Significant performance issues have been identified with np.clip
and thus clip_array was created to speed up the operation. In addition
clip_scalar was created to clip a scalar value between two other values
this commit replaces many uses of np.clip from operating on scalars to
using clip_scalar instead
Using numpy methods that are intended for vectorized operations is
substantially slower than using the math module, so when feasible the
math module methods should be used.
When running on macOS Big Sur, pyopenGL is unable to find the bindings
Previously this was assumed that it would be fixed in later versions
of Python 3.8, but that has not happened.
* Initial implementation of ColorBarItem
* initial commit
* fixed missing indent
* docstring extension and corrections
* Converted example to match others / run as part of tests
* load local color maps instead of importing from colorcet
* clean up window creation code
* horizontal color bar and clean-up
* switched to mkQApp initialization
* cleaned up some comments
random.normal() generates as float64 and gets converted to a smaller
dtype. generating all the needed data in a single call thus uses a lot
more memory than is necessary.
this changes it such that smaller chunks are generated.
data clipping is also changed to be in-place.
the gaussian filtering which gave the video a washed-out look is also
removed. this also contributed to data generation time.
the Example App allows the user to choose a binding and a graphics
system to use to execute an example.
issue 1: setGraphicsSystem is obsolete and the method no longer exists.
thus selecting a graphics system causes an error.
issue 2: the choice of binding to use is passed as an extra command
line argument to be parsed by initExample. this is problematic for
examples that use argparse, such as VideoSpeedTest.py
issue 3: if the user has set PYQTGRAPH_QT_LIB, that takes precedence
over the choice made in the Example App.
this patch fixes the above 3 issues by setting PYQTGRAPH_QT_LIB in
the child process' environment and removing the old parsing of the
command line arguments
* feature TriangleROI
Added equilateral TriangleROI.
getArrayRegion is not working yet
* show off (and implicitly test) our new TriangleROI
* the PolyLineROI.getArrayRegion can be used by TriangleROI
refactor the actual logic to live on ROI
* refactors for readability
* variable names
* lint
* docstring type and purpose

* Fix ScatterPlotItem performance regression
* Add hover benchmark to ScatterPlotSpeedTest.py
* Removed a performance regression from GraphicsView
* Removed some tests failing due to the last commit
* LegendItem: fix spelling mistake
* LegendItem: remove unused curRow variable
* LegendItem: correct calculation of rowCount
Previously, rowCount would never be updated unless setColumnCount()
was called. This fixes that issue.
It also fixes that setColumnCount() rounded down (floored) the
number of rows, instead of providing an accurate number:
e.g. 4 items in 3 columns would yield rowCount=1, when it should be 2
* LegendItem: remove rowCount argument (not implemented)
Logic to actually use the rowCount argument was not implemented.
Users might expect rowCount to limit the number of rows to e.g. 1,
but that is not what the current code does (it only works with limiting
the number of columns).
Thus, we were exposing an unused/misleading parameter to users.
This can and should be reverted if the logic for limiting the number
of rows is added.
* LegendItem: add colCount docs
* test (LegendItem): remove unused curRow variable
* test (LegendItem): check increasing rowCount as add items
* Fixed logic in placement of items in legend with multiple columns
* Actual row count here should be 2, not 3

fix BufferError: cannot close exported pointers exist
for some reason, even though the ctypes object falls out of function
scope, it causes a lingering reference.
in any case, the use of ctypes is no longer necessary.
Don't change temporary files mid-way for Darwin
This fixes the CI issues on Darwin.
close the remote process on app shutdown.
* set environment variables before starting QApp
* fix-422
* Better support of hidpi
* Fix Typo in App-Name
* Remove fontScaleFactor bits
* Add documenation for hidpi displays
* Fix pg not defined
* set environment variables before starting QApp
* fix-422
* Better support of hidpi
* Fix Typo in App-Name
* Remove fontScaleFactor bits
* Add documenation for hidpi displays
* fix: delete generated designerExample_*.py files
designerExample.py loads designerExample.ui directly
* remove unused examples/utils.py
* add almost all examples in folder
* use mkQApp and don't set style nor palette
not needed for an example and also avoids a PyQt6 6.0 refcount bug in
app.setStyle()
* bold interesting examples
* test_examples.py needs to know about Namespace too
* Revert "remove unused examples/utils.py"
This reverts commit 2eddead459.
* categorize examples lists in utils.py
skip tests that don't work for Qt6
add Qt6 and remove Qt4 from test_examples.py
update README.md
switch mouse tests to use QPointF
this eliminates all the special casing for different bindings
