I am having a bit trouble migrating a script to QGIS 2.2.<br>
<br>
In QGIS 2.0 I have the following Python script which will load a composer<br>
from template, generate an atlas and export to image.<br>
<br>
myFile = os.path.join(os.path.dirname(__file__), template)<br>
myTemplateFile = file(myFile, 'rt')<br>
myTemplateContent = myTemplateFile.read()<br>
myTemplateFile.close()<br>
myDocument = QDomDocument()<br>
myDocument.setContent(myTemplateContent)<br>
myComposition.loadFromTemplate(myDocument)<br>
<br>
# Get map composition and define scale<br>
myAtlasMap = myComposition.getComposerMapById(0)<br>
myAtlasMap.setNewScale(int(scale))<br>
<br>
# Setup Atlas<br>
myAtlas = QgsAtlasComposition(myComposition)<br>
myAtlas.setCoverageLayer(atlas_desktop)<br>
myAtlas.setComposerMap(myAtlasMap)<br>
myAtlas.setFixedScale(True)<br>
myAtlas.fixedScale()<br>
myAtlas.setHideCoverage(False)<br>
myAtlas.setFilterFeatures(True)<br>
myAtlas.setFeatureFilter("reference = '%s'" % (str(ref)))<br>
myAtlas.setFilterFeatures(True)<br>
print myAtlas.composerMap()<br>
<br>
# Generate atlas<br>
myAtlas.beginRender()<br>
for i in range(0, myAtlas.numFeatures()):<br>
myAtlas.prepareForFeature( i )<br>
jobs = r"\\myserver\a folder\Jobs"<br>
job_fol = os.path.join(jobs, str(ref))<br>
if not os.path.exists(job_fol):<br>
os.makedirs(job_fol)<br>
output_jpeg = os.path.join(job_fol, ref + "_BMS_plan.jpg")<br>
myImage = myComposition.printPageAsRaster(0)<br>
myImage.save(output_jpeg)<br>
myAtlas.endRender()<br>
if os.path.isfile(output_jpeg) is False:<br>
QMessageBox.warning(self.iface.mainWindow(), "Uh Oh!",<br>
"Something went wrong, no image exported!")<br>
return<br>
else:<br>
return<br>
<br>
In QGIS 2.2 this script is no longer working correctly. The template is<br>
loaded and a map is exported to image, however, the map does not display the<br>
correct area. The map area draws the correct layers but the extent is wrong<br>
(no where near the feature from the atlas). Had a look at the documentation<br>
and wasn't really able to see what has changed/deprecated?<br>
<br>
Thanks<br>
