Contains framework for multithreaded operations on QImages, and
numerous operations such as grayscale, hue/saturation, brightness/
contrast modification, flip, blur, distance transform, alpha
modification and color overlays.
The maintenance of three R-trees was too complicated, using a lot of memory
and the performance benefit was questionable :)
The approach with just one R-tree leads to much simpler code
Removed k-NN queries in the process - they were not used in QGIS code. They can be
reintroduced later, but there is not much use for them right now...
This currently just invalidates the whole trees. It would be more sophisticated to do just the updates
to the existing trees - but I run into various issues with the spatial index library when doing that.
So resorting to this for the moment.
There is a new check box that allows the user to tell whether a map should
keep the layer styles (it will store the state when the check box is checked).
The stored layer styles keep a snapshot of each layer's configuration
instead of just keeping name of the style.
This solves issues with styles and visibility presets in composer which were
not completely compatible.
This code has been funded by Tuscany Region (Italy) - SITA (CIG: 6002233F59)
and commissioned to Gis3W s.a.s.
- style manager is always enabled (client code does not need to distinguish between enabled/disabled state)
- layers currently active style is stored only in QgsMapLayer - in style manager it has entry with no data (avoids duplication of data)
This also solves issues with visibility presets and styles when some presets do not have stored style
[FEATURE] Support for multiple styles per map layer
Available in legend context menu in Styles sub-menu where it is possible to add/remove styles
and quickly switch between them.
In version 2.6, new keywords has been added to Expression :
* $currentfeature - returns the current feature
* $atlasfeature - returns the atlas feature
* getFeature - gets a matching feature from a layer
But I think, Expression lacks a few keywords :
* geometry - returns the feature's geometry
* transform - returns the transformed geometry
These new keywords can be used with getFeature for some geometry tests like
intersects, crosses, contains, etc
Tests has been added to geometry and transform in Expression
See http://hub.qgis.org/issues/11814
NOTE: the map rotation should likely be considered at LabelPlacement
configuration rather than at rendering time
Raises pixel mismatch tolerance for background labels tests
Includes widget to show and set map rotation.
Handle rotation in vector and raster renderers.
Ensure correct behavior of panning and zooming actions.
Drop compile-time defines for ARM and ANDROID, leaving only
the qreal based function to transform in place.
Update expected test results after eye comparison.
