Description

The scaling of Annotations seems to behave wrong when printing

This is how it looks like in the layout view:

However if I print the map as PDF it looks like this (scaling seems off):

A possible workaround is to change the rendering settings of the map from the Item Properties section. Changing the rendering settings of the map in the Item Properties section to Darken did the trick for a simple example. However, for a more complex map, it didn't work...

Fix incorrect annotation scaling when exporting layouts

Previously, annotation size and position always used pixel units. This
did not work well when exporting layouts, resulting in tiny annotations
(it also caused issues when moving projects between hidpi/non hidpi
displays).

Instead, use millimeters for annotation size and position so that the
appearance is consistent across displays and works correctly in layout
exports.

Add lots of unit tests covering this.

#1 Updated by Michael Mächler over 2 years ago

Additional remark:
In a more complex map, it seemed the trick with changing the rendering settings of the map in the Item Properties section to Darken would not work. I do have a raster-layer on top of everything. If I deactivate this layer, the Annotations are correctly scaled.
I hope this helps to find the bug.
Thank you! :)

This is happening in QGIS 3.2.3 on macOS, as well. In 2.18.x, it seemed to work reliably in Windows, at least, but it is also now problematic there as well on macOS.

#5 Updated by vassilis fasoulas over 1 year ago

We can't switch to v.3 from 2.8 due to this issue.
A lot of drawings have print layouts with annotations so is impossible to print.
Please correct this annoying issue

This really limits what you can do with customizing maps. I guess we have to go back to an old version as well.
