bool hit_test(double x, double y, double tol);
2. added image_view(unsigned x, unsigned y, unsigned width, unsigned height)
allowing to select region from image data e.g (in Python):
im = Image(2048,2048)
view = im.view(0,0,256,256)
save_to_file(filename,type, view)
3. changed envelope method to return vy value in datasource classes
4. features_at_point impl for shape and postgis plug-ins
rendering them as labels when using the text or shield symbolisers
(blame my horrible datasets)
* correctly recognise the Postgis "text" data type (it was in
postgisfs.cpp just not postgis.cpp) - my initial workaround to the
above was "SELECT trim(from label) AS label ..." which failed
miserably because it returned a text data type.
Thanks to Robert Coup for the patch!
2. added extra parameter 'estimate_extent'. By default, exact extent will be calulated e.g :
select extent(geom) from table_name;
Sometimes it is more practical (faster!) to use estimated extent
select estimated_extent('table_name','geom');
but it is somewhere around 95% accurate.
Usage:
....
params["estimate_extent"]="true";
....
