Create screenshot of webpage

[tomrei]

Hello everyone!

I'm looking for the possibility to take a screenshot of a webpage by
using Cappuccino or Javascript - has anybody got an idea how to do
this?
I know that there a serval online tools, cocoa apps or command line
tools for this task - but it would be great if it can be done without
them.

Thanks for your help!

The answer is no. Cappuccino is pure HTML / JavaScript / CSS. Anything
these technologies can't do Cappuccino can't do.

Hi:

There's no "browser native" way of doing this. I think the only way I can imagine to do this is to use an on line preview service like snap.com. However, you'd have to be able to produce a URL that can open your app to the desired state, and that could be a big challenge (hint: you'd have to use URL arguments).

Hope this helps, 

John

You might be able to use the Canvas tag on firefox. For an extension,
you can use context.drawWindow You can then use canvas.toDataUrl

Unfortunately context.drawWindow is not allowed in normal HTML pages.

"This feature is only available for code running with Chrome
privileges. It is not allowed in normal HTML pages."

See the given URL, there you can also find the reason why this will
not be possible any time soon.
