Hi Chris,
I think that Klaus formulation is better ;-) But using a function is a good choice:
function GlobalObjRect pObj return globalLoc(the topLeft of pObj),globalLoc(the botRight of pObj) end GlobalObjRect
put GlobalObjRect(the long ID of graphic "PFrame") into tRect -- ∆ export snapshot from rect tRect to file tFile as JPEG

Eric -
Thanks so much! I'm pleased I wasn't doing something daft. Your function does the trick beautifully.
Regards,
Chris

Hi Chris,
The export snapshot from rect of window windowID to file... does not appear very reliable.
So convert the rect of your object to global coordinates and use export snapshot from rect to file... instead :-)
function GlobalObjRect pRect
return item 1 of pRect + the left of this stack,item 2 of pRect + the top of this stack,item 3 of pRect + the left of this stack,item 4 of pRect + the top of this stack
end GlobalObjRect
Best regards,

Hello folks.
Can anyone shed any light on this? I'm having problems with the export syntax. I am trying to export an area of a window...
The snippet below works fine, happily creating a jpeg in the default folder, but using screen coords (which I don't want)
put the ticks & "temp.jpg" into tFile put the rect of graphic "PFrame" into pRect put the id of this wd into WinId
put prect && winId && defaultfolder && tFile
export snapshot from rect pRect to file tFile as JPEG
But if (as below) I add the window parameter to use window-relative coords, it doesn't work. Instead, I get the error: "export: no image selected, or image not open". It's as if it is suddenly ignoring the "snapshot" form of export.
put the ticks & "temp.jpg" into tFile
put the rect of graphic "PFrame" into pRect
put the id of this wd into WinId
put prect && winId && defaultfolder && tFile
export snapshot from rect pRect of window WinId to file tFile as JPEG
