如何在linux中快照 - 以编程方式C ++ [英] How to take snapshot in linux - programmatically C++

问题描述

我目前参与一个项目，需要我反复拍摄屏幕的快照。我使用qt的grabScreen函数做同样的。
每次程序拍摄快照时屏幕会冻结半秒，导致计算机似乎很慢：（

I am currently involved in a project which requires me to repeatedly take snapshots of the screen. I am using qt's grabScreen function to do the same. The screen freezes for half a second every time the program takes a snapshot causing the computer to seem to be very slow :(

任何人都可以建议我更好这样做的方法？

Can anybody suggest me a better method of doing this ?

推荐答案

你可以看看 ksnapshot 这是基于Qt的KDE应用程序，它的SVN存档是这里。

You could look at the source of, say, ksnapshot which is the Qt-based KDE app doing this. Its SVN archive is here.
