Description:
 def takeScreenshot(self, times=None, prefix="./screenshot", resetCounter=False, archive=None,mode="snapshot"):
 """ Take one or more screenshots of the widget and save the images to a file. The images can be used to create a video. This function cannot be called multiple times within one cell. Note: this is a new feature and might not work on all systems. It was tested on python 2.7.10 and 3.5.2 on MacOSX. Parameters times : (float, list), optional If this argument is not given a screenshot of the widget will be made as it is (without integrating the simulation). If a float is given, then the simulation will be integrated to that time and then a screenshot will be taken. If a list of floats is given, the simulation will be integrated to each time specified in the array. A separate screenshot for each time will be saved. prefix : (str), optional This string will be part of the output filename for each image. Follow by a five digit integer and the suffix .png. By default the prefix is './screenshot' which outputs images in the current Note that the prefix can include a directory. resetCounter : (bool), optional Resets the output counter to 0. archive : (rebound.SimulationArchive), optional Use a REBOUND SimulationArchive. Thus, instead of integratating the Simulation from the current time, it will use the SimulationArchive to load a snapshot. See examples for usage. mode : (string), optional Mode to use when querying the SimulationArchive. See SimulationArchive documentation for details. By default the value is "snapshot". Examples -------- First, create a simulation and widget. All of the following can go in one cell. The widget should show up. To take a screenshot, simply call A new file with the name screenshot00000.png will appear in the current directory. Note that the takeScreenshot command needs to be in a separate cell, i.e. after you see the widget. You can pass an array of times to the function. This allows you to take multiple screenshots, for example to create a movie, """
