on an object, just call the desired transform method on it:
plot = SVGPlot.new(width: 100, height: 100)
plot.text(1, 1) { 'foobar' }.translate(5, 5)
You can call transforms after the fact as well:
plot = SVGPlot.new(width: 100, height: 100)
text = plot.text(1, 1) { 'foobar' }
text.scale(2)
The list of available transforms:
- translate(x, y = 0)
- scale(x, y = 1)
- rotate(angle, x = nil, y = nil)
- skew_x(angle)
- skew_y(angle)
- matrix(a, b, c, d, e, f)
