Description

I can't print in big size (A0). Under 1.7.3 or 1.9.90 under windows XP.
Many errors or crashs. I'v first tried to export to PDF in A0 with raster (300dpi) or not, but without success (A3 work).
After that, I'v tried to print to a virtual printer (PDFCREATOR), I'v some success in A1 but failed again in A0.

History

#1 Updated by Giovanni Manghi almost 13 years ago

This is a known "issue" on Windows machines, in particular XP/32bit. Not sure if it is a QGIS issue or a OS limitation when it comes to use of large amounts of memory. I don't have many chances to make deep tests on this matter, so I would like to ask if can help. Try print the same project on a Vista/Seven/Linux 32/64bit machine and see if it goes better.

Did you made a test on a different OS 32 or 64 bit?

It's working on MacOSX. I don't have access to a Vista Windows.

This should mean/confirm that is a memory issue of Windows XP 32bit.

If you can share a project that is not printing on XP 32bit I can manage to test it on Linux and Seven.

I can confirm this for Windows XP.

About one year ago I did some A0-pdf print tests with a client. While on his XP machine the pdf either failed or was corrupted (not sure which one of those), doing the same on my ubuntu 32bits laptop succeeded at that time.

this is also what I'm observing and what I have been told by others. It seems anyway that Vista/Seven 32 bit are not suffering of such memory bad management. I believe that we should "catch" if a user is using XP 32bit and letting him know that in the composer he can find limitations.

The "Create PDF" of Version 1.7.3 also crashes on Win7 64bit, I tested it with .ecw and tiff. Version 1.6.0 has no Problem to create A0 pdf with 600dpi with XP and Win7 64bit.

the seems a qgis problem

As it is confirmed is a regression, I'll upgrade the priority of this ticket, considering also the importance of this issue in daily work of many qgis users.

I tested the egis 1.7.4 BAD allocation problem on winxp with a collegue of mine. She frequently has this bad allocation problem, I have this problem just with her projects.
As suggested by Giovanni we tried to re-create the same project with qgis 1.6 and she printed her map correctly. Then she tried to use again the 1.7.4 and she got again the bad allocation pop up.

Then we tried to recreate the project from the beginning. And we realized that: she loaded the shapefiles as "folder" and I loaded them as "files": if she loads shape files as "files" it works correctly.

But there's anyway something strange because she printed layout without problems for weeks loading shapes as folders!

Marco got the crashes also on qgis 1.6, so it seems to be indeed a memory management problem on win32 when using large formats and heavy layouts. The solution will be qgis 64 bit on win64, or (I guess) add more memory on win32 machines.

This should be closed as "won't fix", but I'll Marco to take the more appropriated action.

#16 Updated by Nathan Woodrow over 12 years ago

I don't think closing it as "won't fix" is a good move. Sure it's not a easy fix but I'm sure it can be fixed. There must be something that is causing the memory issues and should be investigated if we can. I can print A0 in MapInfo, ArcGIS, and every other GIS program. So we need to fix it at some stage.

#17 Updated by Paolo Cavallini over 12 years ago

Could this be considered fixed when a 64bit Win package is available (both standalone and osgeo4w)? Are there still 32bit Win machines around?

The 64bit installer would be independant of OSGEO4W. OSGEO4W doesn't have 64bit binaries. I suppose there are still plenty of 32bit machines (or better put: machines running the 32bit version of Windows) out there.

Then what about adding a warning when a user prints (a large format?) on win?

#21 Updated by Marco Hugentobler over 12 years ago

It should work much better on 32bit machines with change 0bf56ab225789dacbd0e7a6523486eda2b054d67 for many cases. Print as raster and to image won't work still, but e.g. to A0 pdf or directly to printer should be possible.

#22 Updated by Jürgen Fischer over 12 years ago

BTW buffered labels with old labeling can also cause the print output to explode.

#24 Updated by Giovanni Manghi over 11 years ago

This is still an issue (and causing crash) on the latest master revision (tested on a Windows 7 VM with 4gb of ram):

The attached project is made of a hand full of Spatialite vectors, no fancy symbology, no labels.

Printing as vector works up to A0 and 600dpi.

Printing as raster causes QGIS to crash printing in A0 at 300 dpi (works at 250) and printing in A1 at 450 dpi (works at 300).

Printing as raster (A0 600dpi) fails also on Linux, but instead of crashing it produces silently a blank pdf.

#25 Updated by Giovanni Manghi about 11 years ago

  • Status changed from Open to Closed
  • Resolution set to fixed

I have done some extensive test with the new QGIS 64 bit for Windows.

http://trac.osgeo.org/osgeo4w/

and I was able to print complex maps, with labels, wms layers, large postgis layers, etc., both as vector or raster at resolutions up to 600dpi on A0 layouts, with no problems whatsoever.

Please reopen if necessary.
