public static SvgDocument loadFromStream(InputStream stream, SvgLoadOptions options)
Parameters
stream
The stream containing SVG data
options
Options to use during load. If this parameter is null, then a default SvgLoadOptions object will be used.

The SvgDocument object this method creates.
Example
This example will load a SVG file from a web stream and show its properties
