SVG back to PlantUML

asked Jul 14 in Question / help by anonymous
hi all,

I am new in using PlantUML,

initially created sequence diagram and created .SVG, as the idea is that work is "compatible" with confluence.

now I want to re-use that .SVG to make some changes and create a new seq. diagram and .SVG.

SVG is in my local hard disk,

should I build the right URL to decode it back?

can someone , please help,

kind regards

luis

Check out https://plantuml.com/command-line#ce21470ab49d1d19 section on extracting metadata from an image (i think it would work for SVG as well as PNG), it might be what you need.

I expected to be able to use the "-metadata" switch on a .svg to extract the source stored in the metadata.  But this returned "null" in my tests.  I'm not sure if this is a bug - the doc only refers to it working with .png, but I can't see why it shouldn't work with .svg as well. 

But the good news is that SVG files are text, so if you load it into a text editor you should be able to find your source code and copy it into a new puml file.

Unless you deliberately old plantuml to exclude the source from the svg, the svg should contain the original source as a comment at the end of the file.

For example check the source of this file:
