[Qgis-developer] Problems with Atlas and Map dimensions on composer using Python

[Stott James]

Hi all,

Is anyone else having problems with using atlas with python?

I am writing some python code that uses the Atlas functionality in master to create a PDF / jpg for each of my 5000 records.

I can produce a jpg/pdf for each feature, however the composerMap object does not stay the same size.

I found this bug report which describes the issue. This report is listed as fixed:

http://hub.qgis.org/issues/6956

I have set the following two lines in my code:

myAtlas.setFixedScale( False )
myAtlas.setMargin(0.1)

If I set this up from within QGIS, it works perfectly. It is only through Python I have problems.

Here are the example exported jpgs:

I have also included a stripped down version of my code, along with a sample shapefile (this isn't the data I am planning to use it with, but it doesn't work with either the sample or the real data).

Using master, updated today from OsGeo4W.

Many thanks,
