use Python to call ImageMagick's “import”

问题

I want to capture a screenshot of an application's window from a Python script using ImageMagick, as I would with ImageMagick's "import" command from a shell. An API call or a system call from Python (as in "subprocess.Popen(["import"...") will suffice, but I don't want to create a file on the hard drive. My OS is Linux.

回答1:

Execute the command:

import png:-

This will cause import to output to stdout.

You can also change png to one of the type tags shown here.
