| Summary | 0009423: Python Trace generator doesn't do screenshots. | ||||||||
| Description | * ParaView trunk, XP, local server. * Tools/ Python Shell/ Trace/ Start trace * Sources/ Cone. Apply. * File/ Save Screenshot. Save this somewhere. * Tools/ Python Shell/ Trace/ Stop trace * Tools/ Python Shell/ Trace/ Show trace <<Bug>> - there is no save screenshot. I tested this by saving the trace, and then executing it, and it did not save a file. <<Note - I didn't check animations, but I bet the same problem exists>> Since this is such basic functionality, it must be fixed for 3.6.2. | ||||||||

Saving a screenshot from the gui takes advantage of the Qt based view manager class. The gui lets you capture all the views together. The current pvpython api only allows you to save a single render view. The gui lets you specify a size [x, y], but from python you must resize the render window to get the desired aspect ratio and then you can pass a magnification argument to save screenshot. I could set it up so that trace only captures the save screenshot event if the user has chosen "Save only selected view" in the gui (and the selected view is a 3D render view). What do you think, Alan? |

I think that it would be OK short term, and possibly long term, to only "save only selected view". Then, the user can change the selected view, and do another "save only selected view". Thus, a user could write out each and every view serially. I think that limiting output to only 3D render is unacceptably restrictive. Users are using XY Plot View more and more, as well as 2D View. |

I think that this should wait until 3.8 when we have proper multi-view/chart-view management in the server manager. Any solution we come up with now is going to be a hack and will be thrown away in 3.8. There is enough documentation here and there that explain how you can capture a 3D window from Python. For capturing the chart windows, the users will have to wait until 3.8. |

Pat has committed a basic version to capture screenshots in trace. Deferring the extended screenshot tracing to 4.0. |
