I recently needed to recover the svg for a board outline with only the fzz file. Because the source svg is in the fzz file. Since I had to do this I figured I document how to do it for other people.
un zip the .fzz file to get the .fz file which is standard xml so edit the fz file with a text editor.
search for the text ’ instance moduleIdRef=“BoardLogoImageModuleID” ’
select the data after ’ <property name=“shape” value=" ’ til ’ </svg> ’ and copy that text in to a new svg file.
You now have an svg file but is quoted, so you need to unquote it to create a svg file that a svg editor will accept it. So edit the file and do the following substitutions (these are for vi or vim)
edit: Coming back to do this again I just noticed that the helpful forum software removed the actual xml commands below and substituted the replacement values (which is why the substitutions were identical.) I will try prefomatted mode to try and correct this …
5) :1,$s/"/"/g which substitutes all lines (there is currently only one line but later there will be lines) that is the 1.$ part. The s/ substitutes " to " the / ends the substitution, and the g causes substitution for all instances on the line. This should let you modify the command for your editor. 6) :1,$s/>/>/g to do the greater thans (>) 7) :1,$s/</</g to do the less thans. Then (otherwise the ones above screw up!) 8) :1,$s/
/\r/g to replace the quoted newlines with a new line
which unusually for me, seems to have worked correctly Hopefully the correct vi commands will make it easier to adjust the search patterns for your editor of choice, unlike substitute " for " as was there originally. Sorry about that!
Now if you save the result you can feed it to an svg editor.
