Hi all
the map creation for PDF increases the size of TTF labels since the map
is requested with a higher resolution and is then stuffed into a lower
width/height as it actually is. This was to improve the print quality,
especially of fine structures. But it requires higher original text
sizes because they're shrinked with the map image.
If you define a lower resolution for the PDF output in the config xml
then also the labels are not or less increased:
<print>
<pdfres>2</pdfres>
Setting it to 1 should not change the label sizes any more.
Since MS 5.6 they introduced a new mechanism that could probably make
this workaround obsolete, see
http://mapserver.org/development/rfc/ms-rfc-55.html
I have not had any look at it, though.
