Mapper

Hi!
Did you hear about OpenOrienteering Mapper
(http://oorienteering.sourceforge.net/?p=92) ?
Mapper is a tool writen on C++ with Qt GUI (like LibreCAD) for
creating orienteering maps used user symbols sets, and the result is a
vector-like map, that can be printed or exported to different formats.
It has one very interested future option: Print->Printer or
exporter->Export to PDF or PS.
As I understand, that use some native Qt to PDF export. Is it real
make analog PDF export option for LibreCAD?
Yes, I know about difference in licenses of Mapper and LibreCAD, but
Qt is licensed in many different licenses, and if PDF export is a
native Qt option it can be used in LibreCAD without license-collision.
What you think?
Regards, Eugeniy F.

- I totally agree with you, Ries.

- For my own, (in Windows) I use PDFCreator that work very well, and is
Open Source :-)

in unix-like, there's a cups-pdf program to do get PDF from printing. Not sure about a solution in windows though.

Eugeniy,

I current feel that PDF 'export' is a task of the printing sub-system and shouldn't
be part of an application. OSX as a print to PDF function, and I am sure Linux
can do the same through CUPS. For Window I believe there are several PDF
printer drivers that do the same.

Thomas Schöps, main developer of Mapper, made a patch: "DXF Templates", - that add possibility to use DFX-files as background for making map!

About using PDFCreator:

Mostly of polygonal and straight lines exported to PDF well. But if it are curves (ellipses or cycles) in drawing then results - curves are TREMBLING in PDF.

See my test-results bellow:

Rise,
I test Mapper for get PDF output by 2 ways:

1-st) using INTERNAL exporter ("Print"=>"Printer or exporter"=>"Export to PDF or PS")
Result - perfect contours and paths.

2-nd) using EXTERNAL virtual printer ("Print"=>"Printer or exporter"=>"PDFCreator")
Result - damaged most contours "ends", many "artefacts" in paths fills, and many other problems.

See test-results bellow:
http://upwap.ru/2226592

Maybe INTERNAL EXPORTER for LibreCAD not so bad idea ?!

P.S.: About using PDFCreator for LibreCAD and problems with it I wrote in previos post!

This screenshot from LibreCAD print-window or from pdf-reader?
Because in (LibreCAD 2.0a3, win7) print-window my drawing look not so bad, but in pdf-reader (SumatraPDF and Foxit) output PDF-file looked bad.

I experienced the same problem with the jittery curves. They look fine on LibreCAD but once exported (print to Adobe PDF), they look jittery. Exporting as any image format (jpg, png, bmp) has the same issue, also jittery.

I'm using version 1.0.2, win xp, 32bits.

Hi Andre,

Please test our 2.0 series, as this bug was fixed.

It might not be straight forward to backport the fix back to 1.0 series.

Re: Mapper

dxli,

I downloaded version 2.0.0 alpha4 and repeated the PDF generation process, it still persists.

I opened a file originally created using 1.0.4 on the new version and printed as PDF. Seeing that it was still jittery, I drew another curve on 2.0.0alpha4 to check if the issue was on which version the circle was drawn. The blue circle was drawn using 1.x and the green drawn on 2.0.0alpha4.

Re: Mapper

Actually, I think I can reproduce this bug here.

I will try to come up with a fix, but I'm very busy on travelling now.

Hope Rallaz or Ries can have some time to review the function:

void QC_ApplicationWindow::slotFilePrint();

line 3299 of file librecad/src/main/qc_applicationwindow.cpp
