Hi, I found two ways of doing that, I think the second is faster but not sure. (And I think they will both be slower than the random order code you were using before, but the order will remain.) Good luck, Raymond --- layer = iface.activeLayer() ids = layer.selectedFeatureIds()

Re: [Qgis-user] Raster calculator

Hi Jocelyn, Sorry for not knowing the entire answer, but here are some steps. 1. Select all cells that are not white using the Raster Calculator: "test@1" != 255 or "test@2" != 255 or "test@3" != 255 2. Set all 0 values to nodata with GRASS r.null 3. This is where I'm stuck too. :( You

Hi, Are you sure you exported your layer to a shapefile, after opening the csv as a layer? Cause QGIS cannot edit a csv attribute table. Raymond On 24-04-19 09:43, Boaz Bar Ilan wrote: hi I imported  data csv file to an shapefile I cant  edit its attribute table is there a way to unlock

Re: [Qgis-user] Using python on qgis Forms

Hi Kyle! The python code to get all the id's looks like this: ids = [] for feat in iface.activeLayer().getFeatures(): ids.append(feat.id()) print(ids) Now you need to connect your button to a function containing the above code, something like:

Re: [Qgis-user] symbolize points by their size and category

Hi Alejandro, You could do the color by a "categorized" symbol (as usual) and the size based on a "data driven override" with an expression calculating your attribute values to symbol sizes. Good luck, Raymond On 01-02-19 11:50, Alejandro Chamizo de Castro wrote: Hello colleagues, do you

Hi Marian, As I understand you want to set every symbol in your rule based classification to 80% transparent (instead of the entire layer)? I tried to write a qgis (v3.4) script but unfortunately it crashes my qgis. So I hope somebody here can correct it, or maybe you will find the solution

Re: [Qgis-user] about distance calculation

Hi Mahmut, Reading your question I wonder if you really want to know the distance to the railroad (line) or to the stations (points). Since you usually cannot enter or leave the train at any location along the railroad. Anyway, qgis can calculate both with processing algorithms: 1. distance

Re: [Qgis-user] how does QGIS generate the EPSG from a Shapefile?

As far as I know, qgis cannot discover it. If the shapefile is missing the projection info, it will either: 1. Ask you to select it 2. Select the one your current map is set to 3. Select a predefined epsg depending on your settings. If your settings are 2. or 3. you might not notice this, and

Re: [Qgis-user] Json and QGIS

Hi Xristos, Not sure if I understand your question correctly. Geojson is a vector format, so you cannot add raster data this way. If you want to add a raster layer, it is very similar: https://docs.qgis.org/testing/en/docs/pyqgis_developer_cookbook/loadlayer.html#raster-layers Hope this
