Re: [Qgis-user] MrSID on QGIS 2.6.,1, Mac OSK 10.10.1

Check my site.  The GDAL framework that you should have installed also has a 
separately downloadable plugin for the MrSID format.

Re: [Qgis-user] MrSID on QGIS 2.6.,1, Mac OSK 10.10.1

[Randal Hale]

I think back when 1.8 was out there was a package to read Sid Files (I'm 
on linux currently).


I've fallen back to using http://www.lizardtech.com/downloads/category/ 
-> Geoexpress Command line utilities to decode sid to geotiff.


Not sure exactly how you could do that on a mac - maybe build a 
linux/windows VM to do the decompression. I hope at some point sid 
becomes available again - I wished I had to skill to make that happen.

Re: [Qgis-user] Map Composer and Attributes from a layer

[Randal Hale]

A

I'm moving a project from ArcGIS Data Driven Pages into QGIS. I'm not 
sure if Data Driven Pages was the best way to do it originallyand 
that's why I was shying away from Atlas when Alexandre brought it up


Now I've got two choices when I had none.

Good People - Thank you.

Nyall - Thanks for all the stuff you're doing in Composer.

Atlas IS the correct way - it's not a workaround ;). However, if
you're after an expression, then use a combination of getFeature and
attribute. This is how it works:

First, use getFeature to find a matching feature from a layer:
getFeature( 'my_layer', 'id_field', 5)
This will return the feature from "my_layer" with the attribute
"id_field" equal to 5.

Next, chain this into attribute:
attribute( getFeature( 'my_layer', 'id_field', 5) , 'feature_name')

This will return the value stored in the attribute "feature_name" from
the matching feature from "my_layer".

Hope that helps!

Re: [Qgis-user] recurrent PythonError. What is wrong?

[Enrico Ferreguti]

I think you installed the plugin without having blank project. existing
layers were not registered to the plugin that try to hooks to change layer
signals (fired on every event you describe)
I would try to close your current project before reinstall plugin or simply
restart qgis after install it.

Hello Randal,

You are looking for the atlas generation feature.

In the map composer go to the atlas tab and set your layer as atlas 
coverage layer. (Don't forget to turn atlas control on your map item 
properties). From that point on, you can use the coverage layer's 
attributes in labels usig the expression builder, or simply set the 
label as:


[%my_column%]

Hope I helped.

Although I note that numpy is in the complete framework.
The reason I mention it is that if someone actually did read the readme, then 
they might find themselves wondering why the website just says the complete
