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.

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.

- 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.

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!

Hey,

these are interesting findings, although I couldn't open the test results URL…

I do wonder what causes this and before anybody climbs on there kjeyboards to write a exporter,

we should research this a bit more.

I did had a brief talk with Dongxu about it and there might be some solutions we can look into

without writing complete exporters because somebody has to write and maintain that somehow.

Can we try this? Send me the DXF, I export ito a PDF and you import that.

Then take a look at the differences.

I could download the files now, my Russion isn't what is was…

Apparently in LibreCAD 2.0.x there has been something changed

when it comes to printing.

In LibreCAD 1.0.1 this works fine. I do admit printing is not the best

think in LibreCAD, but the PDF looked correct.

The below image is a screenshot when I used export to PDF in OSX.

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.

R. van Twisk

Re: Mapper

The screenshot was from my PDF viewer and generated (using export PDF) from 1.0.1.

it seems like that for 2.0.x there was something changed because with the 2.0.x branch (master)

the print was incorrect.

Re: Mapper

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
