6.2.2. itom.figure.liveImage

figure.liveImage(cam, areaIndex=currentAreaIndex, className='', properties={}) → plotItem

Shows a camera live image in the current or given area of this figure.

If no className is given, the type of the plot is chosen depending on the type and the size of the object. The defaults for several plot classes can be adjusted in the property dialog of itom.

You can also set a class name of your preferred plot plugin (see also property dialog of itom). If your preferred plot is not able to display the given object, a warning is returned and the default plot type is used again. For dataObjects, it is also possible to simply set className to 1D or 2D in order to choose the default plot type depending on these aliases.

Every plot has several properties that can be configured in the Qt Designer (if the plot is embedded in a GUI), or by the property toolbox in the plot itself or by using the info() method of the corresponding itom.uiItem instance.

Use the properties argument to pass a dictionary with properties you want to set to certain values.

Parameters:

camdataIO

Camera grabber device from which images are acquired.

areaIndexint, optional

Area index where the plot canvas should be created (if subplots exists). The default areaIndex is the current subplot area, hence, 0 if only one plot area exists in the figure.

classNamestr, optional

class name of desired plot (if not indicated or if the className cannot be found, the default plot will be used (see application settings)

propertiesdict, optional

Optional dictionary of properties that will be directly applied to the plot widget.

Returns:

plotHandleplotItem

Handle of the subplot. This handle is used to control the properties of the plot, connect signals to it or call slots of the plot.
