[Qgis-user] Large Format Printing (A0)

[Andreas Neumann]

Hi Tim,

We use printers from the HP DesignJet series. Works fine.

QGIS has limitations when printing large rasters. Also, WMS services may 
run into limitations, when not properly configured because QGIS would 
request huge raster chunks, larger than what WMS servers usually can 
deliver.

Also, the most recent releases fixed printing issues when dealing with 
large polygons (>5000-10000 vertices and more) - not uncommon with GIS 
datasets. There was an issue with inefficient clipping algorithms in the 
qt-engine. Marco/Jürgen patched the qt-library that caused the problems.

Marco has an open task on improving the printing engine to better 
handle/tile large rasters and WMS. I don't know if he is already working 
on this or not. Maybe Marco can comment?
