[Qgis-user] The epsg code in the qgis project.

[João Gaspar]

Hi Andrea,

adapt this code:
crs=iface.mapCanvas().mapSettings().destinationCrs() print crs.authid() +'
- '+ crs.description()

I wrap this in a function that retrieve the espg from a qgis project
inside of a label in the composer.


from qgis.utils import ifacefrom qgis.core import *from qgis.gui
import *@qgsfunction(args=0, group='CRS')def crslabel(value1,feature,
parent):    """    Returns the project CRS         <h4>Syntax</h4>
<p>crslabel(<i>value</i>)</p>    <h4>Arguments</h4>    <p><i>none</i>
→ 0</p>    <h4>Example</h4>    <p><!-- Show example of
function.-->    crslabel → EPSG:4326 - WGS84</p>
<h4>Note:</h4>    <p>This function only produces the EPSG code and the
description.    </p>    """
crs=iface.mapCanvas().mapSettings().destinationCrs()    return
crs.authid() +' - '+ crs.description()

In this function give me in a string the espg code and de description.


Regards
João
