Hello,

since this is a question directly related to the linux-gazette I'm CC'ing the mailinglist there (TAG).

be aware that recent versions of ::OODoc broke the script. A tiny correction will make it work again, see: http://linuxgazette.net/132/lg_talkback.html#talkback.02 http://www.khherrmann.de/Programs.shtml http://www.khherrmann.de/Code/img2ooImpress.pl

the inbuilt mini-help says:

  img2ooImpress.pl
  Usage:
  img2ooImpress.pl ImageFileList [outputfile.odp]
  ImageFileList is a file containing all images to import

and yes, the script expects a filename containing all images, each on its own line. You can easily create a file like that by following the examples in the original linux-gazette article.

essentially, after making sure your files are sorted properly by ls something like:

ls image*.jpg > filelist

will write all jpg-images starting with "image" into the file "filelist".

running img2ooImpress.pl filelist

will then create the output odp file (default odp name, if you pass a second parameter it will be used as output file).

no -- it simply fetches the first commandline argument into $imgFileList -- and subsequently opens that file (or fails).

No -- you can keep the perl script in ~/bin (and add ~/bin to your PATH). Also the given file-name for the file-list can contain a full path -- so no need to have it lokal in the the same directory as the perl script OR the images.

ls imgp000*jpg > filelist

filelist then contains

imgp0001.jpg
imgp0002.jpg
imgp0003.jpg
imgp0004.jpg
imgp0005.jpg

If the script produces some output (instead of complaining) see the new version for current OODoc module version. With the old script this will simply produce a seamingly empty odp file.

Kind regards,

K.-H.
