Re: [Qgis-user] Problem to open Raster files

2021-02-21 Thread Nicolas Cadieux 
Hi,

Did you unzip the files?  If not, unzip the folder first, then access the 
files. Windows can unzip archives but my personal preference in 7zip.

 seems this a ESRI File Geodatabase (sorry, left the ESRI stage 10 years

 ago, so not sure).



 As far as I know, rasters can't be exctracted from this with QGIS.

 could you possibly share a little more details about what type of  
rasters you are dealing with? There is a bazillion of different  
raster formats!

Hi J?r?mie,



 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!


I'd be interested to see some benchmarks of disabling vs enabling

 simplification for the marker line symbol layer alone. If it's not too

 expensive, we could skip it automatically for line marker symbol

 layers (it makes a HUGE difference to the rendering speed for simple

 line layers and other symbol layer types, but the intention is that

 the results should be visually identical to no simplification).



 Nyall


Your example shows that it can lead to confusion (understandably).



 Good that it works now. Note that you can override this setting on  
a per layer base in the layer properties - so not all layers need  
to have the same setting.




 Greetings,



 Andreas

 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 J?r?mie,



 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).
