A few experiments later.... and it seems the message is that the docs
are wrong - firstly there seems no point using "of object" form,
instead use only of "window windowID". Also the docs are wrong in that
you don't need the stack to be topmost - so the following script seems
to work fine at the moment:
getprop object_SnapShot [imageType]
-- see also "image_GetSnapShot"
put the long id of the target into targetObject
put the stack_Object of targetObject into stackObject
-- toplevel stackObject
put the windowid of stackObject into wID
put the rect of targetObject into localRect
switch imageType
case "GIF"
export snapshot from rect localRect of window wID to
someImage as GIF
break
case "JPG"
export snapshot from rect localRect of window wID to
someImage as JPEG
break
case "JPEG"
export snapshot from rect localRect of window wID to
someImage as JPEG
break
default
export snapshot from rect localRect of window wID to
someImage as PNG
end switch
return someImage
end object_SnapShot
I've updated the docs here (feel free to comment on / edit the wiki
page) - http://handlers.rev-co.de/wiki/export%2Bsnapshot.
