          Description

          Situation: We've recently had several requests to export images in IGB as SVGs. While IGB does have the ability to export images as SVG, the libraries used are quite old and there are some weird artifacts that show up in the SVG images (see IGBF-2649).

          Task: Update the libraries used for SVG image export in IGB. This may require stripping out the current SVG library usage and using a newer one (something like this: https://github.com/jfree/jfreesvg).

                Replaced the freehep library to jfree.

                Attached is a screenshot of an SVG output using the newly integrated library.

                Tested Pranav's branch on Mac.

                Exported main view, main view with labels, whole frame, and sliced view images from Pranav's branch and IGB 10.1.0. I compared the images using inkscape. On Pranav's branch the images look much better as there are no longer overlapping parts.

                For example, here is the old version of IGB:

                Here is the new version:

                I would like to see a couple of changes in the commit before it is ready for a PR:

                • Set your IDE to not fix whitespace issues in files you are editing.
                  • I recommend creating a new branch off of main (name it IGBF-4081) and reimplement your changes as this will be easier than trying to fix the whitespaces.
                • Use the jfreesvg artifact for Java 11 and higher: <artifactId>org.jfree.svg</artifactId>
                • You should not need to add javax.xml.bind. We are using jakarta.xml.bind. See stackoverflow for more info.
                • Replace all imports of freehep with jfreesvg. If everything is working, commit, then see if you can identify if any of the imports of jfreesvg can be removed.
                • Remove unneeded freehep lines of code instead of commenting them out.

                Note from Paige on tickets we may be able to close after testing with the new SVG library:

                IGBF-1106 - Make sure saved SVG files can be opened in popular image editing tools (e.g., Adobe Illustrator) on Mac
                IGBF-2649 - This can be completed once Pranav’s ticket is closed.

                Tested on Mac and Windows using the main branch installer. SVG files look good on both systems.

                Closing ticket.

                Note that there are some visual differences between the old SVG library and the new SVG library. For example, the "barb wire" in IGB does not always appear correctly with the new SVG library, though I do not see this as an issue.
