- GraphicsItem.pixelVectors copies cached results before returning
- Multiprocess fixes for Windows:
- mmap/shm uses anonymous maps rather than tempfiles
- avoid use of getppid and setpgrp
- work around hmac authentication bug (use os.urandom to generate key)
- AxisItem shows fewer tick levels in some cases.
- Lots of boundingRect and dataBounds caching
(improves ViewBox auto-range performance, especially with multiple plots)
- GraphicsScene avoids testing for hover intersections with non-hoverable items
(much less slowdown when moving mouse over plots)
Improved performance for remote plotting:
- reduced cost of transferring arrays between processes (pickle is too slow)
- avoid unnecessary synchronous calls
Added RemoteSpeedTest example
- fixed example testing script
- Added finer axis ticks back in some instances
- fixed improper bounds caching in log/fft mode
- fixed exception handling in remoteproxy
- AxisItem shows 2 tick levels instead of 3
- Lots of boundingRect and dataBounds caching
(improves ViewBox auto-range performance, especially with multiple plots)
- GraphicsScene avoids testing for hover intersections with non-hoverable items
(much less slowdown when moving mouse over plots)
These are deep changes; need good testing before we release them.
- Added documentation on export system
- Added flowchart documentation and custom node example
Bugfixes:
- prevent PlotCurveItem drawing shadow when unnecessary
- deprecated flowchart.Node.__getattr__ -- causes too many problems.
- SVG export text elements use generic font-family as backup, corrected item transformation issues
- Fixed RuntimeError caused when clearing item hierarchies from ViewBox
- Fixed example execution bug
Packaging maintenance:
- Added missing files to MANIFEST.in, fixed setup.py package detection
- Added debian control files for building source packages
- Fixed version numbering in doc, __init__.py
- GLScatterPlotItem can work with arbitrarily-shaped vertex arrays
- added colorToAlpha function
Bugfixes:
- GraphicsScene emits sigMouseClicked for all clicks
- CanvasItem emits transformation change signal when mirrored
- GLViewWidget.pixelSize correctly handles position specified as array
- SRTTransform3D assumes Zscale=1 when converting from 2D transform
- Canvas: added per-item context menus
- Isocurve:
option to extend curves to array boundaries
option to generate QPainterPath instead of vertex array
- Isosurface is a bajillion times faster
- ViewBox
added clear() method
added locate(item) method (shows where an item is for debugging)
Bugfixes:
- automated example testing working properly
- Exporter gets incorrect source rect when operating on PlotWidget
- Set correct DPI and size for SVG exporter
- GLMeshItem works properly with whole-mesh color specified as sequence
- bugfix in functions.transformCoordinates for rotated matrices
- reload library checks for modules that are imported multiple times
- GraphicsObject, UIGraphicsItem: added workaround for PyQt / itemChange bug
- ScatterPlotItem: disable cached render during export
Other:
- added documentation for several functions
- minor updates to setup.py
