I am reading this:

https://wiki.tcl-lang.org/page/Capture+a+window+into+an+image

And I found this:

set baseImg [image create photo -format window -data $win]

Where did -format window come from?

I'm reading the manual pages of image and photo and can't find any
mention of that possibility anywhere. How did this person guess that
'window' was a valid option?

Neither can I find any clue to why the path to a widget is a valid
option for -data.

It works, but it only captures the visible part of the text widget.
I want to capture all of it. Is it possible?

It is an extension added on by the Img extension, which is mentioned at
the top of the page you cite:

David Easton 17 Mar 2003 This uses the *Img* package to capture a
screenshot of a widget hierarchy or toplevel window into a photo image.

And therefore the documentation for it is part of Img.

IIRC the Img package capture widget to image file aspect only works for
the visible on-screen parts of widgets.
