Re: [Qgis-user] Symbol lines every km, moving when changing scale or moving map

Hi, Not sure if/how I can help on this benchmark. If I understand well you want to know if disabling the simplification on the marker line symbol layer only would make a huge difference or not on rendering performance. But as far as I saw the option is only available for the whole layer at the

Hi Jérémie, Ah good to hear! I'm not a big fan of this fact that line simplification is turned on by default in QGIS. I believe that users should consciously turn it on if they want it! Your example shows that it can lead to confusion (understandably). Good that it works now. Note that you

Hi, I had simplification turned on, indeed... I deactivated it : - in the Options as you mention, so that it is deactivated for newly added layers - in my layer options (Rendering properties) And it is ok now. It makes sense that if the line is simplified the distance vary ! Thanks Andreas.

Hi Jérémie, Do you have geometry simplification turned off? See "Settings" --> "Options" --> "Rendering" --> "Enable feature simplification ..." Make sure this is deactivated (I think it is enabled by default). Greetings, Andreas On 2021-02-19 11:05, Prud'homme Jérémie wrote: Tested too

Tested too fast :( Behavior is ok when zooming in, but still problems when zooming out (whereas the entire feature is visible !). See here : https://www.zupimages.net/viewer.php?id=21/07/ehlo.gif Circles should follow the strokes generated with the tool "Points along geometry". Jérémie. Le

Hi, Thank you very much Nyall, this one was pretty well hidden. With clipping unchecked, behavior is as expected for my use case. Jérémie. Le jeu. 18 févr. 2021 à 23:29, Nyall Dawson a écrit : > On Wed, 13 Jan 2021 at 06:33, Prud'homme Jérémie > wrote: > > > > Hi, > > > > I'm using QGIS

A more 'permanent' workaround would be to densify the lines and then place a symbol on every vertex, including or not the ones at the extremities. Alex Le jeu. 18 févr. 2021 à 12:07, Raymond Nijssen a écrit : > Yes, I recognize that behaviour. I think QGIS cuts the line at the map > canvas

Yes, I recognize that behaviour. I think QGIS cuts the line at the map canvas border and starts calculating point locations from the cut off point. Probably to prevent calculating all points outside the map that won't be visible anyway. This is good when you just want a hatched line or a row

Hi, I'm using QGIS 3.10. I tried to use only symbology to display a stroke every km along a road. The project CRS is 2154 (Lambert 93). When adding a ""symbol line" with an interval of 1000 map units (meter for 2154) – or 1000 meters at scale, same result – I achieve to display symbols every
