* Add CLI args to video speed test for easier / automated benchmarking * use a buffer-qimage so we can avoid allocing so much this should improve performance under windows * playing with numba * oh, mins/maxes in the other order * maybe put the cupy in here and see what happens * pre-alloc for gpu and cpu * handle possibility of not having cupy * no numba in this branch * organize imports * name them after their use, not their expected device * cupy.take does not support clip mode, so do it explicitly * add CUDA option to the VideoSpeedTest * rename private attr xp to _xp * handle resizes at the last moment * cupy is less accepting of lists as args * or somehow range isn't allowed? what histogram is this? * construct the array with python objects * get the python value right away * put LUT into cupy if needed * docstring about cuda toolkit version * better handling and display of missing cuda lib * lint * import need * handle switching between cupy and numpy in a single ImageItem * only use xp when necessary we can now depend on numpy >= 1.17, which means __array_function__-implementing cupy can seamlessly pass into numpy functions. the remaining uses of xp are for our functions which need to allocate new data structures, an operation that has to be substrate-specific. remove empty_cupy; just check if the import succeeded, instead. * use an option to control use of cupy * convert cupy.ceil array to int for easier mathing * RawImageWidget gets to use the getCupy function now, too * raise error to calm linters; rename for clarity * Add Generated Template Files * document things better * cruft removal * warnings to communicate when cupy is expected but somehow broken * playing with settings to suss out timeout * playing with more stuff to suss out timeout * replace with empty list * skip test_ExampleApp on linux+pyside2 only Co-authored-by: Luke Campagnola <luke.campagnola@gmail.com> Co-authored-by: Ogi Moore <ognyan.moore@gmail.com>

Global Configuration Options
|
|
============================
|
|
|
|
PyQtGraph has several global configuration options that allow you to change its
|
|
default behavior. These can be accessed using the :func:`setConfigOptions` and
|
|
:func:`getConfigOption` functions:
|
|
|
|
================== =================== ================== ================================================================================
|
|
**Option** **Type** **Default**
|
|
leftButtonPan bool True If True, dragging the left mouse button over a ViewBox
|
|
causes the view to be panned. If False, then dragging
|
|
the left mouse button draws a rectangle that the
|
|
ViewBox will zoom to.
|
|
foreground See :func:`mkColor` 'd' Default foreground color for text, lines, axes, etc.
|
|
background See :func:`mkColor` 'k' Default background for :class:`GraphicsView`.
|
|
antialias bool False Enabling antialiasing causes lines to be drawn with
|
|
smooth edges at the cost of reduced performance.
|
|
imageAxisOrder str 'col-major' For 'row-major', image data is expected in the standard row-major
|
|
(row, col) order. For 'col-major', image data is expected in
|
|
reversed column-major (col, row) order.
|
|
The default is 'col-major' for backward compatibility, but this may
|
|
change in the future.
|
|
editorCommand str or None None Command used to invoke code editor from ConsoleWidget.
|
|
exitCleanup bool True Attempt to work around some exit crash bugs in PyQt and PySide.
|
|
useWeave bool False Use weave to speed up some operations, if it is available.
|
|
weaveDebug bool False Print full error message if weave compile fails.
|
|
useOpenGL bool False Enable OpenGL in GraphicsView. This can have unpredictable effects on stability
|
|
and performance.
|
|
useCupy bool False Use cupy to perform calculations on the GPU. Only currently applies to
|
|
ImageItem and its associated functions.
|
|
enableExperimental bool False Enable experimental features (the curious can search for this key in the code).
|
|
crashWarning bool False If True, print warnings about situations that may result in a crash.
