Kgif – A Simple Shell Script to Create a Gif File from Active Window
Kgif - 一个从活动窗口创建 GIF 的简单脚本
============================================================
[Kgif][2] is a simple shell script which create a Gif file from active window. I felt this app especially designed to capture the terminal activity. I personally used, very often for that purpose.
[Kgif][2] 是一个简单的 shell 脚本，它可以从活动窗口创建一个 GIF 文件。我觉得这个程序专门是为捕获终端活动设计的。我经常用于这个。
It captures activity as a series of PNG images, then combines all together to create a animated GIF. The script taking a screenshot of the active window at 0.5s intervals. If you feel, its not matching your requirement, straight away you can modify the script as per your need.
它将活动捕获为一系列的 PNG 图片，然后组合在一起创建一个GIF 动画。脚本以 0.5s 的间隔截取活动窗口。如果你觉得这不符合你的要求，你可以根据你的需要修改脚本。
Originally it was created for capturing tty output and creating preview for github projects.
