>Summary: "Screenshot saved" text captured in next shot

Initial Comment:
If you grab one screenshot, then grab another too quickly (before 
"Screenshot saved: tvtime-...." disappears), the next screenshot will 
grab the text along with the image.  I can understand being able to grab 
certain things (like closed captions, time, etc.), but it seems kind of 
pointless to grab the text displayed from the previous screenshot.  Maybe add a 
flag or something to whatever is displayed on the screen indicating whether or 
not it should be saved during a screen grab (if it's possible to separate once 
it's on the screen, anyways).

I attached a screenshot, cause it's fun.  Thanks!

We still have no 'user-friendly' screenshot function, but I
am not going to put this on the 1.0 plan unless someone
offers to do the work.

i rather agree with the assertion that there should be two
kinds of screenshots; those that replicate what the user
saw, and those that capture only the image portion of the
stream. since i have to hit 's' repeatedly to make sure i
get the right shots, they frequently have the annoying OSD
in them.

I agree with all of vektor's comment on this, but I don't
think there should be any special treatment of the OSD.

A screenshot is just that -- a screenshot. You want to be
able to take screenshots of the GUI, and it would be silly
to put in extra code just to hide the "Screenshot taken" bit.

If your job is a TV action photographer :-) , what you want
is probably another, seperate, image capture command which
captures an image off the TV signal with no OSD on it, and
writes *that* to a file.

You didn't attach anything. ;-)

The screenshot function currently outputs the image of the
last frame we rendered.  To render a new frame just for the
screenshot output would be too slow, in my opinion.  Having
the OSD text suddenly disappear when you take a screenshot
would also be pretty silly: it would look like a bug.  The
real argument though is that the screenshot feature is for
debugging the rendered output more than anything else...

I do think that we're going to need to have some sort of
user-friendly screenshot output.  Specifically it would need:
1. To respect the overscan settings, don't show anything in
the screenshot that the user could not see.
2. Scale it up as required to meet the correct aspect ratio.
3. Do your OSD suggestion, likely by showing no OSD at all
in the screenshot?
4. Use png compression (?).

Thoughts?
