TKdoPICT will place any PICTure in the clipboard into your stack as a PICT resource, or, retrieve a PICT resource from the stack and place it in the clipboard.
It will also allow you to display a PICT in black and white directly in the HyperCard bitmap. TKdoPICT can be used to do "dragging" animations, pasting, or selected pasting of PICTs.
To apply full color to your stacks see the companion XCMD TKshowPICT.
