--- Comment #7 from Marc Véron <veron at veron.ch> ---
The way how the images are first downsampled and then added to the PDF file is
simply wrong. It leads to a very poor quality of the printed cards. The images
should be added to the PDF with a higher quality and downscaled (transformed)
with PDF internal operators. Rule of thumb for this kind of printing is to have
it 5 times bigger (I know such things; I do PDF stuff since 1995). This is
fixed in my patch, and the wole card creation works the same way as before.

I do not think that it makes much sense to expose this var to the end user,
because it is merely a technical thing.

For the encanced quality, see:
