< There are many times you might want to export the contents of a card to a JPG or PNG file, and MetaCard/Revolution's built in export snapshot command takes a literal screenshot, so things like palettes and toolbars can get in the way of getting a clean image of the card.

import snapshot from rect the rect of window < windowname >
Well, the comment was condemning "export snapshot", not "import
snapshot"; import snapshot suffers many of the same problems, though as
the TD states: "if the window is partly overlapped by another window,
whatever is visible on the screen within that rectangle is placed in the
snapshot". Basically, it literally takes a screen capture, whereas the
tip at
http://www.sonsothunder.com/devres/revolution/revolution.htm? _imag007.ht
m is not doing a screen capture; it is reading directly from the
window's image buffer to create the export.
Just a clarification,
:^) in the TD is stated:
export snapshot [from rect[angle] rectangle [of window windowID]] \
to {file filePath |container} [as format] [with mask maskFile]and this works:
on mouseup
export snapshot from rect the rect of this stack to txCurrentCardImage as PNG
put txCurrentCardImage into fld "thumbnail"
end mouseup
