Is there a way to find the handle of a certain window and take a screenshot in Mathematica without having to call external programs? Something that connects with the API for the operating system.

    $\begingroup$ CurrentScreenImage captures full screens or a rectangle from the screen. $\endgroup$ – Jean-Pierre Sep 30 '20 at 23:45

Another way! using


to list all the windows and then copy one of them to Export!

Export["newCapture.png", copySomethingAbove, ImageResolution -> 400]

See the picture as below!

enter image description here


To control the resolution of image, we can use CreateDocument to creat a new notebook, then write some code and run. SetSelectedNotebook can be used to chose the exact window and then capture it.

nb1 = CreateDocument[Plot[Sin[x], {x, -5, 5}, PlotStyle -> Red]];
nb2 = CreateDocument[Plot[Cos[x], {x, -5, 5}, PlotStyle -> Blue]];
Export["nb1-picture.png", %, ImageResolution -> 400]
Export["nb2-picture.png", %, ImageResolution -> 400]
