Facing error in Script for taking Screenshots

Neil Handa

Hello everyone, I am working on a script to automate the process of taking screenshots of graphs in Hypergraph. I am using the below commands in Tcl for the same:

for {set i 0} {$i < $numOfWindows} {incr i} {     set filename "pic$picnum.jpg"     "page$cnt" SetActiveWindow $activeWindow     "page$cnt" SetActiveWindowExpanded true     sess CaptureActiveWindow jpeg $filename percent 100 100     "page$cnt" SetActiveWindowExpanded false     incr activeWindow     incr picnum }

However the issue is that sometimes, I am not getting the screenshot of the graph and instead I am getting blank / black images. I have attached pictures for reference. Any help regarding the same would be appreciated. Thanks.

EDIT:
After some changes to the code, it is working fine now. I am now using CaptureActiveScreen instead of CaptureActiveWindow.

is your graphic card driver updated?

 

Not to solve your issue, but have you heard of HWC? these are new APIs much easier to automate some post-processing activities.

You can enable the HWC console (View>>HWC Console).

It logs most of the commands into a console, that you could then copy to TCL and easily script on top of it.
