Is there some tool within Opera, or possibly an add-on, which will let me take a screenshot of an entire web page? I usually use Screengrab to do this with Firefox, but in this situation I want a screenshot of the page as Opera renders it (because I want to show the page as rendered with HTML5 form controls like date and time).
I am currently using Opera 10.60 x86_64 on Fedora 12, so solutions that work in browser would be preferable rather than external programs.
I purchased ashampoo Snap 3 for this very reason.
After purchasing I did become aware of the following:
There maybe more out there that are paid and/or free but this small list should get you started. I am sorry none of these integrate with Opera like you require but you may have to just adjust your workflow for what you require.
Update: I jumped to a conclusion about you O/S and for that I am sorry! List updated with more specific to your needs and O/S
Edit: There is now an extension that allows taking a screenshot of an entire webpage in Opera: Screenshoter (requires Opera 12.10+).
With the current stable build, there is no function or extension API that allows this. But there are now Opera developmental builds which contain a screenshot API, so we may see a screenshot extension or native function for Opera in the near future:
I know you said you prefer an in browser feature, but I don't use Opera so I can only suggest external methods.
If you use windows 7 the snipping tool (which comes free with every version of 7 I believe, located under accessories) can be used to drag and select any part of the screen (in your case just the browser window) and later edited in it's simple editing panel. It's a very tiny program and takes about 2 minutes to learn to use, literally.
Or you could always take a screen shot by hitting the print screen button on your keyboard and croup out everything other than the browser window in a graphics editing program like Photoshop, Fireworks or even the primitive MS Paint, such a crop job takes no graphics editing experience as it's just a matter of selecting the crop tool, dragging it over the area in the image that you want to keep and double clicking the mouse and saving the result.
Another external suggestion is Jing (http://jingproject.com/), a free capture tool for Windows and Mac OS X. It will grab 'natural' areas in windows such as the whole window, the tabs, or the client area. It can also be used to drag to highlight a specific area and capture just it. It can also capture movies with audio.
