QString methods
Using single quotes is a significant performance boost. Rough
benchmarks indicate the QString single quote methods take
about 15% of the time the double quote variants take.
- use at() instead of [] for temporary containers (at() returns
const reference, so it avoids the detach which occurs with [])
- use at( 0 ) rather than first() for containers, because first()
detaches (Qt5 introduced constFirst()/constLast() to overcome this)
- Main C++ core and gui classes and desktop app integration
- Support for authentication method plugins
- Does not contain any integration with service connections
* .gitignore sort and remove duplicates
* show more warnings in tests
* add/update masks for rendering checks on windows
* fix delimited text provider tests
* disable QgsLogger and QgsPalLabelingServer on windows
This new tool in qgis_analysis library is able to take several rasters
as input and to align them perfectly, that means:
- reproject to the same CRS
- resample to the same cell size and offset in the grid
- clip to a region of interest
- rescale values when required
...rather than reading input layers directly through GDAL.
Benefits include more robust handling of nodata/data type conversions,
less code duplication, also being able to take advantage of features
in QGIS raster code like handling gain/offset in rasters. (fix#12450)
Also, add a choice of output projection to the raster calculator.
Previously the output CRS would be taken from the first raster, with
no guarantees that the output extent matched the output CRS. This
resulted in empty/misplaced rasters. (fix#3649)
...for more accurate calculations (fix#9081)
Also:
- Add test suite for raster calculator
- Fix errors with log/log10 calculation and inputs <= 0
- Fix loss of nodata values in certain circumstances
The idea is to replace the current OSM provider+plugin by this new code. Differences from old code:
- read-only access - without editing and upload support
- no special provider (using SpatiaLite provider)
- underlying OSM topology accessible from API
- download using Overpass API: fast, customizable, nearly unlimited download
- OSM XML files have to be first imported to a Sqlite3 database, then SpatiaLite layers can be exported
- No longer a need for hard link
- Build directory app bundle, providers, Python plugins and unit tests functional
- Adjusted resources corrected on install
