以编程方式创建网站图像[关闭]

Question

When I look at social bookmarking website or web master tools, they have a screenshot of a website showing.

I would like to do the same thing. How can I go about doing this? (I know they are not using iframe, but rather small thum nail size png file)

Is it possible to achieve this with javascript or do I need to use Windows or Mac OS that can take a screenshot from browser and somehow automate it?

I would like to achieve this goal with javascript or PHP, Python, Ruby. (I read somewhere that phantomjs might be able to achieve this?)

Please give teach me how I can go about with this problem.

Answer 1

You need a server side programming language that has a webkit module.

Using that you could create a widget into a virtual display and load the site in that and get a screenshot made once it's done loading.

I have done something like this using python, qt, qt webkit and pyqt but did not take a screenshot.

This might help:

Keep in mind that what you want is a bit different so just go to the point where you open the site in the widget and find a way to take the screenshot.

Also look into executing the app into a virtual display.
