because a *screen* capture do what is said, capture the screen. How

Now, I know nothing about how these things work but it seems to me that
a screengrab program must look for some marker which "tells" it where
the 'screen' to capture begins and where it ends. Right? Or put another
way, the program looks for the marker showing the beginning of a "file"
(SOF) and the end of file (EOF) and captures what is between the SOF and
To me, something tells Spectacle to consider the EOF to be the last
pixel of the displayed screen, while Screengrab! actually looks for the
EOF of, say, an article when one selects the 'Complete Page' option.
No, Spectacle does not look for the end. It only sees what is displayed in
the display, nothing more. It simply reads the graphic card memory, or the
X representation of the same.
I am trying hard to understand this, but surely the complete "page" is stored
in the gpu memory or the X representation of it, as you put it, because the
invisible part, which is not visible on the screen, is instantly displayed
when you either hit the 'down' key or use the scroll wheel on the mouse?
The application may have the invisible part of the page prepared or even
rendered, but the image memory doesn't know anything about that.
What is beyond the display is only known to each
does not have permission to read each application own memory,
Then give it "permission" to do so.
Can't. Huge security hole. Plus spectacle would have to be programmed to
know internals of every application that paints the screen. There would be
then a list of supported apps and not. And then supported versions and
Huge programming job. Hundreds of people needed, for ages. Any
modification in any of the supported applications, and spectacle would
have to be re-compiled and possibly re-designed.
even if it
knew how to interpret it.
And to me, the description of what each of the
"Capture Mode" (here:
) means may just as well been been written in Aramaic :-).
The Full Screen (All Monitors)
The Current Screen
The Active Window
The Window Under Cursor
The Rectangular Region option allows you to select a rectangular region of
your desktop with your mouse
They seem pretty obvious to me :-? I don't even need to read the
OK, then please tell me what each is supposed to mean -- apart from the "The
Current Screen" and "The Rectangular Region" which even I can understand
The current screen is exactly and only what is displayed by the
current monitor. Plain simple. I don't understand what you don't
If there are more monitors, then the Full Screen is all of them, joined.
As if a single huge monitor of the appropriate shape was used instead.
Active Window, the Thunderbird window frame where you are reading this.
You click on another window, that becomes the active window. If you move
the mouse to another window but don't click on it, that is the window
