Elevation profile PDF export #57880

Closed zsiki closed 4 months ago

zsiki commented 4 months ago

What is the bug or the crash?

Exporting any elevation profile to PDF there is a scaling problem in the created PDF. Only a very small part of the upper left corner of the profile is visible in the exported PDF. Export the profile as image is correct using the same chart ranges as in PDF export. I suppose it is a scaling problem.

Steps to reproduce the issue

  1. Open an elevation raster/DEM
  2. Open the elevation profile panel
  3. Capture a line on the DEM
  4. Click on Export PDF tool
  5. Accept default chart ranges ans save
  6. Open the exported PDF to see the issue.

Hello, I’m totally new to GitHub and encountered the same problem in QGIS when importing an elevation profile from a PDF. Could you please teach me how to implement the solution provided in this post in my QGIS?

agiudiceandrea commented 3 months ago

@Kasmhyr, this issue report is about exporting an elevation profile to PDF using the Elevation Profile panel. Please create a new issue report providing all the requested detailed info.

Kasmhyr commented 3 months ago

@agiudiceandrea Ohh, sorry. Thank you for the information.

@nyalldawson your correction does not work for me in QGIS version 3.34.9 and 3.34.10 image

zsiki commented 3 months ago

A better picture: image

agiudiceandrea commented 3 months ago

@zsiki unfortunately the fix is currently only available in the latest QGIS 3.38. @nyalldawson the automatic backport to 3.34 failed. Manual backport at https://github.com/qgis/QGIS/pull/58433.

zsiki commented 3 months ago

Thanks, a reason to upgrade...

agiudiceandrea commented 3 months ago

@zsiki, the fix will be available also since QGIS LTR 3.34.11.
