An item should call this method if it cannot handle the event. This will allow the event to be delivered to other items.

Create and return an :class:`ImageView <pyqtgraph.ImageView>` Will show 2D or 3D image data. Accepts a *title* argument to set the title

Show the position, pixel, and value under the mouse cursor.

Convert a QImage into numpy array. The image must have format RGB32, ARGB32, or ARGB32_Premultiplied. By default, the image is not copied; ch

Initialize items that were not initialized during addItem().

Parameters ---------- args : numpy.ndarray series of 1D numpy arrays of the same length and dtype Returns ------

Get the transform mapping local coordinate system to image array. :meta private: Returns ------- :class:`QT

Return a QTransform that is the inverse of *tr*. A pseudo-inverse is returned if tr is not invertible. Note that this function is preferr

Return the index of refraction for *glass* at wavelength *wl*. The *glass* argument must be a key in self.data.

Returns `True` if the gradient has exactly two stops in it: Black at 0.0 and white at 1.0.

Return True if this parameter type matches the name *typ*. This can occur either of two ways: - If self.type() ==

Replacement for os.path.isdir that works in frozen environments.

Generate isosurface from volumetric data using marching cubes algorithm. See Paul Bourke, "Polygonising a Scalar Field" (http://paulbou

Return the bounding rect of the item in view coordinates

Return the item and column corresponding to a QModelIndex.

Return a list of the items displayed in the region (x, y, w, h) relative to the widget.

This routine should capture key presses in the current view box. Key presses are used only when mouse mode is RectMode The fo

Return the previous position of the mouse in the coordinate system of the item that the event was delivered to.

Return the scene position of the mouse immediately prior to this event.

Return the screen position of the mouse immediately prior to this event.
