Error when exporting PDFs

[hansenp]

When I try to export a PDF from the isoform visualization screen (on M2 Macintosh), I get the following error:

I installed rsvg-convert (librsvg), but that didn't solve the problem. I then completely reinstalled isopret, i.e. cloned the repository again and recreated the dmg file with rsvg-convert available in the path. But this didn't solve the problem either.

The program does this

Runtime rt = Runtime.getRuntime();
        String[] commands = {"rsvg-convert", "-f" , "pdf", "-o",
                pdfFile.getAbsolutePath(), temp.getAbsolutePath() };
        Process proc = null;
        try {
            proc = rt.exec(commands);

that is, it should work if rsvg-convert is on the system path. (temp is a temporary fiule with the SVG information). Did you still get the same error after installing rsvg-convert? Does rsvg-convert work manually?

I just tried this again. On Mac (M1), I installed the following

brew install librsvg

This put rsvg-converton the system PATH and the isopretGO GUI worked. I am guessing that the dmg file for some reason did not put the app in the PATH. Could you please try this again and see if it works on your side? @hansenp

So yes rsvg-convert is in my $PATH. But I still get the error.

Do you get an error message or does it just fail?

I get the following error:

Wit the latest version of isopretGUI, which I built with mvn package, the error no longer occurs.
