export jpeg frustration

[Eric Chatonet]

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,
