* Added HDF5 exporter
* CSV exporter gets (x,y,y,y) export mode
* Updates to SVG, Matplotlib exporter
* Console can filter exceptions by string
* Added tick context menu to GradientEditorItem
* Added export feature to imageview
* Parameter trees:
- Option to save only user-editable values
- Option to set visible title of parameters separately from name
- Added experimental ParameterSystem for handling large systems of
interdependent parameters
- Auto-select editable portion of spinbox when editing
* Added Vector.__abs__
* Added replacement garbage collector for avoiding crashes on multithreaded Qt
* Fixed "illegal instruction" caused by closing file handle 7 on OSX
* configfile now reloads QtCore objects, Point, ColorMap, numpy arrays
* Avoid triggering recursion issues in exception handler
* Various bugfies and performance enhancements
- 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 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.
- Image exporter detects GraphicsView background color
- Corrected exporter filename handling for SVG export
- ViewBox no longer attempts to deregister itself while python is exiting
- Speedup for conversion using np.array(MetaArray_instance)
- GLGraphicsItem updates immediately when its GL options have changed
- Corrected some GL shader program bugs for nVidia drivers
- Fixed coordinate mapping bug in functions.transformCoordinates
- Fixed PySide import error
- generalized makeARGB API: can now process arrays of arbitrary shape.
- affineSlice automatically converts vector arguments to array
- new function applyLookupTable taken from makeARGB
- isosurface function returns array
Updated VideoSpeedTest example to follow new makeARGB API
LayoutWidget: row argument now accepts 'next' as value
ParameterTree bugfix: avoid infinite recursion when accessing non-existent attributes
ViewBox: avoid exit error caused when cleanup callback is invoked while python is shutting down
- documentation updates
- PlotItem informs all items when switching to log mode
- GradientEditorItem has sigGradientChangeFinished
- ParameterTree list types check linits on initialization
- Fixed RuntimeError in TreeWidget.clear()
- fixed handling of foreground colors in AxisItem
- fixed rare crash caused in AxisItem
- fixed improper propagation of key events from SpinBox
- many others
- Fixed some floating-point precision issues. (Added a workaround for QTransform.inverted() bug)
- No longer putting asUnicode inside __builtin__ since this causes problems in some rare circumstances
(pyshell, lazy import recipe)
- Minor docstring updates
- Added pyqtgraph.systemInfo() for bug reporting
- GraphicsLayout does a better job of avoiding occupied cells when using automatic placement
- Fixed sizing issues with LabelItem
- Updated GraphicsLayout example
- ForkedProcess is much more careful with inherited state -- closes file handles, removes atexit and excepthook callbacks
- Remote processes copy sys.path from parent
- Parallelizer has ProgressDialog support
- Many docstring updates
- Added some test code for remote GraphicsView rendering
- fixed AxisItem sometimes drawing the same tick twice (sometimes with different text)
- fixed handling of record arrays in setting ScatterPlotItem point data
- optional context menu for ImageItem
- inverted y-axis in Canvas (+y now points upward)
- extra __init__ arguments for Dock
- Transform can be constructed from Matrix4x4
- many others
Flowchart updates - added/fixed some display nodes
Merge from Kratz:
- documentation updates
- ComboBox class (updateList() allows entire item list to change while remembering previous setting)
