How to specify a file name for a label icon in a GraphML file?

Question

Hello,

I use a XSL file to generate a GraphML file and I would like to put my own pictures like icon label.

The path to the files are already stored in the original XML File.

If it's possible, how to do?

Answer 1

yEd does not use file paths but expects Base64 encoded image data in PNG format.

I suggest creating a sample diagram with a single image node or image icon label, saving the diagram, and inspecting the resulting GraphML file to understand what needs to be done.

As far as I know, it is not possible to generate the required image data from a file path using XSL(T) alone.

Thank you very much.

I was affraid it was not possible, indeed.
The best I can do for now is to store the path in a <data>. It could be useful in case of the use of another viewer.

Well, if you need the icons in labels and put your file paths/URLs in <data> elements that are imported as custom properties, then you could use yEd's properties mapper to batch-import the referenced images as label icons.

It appears that label icons property cannot be mapped. Am I missing something?

Probably. Hard to tell given the information at hand. What verson of yEd are you using? What did you do exactly? How did you specify the file paths/URLs for the label icons? What does you properties mapper configuration look like? Please consider uploading a sample GraphML with your custom properties and your properties mapper configuration here. Otherwise it is very difficult to understand your problem.

I was using 3.15 version, and now with 3.16 it's better ;)

Thank you very much for your time.
