[QGIS-Developer] WMTS/XYZ on high DPI screens

Hi all Whenever I use a background map like OpenStreetMap on my high-res laptop screen (192 DPI) in QGIS, the labels are tiny. That is "natural" because tiles are made for screens with ~96 DPI where the size of labels is just fine. When I look at OSM tiles in the browser, I can see that the browse

Re: [QGIS-Developer] Is it just me, or is sip totally broken?

Hi Nyall I have seen that too with other QGIS registries, but I am not sure if it is actually broken in SIP or if this should be simply handled in a different way. My understanding is that SIP for an object has the "c++ part" and "python part". If we do not deal with subclasses, things seem to wo

Hi Hugo Are the issues you mentioned solved now by your PR https://github.com/qgis/QGIS/pull/8724 or that was some other separate issue? For your open question with "click first" behavior of vertex tool as an option - I don't know. There has been some interest to address some ergonomic issues in

[QGIS-Developer] Dealing with datum shift grids in QGIS

Hi all Recently I needed transformation between points from high-accuracy GPS to British National Grid (EPSG:27700) which involves datum shift (WGS 84 to OSGB 1936) using OSTN15 grid. The process to do that with QGIS is currently... well... really clumsy. One needs to: 1. manually download grids

Re: [QGIS-Developer] Error with hdf5.dll on Windows build.

Hi Nathan It looks like the CMake module to find HDF library is picking hdf5.dll instead of hdf5.lib import library for some reason. Maybe as a workaround you can manually set the HDF5_C_LIBRARIES variable to the correct .lib file. We are using the standard CMake module to find HDF, so if this iss

[QGIS-Developer] Python API for 3D

Hi all I have been thinking it would be good to finally have Python API also for qgis_3d library. Until now I have kept the 3D library intentionally without Python bindings so that it is possible to move the code around without being blocked by the API stability requirement. I think for the time
