Re: [Qgis-developer] QGIS server ignores optional SVG symbols path
I guess the issue was resolved. Look at this tickets. http://hub.qgis.org/issues/10327 and this http://hub.qgis.org/issues/8664 You should define one or more environment variables. for path. We use this approach succesfully. A.

Re: [Qgis-developer] Plugins mandatory metadata
Sorry, I accidentally didn't send it the to qgis-community-team ML initially. Who could fix it? I'm not familiar with the webpage stuff.

Re: [Qgis-developer] WMS uncorrect rendering using "Simple Rendering" method
created a simple script isolating the rendering phase reveal that the
problem seems internal to the plugin
thank you
Luigi Pirelli (luigi.pire...@faunalia.it - lui...@gmail.com)
this script works
from PyQt4.QtCore import *
from PyQt4.QtGui import *
wms=QgsRasterLayer("crs=EPSG:3003&format=image/png&layers=rt_ofc.10k13&styles=&url=http://www502.regione.toscana.it/wmsraster/com.rt.wms.RTmap/wms?map%3Dwmsofc%26";,
"nome", "wms")
QgsMapLayerRegistry.instance().addMapLayers([wms])
# create image
size = QSize(800,600)
img = QPixmap(size)
img.fill(QColor(255, 255, 255, 255))
mainCanvas = iface.mapCanvas()
extent = mainCanvas.extent()
mainRenderer = mainCanvas.mapRenderer()
mapRenderer = QgsMapRenderer()
mapRenderer.setOutputSize( size, img.logicalDpiX() )
mapRenderer.setDestinationCrs( mainRenderer.destinationCrs() )
mapRenderer.setMapUnits( mainRenderer.mapUnits() )
mapRenderer.setProjectionsEnabled( mainRenderer.hasCrsTransformEnabled() )
layerIds = [wms.id()]
# set layer set
mapRenderer.setLayerSet(layerIds)
mapRenderer.setExtent(extent)
extent.scale( float(1000) / mapRenderer.scale() )
render.setExtent(extent)
# create painter
p = QPainter()
p.begin(img)
# do the rendering
mapRenderer.render(p)
p.end()
del p
mapRenderer.deleteLater()
del mapRenderer
# save image
img.save("/tmp/render.png","png")

Re: [Qgis-developer] Regarding linear transformation in Georeferencer
Dear Sajid, checking the source of the plugin I realized that different scales are used in easting and northing direction. So the formulas look like: E' = Eoffset + Escale * E N' = Noffset - Nscale * N The minus in N formula is because of the different axis direction in the screen coordinates and map coordinates. The four unknowns are calculated from a least squares estimation. Regards, Zoltan On Wed, 13 Aug 2014, sajid pareeth wrote: Hi Zortan Thank you for the reply. Would be great to know, how this Offsets and scale is calculated from a set of GCP's. Any idea?
