Adding attributes other than ID to a group tag

[huynhj02]

Hi! I am using JFreeSVG for a project and was wondering if there was any way I could add additional attributes onto a group tag?

Ex: currently I know I can add an id to the group tag, but if I wanted to add an attibute like "filepath" to my group tag (so that the tag would read something like < g id="unique-id" filepath="unique-filepath" >, is there an easy way to do so?

Thank you so much for your time!

EDIT: Oops, I didn't realize the example wasn't visible, added spaces between the < > brackets.

That's not supported at present but I suppose the rendering hint SVGHints.KEY_BEGIN_GROUP could be modified to support it. Right now it expects a String instance for the value and uses that as the group ID. It could check for an instance of Map<String, String> and consider each entry in the map to be an attribute-value pair and simply write those into the SVG output. Would that work for you?

Yeah! That solution would be great if it could be supported.

Hey! I was planning on making a PR to add this feature in, but it turns out it was already supported! The SVGHints.KEY_BEGIN_GROUP can take a value of Map<String,Object>, which is then used to create an attribute-value pair. See Line 979 of SVGGraphics2D.java for more, just wanted to leave a note in case anyone else wanted to use such a feature.

So, first of all I'm glad the feature is there already! But then, I apologise for not remembering it. In fact I was mislead by the Javadocs, so I'm about to commit an update for that.

No worries! Thank you for maintaining and updating this library, really appreciate it.
