Sorry. I don't see your point . Label placement works like always... (?)

> What is the typical size (pixels/lines) of the PNG?
Important point. 
* Papersize A4(210mm x 297mm ) and A3(297mm x 420mm)
* Maps cover about 80% of the Paper
* 150DPI

-> Approx 1,700,000 pixels for A4 and 3,400,000 pixels for A3.

We'd like to generate bigger Maps: More dpi, bigger papersizes.
Problem is not Mapserver but the PDF-Generator. (Runs out of memory).

In the case, that the generated pics become to large for mapserver,
one could use tiles. But this would not solve the memory-problem of the
PDF-generator.

This is done by the Apache-FOP.

1:50,000)?
The program controls the extent of the Map (in Meters).
The program controls the size of the image in the PDF (in mm).
-> Control over the scale.
