Images inside group polygons
You can use the groupContentDecorator callback
to draw arbitrary content in each group polygon. This example loads a set of
social icons in the SVG format and
renders them inside FoamTree.
What's in the code?
using the groupContentDecorator to draw
custom contents inside group polygons
asynchronous loading of SVG images, redrawing FoamTree once new images finished loading
a workaround for the Firefox
bug related to SVG rendering. Please also note that the quality of SVG rendering onto Canvas on Firefox
seems much lower than on other browsers.
