How to take screenshot (using selection) in awesome wm via scrot?

Can you take a screenshot of a page using web-based tech?

• So I want to the ability to take a screen shot of a part of a page, without using any OS tools. So the whole thing is done with AJX, JS, HTML5, etc. Then after the capture it loads it into the page. The reason is for posting to a blog. May blogs have Bookmarklets, but they rarely snif out the right image. I want a Bookmarkelt or extention that allows me to post to a blog, and while doing that I can click a "capture an image" button where I can the drag a frame around the page and click to take the shot. Similar to OS X. Then it would capture the image and put it into my post. This would be instead of screenshoting with the OS's tool, saving it to the desktop, opening it, resizing, re-saving it, the uploading it when posting. Make sense?

• Answer:

  You might be able do this with JavaScript in an extension, where the screenshot would be easy. I'll base this off my knowledge of Chrome Extensions: http://code.google.com/chrome/extensions/index.html Starting with a few assumptions: I've got a script running in my extension's background when I prompt the extension, I'm going to capture a tab with captureVisibleTab() It returns to me a dataURL maybe it will provide me with editing and image manipulation features ( woohoo HTML5 canvas! ), eventually converting back to the dataURL format I need I can use the dataURL to set as the src attribute on an img element A couple questions I need help with: are there sites that allow you to simply give a src attribute to load an image? It would require some level of text filtering/ server processing. how vulnerable to things like cross-site scripting could this be? and could you filter the text to eliminate any vulnerabilities? Another way around allowing the user to enter the img src, would be for the blog service to provide the extension, and sending the dataURL straight to their servers from your extension without allowing you to edit any text. I hope this helps answer your question, as I took the liberty of exploring a bit with the answer. Let's get some good edits in here!
