Time for action – transferring imageData

By setting the chosen image to be the same width and height as the group that holds the puzzle pieces (that's where the 900 and 662 numbers came from), it becomes possible to transfer the matching rectangle of data from the full image to the puzzle piece in question.

1. Open the card script again. Add the makepuzzle handler:

   on makepuzzle
      resetpuzzle
      put the number of images in group "pieces" into imagecount
      repeat with a = 1 to imagecount
         makepiece the short name of image a of group "pieces"
      end repeat
   end makepuzzle

2. The makepuzzle handler will go through each of the puzzle pieces and call another handler to do the transfer of data for that piece. Here is the makepiece handler:

   on makepiece piecename
      put the width of image piecename into piecewidth
      put the height of image piecename into pieceheight
      put empty into tempimage
      put the left of image piecename - the left of group "pieces"into dx
      put the top of image piecename...
