Implements many features: * Displays 2D and 3D image data. For 3D data, a z-axis slider is displayed allowing the user to select which frame is displayed. * Displays histogram of image data with movable region defining the dark/light levels * Editable gradient provides a color lookup table * Frame slider may also be moved using left/right arrow keys as well as pgup, pgdn, home, and end. * Basic analysis features including: * ROI and embedded plot for measuring image values across frames * Image normalization / background subtraction Basic Usage:: imv = pg.ImageView() imv.show() imv.setImage(data) **Keyboard interaction** * left/right arrows step forward/backward 1 frame when pressed, seek at 20fps when held. * up/down arrows seek at 100fps * pgup/pgdn seek at 1000fps * home/end seek immediately to the first/last frame * space begins playing frames. If time values (in seconds) are given for each frame, then playback is in realtime. c tjj||g| d|_d|_d|_||_d|_i|_d|_ tj|_ |jj||jjj|_||_|jj"j%|d|_|t)|_n||_|jjj-|j*|j*j/d|j*j1d|_|jj4j7|t9d|_n||_|j:j=d|j*j?|j:|j:j7|,t9d|_ |j@jCdn||_ |j@j=d|j*j?|j@|j@j7g|_"tGdd|_$tKd d k(r|jHjCd n|jHjCd |jHj=d |jjLj?|jH|jjNjQ|jSdz dg|tU|_+n4||_+|jY|jdd|j[|j*j?|jVd|_.|jj"j_|jV|jj"j%||jjN} | jad jcd| jed| jgd|jjLjidtkdd gd|_6|jjLj?|jldi|_7tqjr|_:d|_;d|_<d |_=d|_>t|_@|jj=d|jjLj?|j|jj7dD]#} t|| t|j*| %dD]-} t|| t|jj"| /|jHjj|j|jjjj|j|j:jj|j|jjjj|j|jjjj|j|jjjj|j|jjjj|j|jjjj|j|jjjj|j|jjjj|j|jtjj|jt|jj|jd|_W|j@jj|j|jjLj|j dz|j*j|j tpjjjtpjjjtpjjjtpjjjtpjjjtpjjjg|_c|jy)a By default, this class creates an :class:`ImageItem ` to display image data and a :class:`ViewBox ` to contain the ImageItem. Parameters ---------- parent : QWidget Specifies the parent widget to which this ImageView will belong. If None, then the ImageView is created with no parent. name : str The name used to register both the internal ViewBox and the PlotItem used to display ROI data. See the *name* argument to :func:`ViewBox.__init__() `. view : ViewBox or PlotItem If specified, this will be used as the display area that contains the displayed image. Any :class:`ViewBox `, :class:`PlotItem `, or other compatible object is acceptable. Note: to display axis ticks inside the ImageView, instantiate it with a PlotItem instance as its view:: pg.ImageView(view=pg.PlotItem()) imageItem : ImageItem If specified, this object will be used to display the image. Must be an instance of ImageItem or other compatible object. levelMode : str See the *levelMode* argument to :func:`HistogramLUTItem.__init__() ` discreteTimeLine : bool Whether to snap to xvals / frame numbers when interacting with the timeline position. roi : ROI If specified, this object is used as ROI for the plot feature. Must be an instance of ROI. normRoi : ROI If specified, this object is used as ROI for the normalization feature. Must be an instance of ROI.

Parameters ---------- img : np.ndarray The image to be displayed. See :func:`ImageItem.setImage` and *notes* below. autoRange : bool Whether to scale/pan the view to fit the image. autoLevels : bool Whether to update the white/black levels to fit the image. levels : tuple (min, max) white and black level values to use. axes : dict Dictionary indicating the interpretation for each axis. This is only needed to override the default guess. Format is:: {'t':0, 'x':1, 'y':2, 'c':3}; xvals : np.ndarray 1D array of values corresponding to the first axis in a 3D image. For video, this array should contain the time of each frame. pos Change the position of the displayed image scale Change the scale of the displayed image transform Set the transform of the displayed image. This option overrides *pos* and *scale*. autoHistogramRange : bool If True, the histogram y-range is automatically scaled to fit the image data. levelMode : str If specified, this sets the user interaction mode for setting image levels. Options are 'mono', which provides a single level control for all image channels, and 'rgb' or 'rgba', which provide individual controls for each channel. Notes ----- For backward compatibility, image data is assumed to be in column-major order (column, row). However, most image data is stored in row-major order (row, column) and will need to be transposed before calling setImage():: imageview.setImage(imagedata.T) This requirement can be changed by the ``imageAxisOrder`` :ref:`global configuration option `. implements MetaArray)dtypemaxminndimshaperc36K|]}t|ywN)hasattr).0attrimgs r" z%ImageView.setImage..As?dwsD)?szYImage must be NumPy array or any object that provides compatible attributes/methods: %sN col-major)rr)rrrtxr-crrz*Can not interpret image with dimensions %szfCan not interpret axis specification %s.
