Unoconv export to PDF - image poor quality

I'am using unoconv to convert .odt files with images to .pdf. This is done on CentOS Linux Server.

After conversion by unoconv images in PDF have poor quality - something like jpg quality 80%-90%. I would like to keep them with original 100% quality. I tried with jpg, png, gif, tif, but the effect is always the same.

This however is only unoconv problem. After converting .odt to PDF using Writer on the same server, and setting image quality to 100%, everything is ok, and the images quality is good. It seems that I unoconv has some default pdf quality setting, but how can it be set to 100%?

Yes, that's an important thing we should improve. Currently the filters are being used with the default options, but it would be nice if we could control those options to influence the filters.

In fact the TODO list has many other features that look interesting, unfortunately programming with UNO is a daunting task... You're welcome to look at the internals of unoconv (all python) and see if you find a way to influence options.

I am happy to help you and integrate those items in a generic way once we have found a way to do it. (It's the searching for information that takes the most times, not the implementation)

I have added this functionality this night to unoconv, you can find it in the subversion trunk at:

http://svn.rpmforge.net/svn/trunk/tools/unoconv/

The way to use it is by doing:

unoconv -f pdf -e Quality=100 <file>

More feedback is needed !
