Description TR Bentley 2011-05-22 13:21:26 EDT
Description of problem:
OpenLP has code to import and manage presentations from OpenOffice.  This has worked fine and used the python API and the document storetoURL method.
In moving for LibreOffice this code is now failing event though the documentation says that it should be able to export to a png file. 

Version-Release number of selected component (if applicable):
Latest version of F15 with all updates (not testing) applied.

How reproducible:
Every time.

Steps to Reproduce:
1.Install OpenLP and LibreOffice-impress , LibrOffice-uno and python-openoffice. 
2.start OpenLP and import a presentation 
3. import fails.
In debugging the code it fails.

        props = []
        props.append(self.create_property(u'FilterName', u'impress_png_Export'))
        props = tuple(props)
        doc = self.document
        pages = doc.getDrawPages()
        if not os.path.isdir(self.get_temp_folder()):
        for idx in range(pages.getCount()):
            page = pages.getByIndex(idx)
            urlpath = u'%s/%s.png' % (thumbdirurl, unicode(idx + 1))
            path = os.path.join(self.get_temp_folder(),
                unicode(idx + 1) + u'.png')
            from com.sun.star.task import ErrorCodeIOException
                print "A"
                print urlpath, props
                doc.storeToURL(urlpath, props)
                print "B"
                self.convert_thumbnail(path, idx + 1)
                print "C"
            except ErrorCodeIOException, exception:
                print "ERROR! ErrorCodeIOException %d" % exception.ErrCode
                import sys
                print sys.exc_info()
                log.exception(u'%s - Unable to store openoffice preview' % path)

Actual results:
An ErrorCodeIOException 2074 is thrown.  If you comment out the properties line you get an import BUT with empty images.
The problem is  props.append(self.create_property(u'FilterName', u'impress_jpg_Export'))
But it worked OK with OpenOffice.

Expected results:
a directory of png files

I guess you do not have libreoffice-graphicfilter
Comment 2 TR Bentley 2011-05-23 11:58:56 EDT
This is correct and when I added it the code started to work.
Many thanks for the prompt response.
