George Kirkham commented on OPENMEETINGS-247:
---------------------------------------------
Hi, After further testing it is the zoom value which is worthwhile, however
this makes files larger and so there may be a point to having both the zoom and
jpegquality settings adjustable.
To make such a change, I have identified the following possible code areas
which would need changing, however as I am not familiar with OpenMeetings code,
so there is a high possibility that there is more changes required (like
ensuring that values are within appropriate ranges. My hope is the below
information may assist with a change to the code.

> Key: OPENMEETINGS-247
> URL: https://issues.apache.org/jira/browse/OPENMEETINGS-247
> Project: Openmeetings
> Issue Type: Improvement
> Components: Converters
> Affects Versions: 2.0 Apache Incubator Release
> Environment: Debian Squeeze,
> openmeetings-2.0.0.r1328537-20-04-2012_2319.tar.gz (Build #43)
> Reporter: George Kirkham
> Labels: configuration, conversion, converter, quality
> Fix For: 2.0 Apache Incubator Release
>
>
> I have the need to improve the quality of converted PDF, Word or PowerPoint
> files, that is increase the resolution of the conversion process for Word
> PDF and PowerPoint files are converted to *.swf files.
> Currently the quality of any images within converted documents is so poor
> that we cannot clearly read the text within the images contained in documents.
> This may be able to be resolved by allowing the quality of file conversion to
> be adjustable in the administration section of OpenMeeting or in the
> config.xml file.
>
> Checking the OpenMeetings log it would seem that it is using pdf2swf without
> any "-j" setting, I found this in the log file;
> args: [/usr/local/bin/pdf2swf, -s, insertstop, -s, poly2bitmap, -I,
> /user/lib/red5/webapps/openmeetings/upload/files/le8...
> Checking some of the source code I noticed that in the code these does not
> appear that the "-j" option is being used, therefore I guess the default
> value of 85% is being used when converting documents.
>
> -j , --jpegquality quality Set quality of embedded jpeg pictures to
> quality. 0 is worst (small), 100 is best (big). (default:85)
>
> I could not find any settings in the
> /usr/lib/red5/webapps/openmeetings/config.xml file for the pdf2swf arguments.
>
> And I don't think that I can change this in OpenMeetings, it is most likely
> set somewhere in the source code?
>
> Sadly I have never managed to successfully build OpenMeetings using "ant",
> but checking the source code, maybe the place to add the "-j" option may be
> in;
> ./openmeetings/trunk/singlewebapp/src/org/openmeetings/app/documents/GenerateSWF.java
> line 216
> // Create the Content of the Converter Script (.bat or .sh file)
>
> I wonder if the developers would be able to add the "-j" option as a user
> setting, and allow this value to be adjustable by administrators?
