Screengrab is a very simple extension. The biggest thing that people don’t do is notice the addition to their right-click context menu (which is why there’s now an icon too).

If you’re stuck and need a question answered, try emailing me at: andy at screengrab dot org.

Or you could comment on this page. I’ll use it to keep track of bugs and issues. If something is wrong, stupid or unclear, I’ll try to clarify here.

So without further ado, let’s begin…

Screengrab doesn’t ask me where to save the file.

Update: WAIT A MINUTE!! Are you people using Firefox 1.5? That’s not supported! It shouldn’t even install. Wait! The stupid config says it is. OH MY GOD! I’ve been tearing my hair out over that!? Use Firefox 2.

There seems to be a bug in the canvas implementation. I can’t replicate it (yet) but I’m trying to figure it out. My life is kinda busy, but I’m doing what I can. In the meantime you can fall-back to Java-mode to fix it.

Go: Tools->Addons->Screengrab->Options and select Java instead of Canvas.

This won’t help with the clipboard stuff though. Currently clipboard NEEDS canvas.

It doesn’t work

See: Screengrab doesn’t ask me where to save the file.

I don’t like the Context-menu / Status bar icon. How do I get rid of them?

You can’t yet. The option will appear in the next version of Screengrab.

Can I call it from the command line?

Not yet. I’m working on it.

Screengrab! didn’t save the whole page! I want my money back!

Screengrab isn’t perfect. It’s actually harder than you think to get accurate dimensions for all pages, sometimes the stuff that DOM reports is just plain wrong. If you’ve got a page that doesn’t work, send me the URL and I’ll try to figure out why.

I like the selection tool, but can you make it scroll when it hits the border of the page?

I’ll try…

Jpeg image quality sucks!

It sure does. I just figured out the params required to make it better. Configurable quality in the next release.

Copy and paste produces gibberish in some programs

I think this is to do with the cleverness of the receiving program. I only tested this by pasting into Preview on my Mac. The way I do copy-paste is a hack using a hidden image and base-64 encoded image data as a src url. The copy is fundamentally done by Firefox though so I’m going to say this bug is theirs. Having said that, I’ll try and figure out a better way to do this.
