使用來源,盧克。如果您在ImageMagick ++中找不到它,請回退到它的依賴項。你要找的代碼在ImageMagick的/棒/ import.c:

% ImportImageCommand() reads an image from any visible window on an X server 
% and outputs it as an image file. You can capture a single window, the 
% entire screen, or any rectangular portion of the screen. You can use the 
% display utility for redisplay, printing, editing, formatting, archiving, 
% image processing, etc. of the captured image.</dd> 

如果你不希望它到一個文件,你必須弄清楚什麼代碼正在做自己的。這看起來是代碼中唯一可以執行可訪問X11顯示的捕獲的地方,所以這是您的出發點。
