How to create a screenshot of the currently active window ?

[aaron_caffrey]

Hello everyone,

In imagemagick there is a command ( import -frame -window ) where I can specify which is the active window and create a screenshot, but I am unable to find any article about that for magick++.

Can you help me ?

[magick]

Use the x: coder with a X window ID. For example, xwininfo reports a windows ID of 0x240003d. Use read("x: 0x240003d") in Magick++. To test, try

• convert x:0x240003d x:

How can I create a screenshot of active window in windows 7 ? I can't find a "x window Id", xwininfo is just for Linux.

Under Windows you need should use the following file name: 'screenshot:' (This requires the latest version of ImageMagick). And if your computer has multiple monitors you can specify an index 'screenshot:[1]'.

Hi all

I am also trying to use `imagemagick` to capture the primary screen on my multi-monitor setup in _Windows10_

Did anybody try the

`convert 'screenshot:[1]` option that @dlemstra mentioned above?

Yes, on Windows 8.1. It works. For my laptop, with a second screen, to capture them both:

Code: Select all

convert screenshot:[0] main.png

Code: Select all

convert screenshot:[1] second.png
