zoom image effect?

[Eric Chatonet]

Hi Nicolas,

On-the-Fly and not tested but should do the job :-)

function MayIZoomOut pImage
  if the left of img pImage <= 0 then return false
  if the right of img pImage >= the width of this cd then return false
  if the top of img pImage <= 0 then return false
  if the bottom of img pImage >= the height of this cd then return false
  return true
end MayIZoomOut

And inside your repeat loop:
if MayIZoomOut("My image") then...

Best Regards from Paris,

Eric Chatonet.
