Take a screen shot from command line in Windows

"Download imagemagick. Many command line image manipulation tools are included. import allows you to capture some or all of a screen and save the image to a file. For example, to save the entire screen as a jpeg:

import -window root screen.jpeg

If you want to use the mouse to click inside a window or select a screen region & save a a png, just use:

import box.png"

"it can be done without external tools (you just need installed .net framework ,which is installed by default on everything from vista and above) - screenCapture.bat. It is a selfcompiled C# program and you can save the output in few formats and capture only the active window or the whole screen:

screenCapture- captures the screen or the active window and saves it to a file
Usage:
screenCapture filename.format [WindowTitle]

filename - the file where the screen capture will be saved
format - Bmp,Emf,Exif,Gif,Icon,Jpeg,Png,Tiff and are supported - default is bmp
WindowTitle - instead of capturing the whole screen will capture the only a window with the given title if there's such

Examples:

call screenCapture notepad.jpg ""Notepad""
call screenCapture screen.png"

"You can try the boxcutter tool:

usage: boxcutter [OPTIONS] [OUTPUT_FILENAME]

Saves a bitmap screenshot to 'OUTPUT_FILENAME' if given. Otherwise,
screenshot is stored on clipboard by default.

-c, --coords X1,Y1,X2,Y2 capture the rectange (X1,Y1)-(X2,Y2)
-f, --fullscreen fullscreen screenshot
