[QGIS-Developer] QGIS Upgrade/Update Inquiry
Hi Team, I work for an IT service provider in Australia and we are working with a client that uses QGIS. The client is requesting for their QGIS to be updated/upgraded to the latest version. Just wanted to check if there is anything we need to take note when doing the update/upgrade. User is worried about compatibility issues. If there is none, are we good to just directly install the latest version on server for all users to have updated version of the software? Appreciate your response on this. 😊 Regards, John -- John Bingco TECHNICIAN ELEVATE TECHNOLOGY Mackay, Brisbane, & Newcastle P: 1300 463 538 W: www.elevate.com.au ___ QGIS-Developer mailing list QGIS-Developer@lists.osgeo.org List info: https://lists.osgeo.org/mailman/listinfo/qgis-developer Unsubscribe: https://lists.osgeo.org/mailman/listinfo/qgis-developer

[QGIS-Developer] QgsProcessingLayerPostProcessorInterface and Layers Legend Icon
I have several plugin functions that are
using QgsProcessingLayerPostProcessorInterface to style the layer after it
is created in a processing algorithm. I have largely ignored the fact that
after I style it, the legend displayed in the layers panel is its old style
and not the new one. I have a solution, but don't know if I am violating
some thread safe rule. I know I cannot use iface in the algorithm, but is
it safe to use in QgsProcessingLayerPostProcessorInterface?
In the top of my algorithm I import the following:
from qgis.utils import iface
In the processAlgorithm function I have the following.
if context.willLoadLayerOnCompletion(dest_id):
context.layerToLoadOnCompletionDetails(dest_id).setPostProcessor(StylePostProcessor.create(settings.lineColor,
settings.fontColor))
return {self.PrmOutput: dest_id}
My QgsProcessingLayerPostProcessorInterface looks like this. Notice the
line iface.layerTreeView().refreshLayerSymbology(layer.id()) which
effectively does what I need it to do. It works, but is safe or is there a
better way to do this? The output layer is a polygon in which I only want
the outline displayed. I am passing some color parameters from
processAlgorithm.
class StylePostProcessor(QgsProcessingLayerPostProcessorInterface):
instance = None
line_color = None
font_color = None
def __init__(self, line_color, font_color):
self.line_color = line_color
self.font_color = font_color
super().__init__()
def postProcessLayer(self, layer, context, feedback):
if not isinstance(layer, QgsVectorLayer):
return
sym = layer.renderer().symbol().symbolLayer(0)
sym.setBrushStyle(Qt.NoBrush)
sym.setStrokeColor(self.line_color)
* iface.layerTreeView().refreshLayerSymbology(layer.id
())*
# Hack to work around sip bug!
@staticmethod
def create(line_color, font_color) -> 'StylePostProcessor':
"""
Returns a new instance of the post processor, keeping a reference
to the sip
wrapper so that sip doesn't get confused with the Python subclass
and call
the base wrapper implementation instead... ahhh sip, you wonderful
piece of sip
"""
StylePostProcessor.instance = StylePostProcessor(line_color,
font_color)
return StylePostProcessor.instance

[QGIS-Developer] QGIS Server WMS Advertised extent and layers / groups bounding box in GetCapabilities
Hi QGIS Server devs, We, David and I, are working on enhancing the way QGIS Server is building the WMS GetCapabilities document. [1] And I have some questions about the QGIS Server WMS Advertised extent and the layers / groups bounding box in GetCapabilities. For exemple in the tests/testdata/qgis_server/test_project.qgs [2], the WMS Advertised extent is set to * CRS="EPSG:4326" minx="44.901236" miny="8.203154" maxx="44.901599" maxy="8.204165" [3][4] And in this project, the WGS84 extent of the landsat layer is * CRS="EPSG:4326" minx="30.151856" miny="17.924273" maxx="30.257289" maxy="18.045658" [5] As you can read, the layer landsat is out of the WMS Advertised extent. So the WMS GetCapabilities document contains a layer landsat with a bounding box outside the root layer / group bounding box. I was thinking that the root layer / group bounding box should include all the layers bounding box. So I wonder what the role of the WMS Advertised extent is. * Is it only the root layer / group extent ? * Is it a restricted extent (no data available outside this extent) ? * Is it the minimum extent of all WMS layers ? 1. https://github.com/dmarteau/QGIS/tree/wms-getcapabilities-refactoring-2 2. https://github.com/qgis/QGIS/blob/master/tests/testdata/qgis_server/test_project.qgs 3. https://github.com/qgis/QGIS/blob/master/tests/testdata/qgis_server/test_project.qgs#L1818 4. https://github.com/qgis/QGIS/blob/master/tests/testdata/qgis_server/wms_getcapabilities_rewriting.txt#L114 5. https://github.com/qgis/QGIS/blob/master/tests/testdata/qgis_server/wms_getcapabilities_rewriting.txt#L160 Thanks René-Luc Dhont___ QGIS-Developer mailing list QGIS-Developer@lists.osgeo.org List info: https://lists.osgeo.org/mailman/listinfo/qgis-developer Unsubscribe: https://lists.osgeo.org/mailman/listinfo/qgis-developer

Hi Raymond
The general idea is that for every PyQGIS module (e.g. "core") there is
a compiled python module (e.g. _core.so) and a directory acting as a
module ("core") which imports the compiled module and adds some extra
functionality (docstrings and more). So normally one wants to use import
qgis.core instead of qgis._core.
Now with the 3d module things are not so great, because "3d" is not a
valid module name because of the leading digit, so import qgis.3d simply
won't work. There are some ways to work it around [1], but I wouldn't
recommend using them. But as stated earlier, importing qgis._3d should
generally do the job.
It is probably worth creating a ticket to address this, but I am not
sure how to best fix it - probably the whole module should be renamed so
avoid the leading digit - e.g. "threed"

While trying to import a 3D class in a python script, I found out that
the code in the pyqgis docs is not working (for me):
from qgis.3d import QgsLayoutItem3DMap
Instead I need to add an underscore for the 3d module name:
from qgis._3d import QgsLayoutItem3DMap
Should this be fixed in the documentation? I'm not all sure, cause when
trying to fix it, I found this related commit:
https://github.com/qgis/pyqgis/commit/1ac564790aa0b7abbd003c04d07358d8e4f14493
This is the page in the docs:
https://qgis.org/pyqgis/master/3d/QgsLayoutItem3DMap.html
Should I make an issue? It took me a while to figure out that _3d
solution.
Cheers,
Raymond
