The _CLIPBOARDIMAGE function pastes an image from the clipboard into a new 32-bit image in memory.


Syntax

newImageHandle& = _CLIPBOARDIMAGE


Description

  • When the paste operation is successful, newImageHandle& will be < -1. Handle values of -1 or 0 indicate that there wasn't an image in the clipboard or that the format wasn't accepted.
  • Use _FREEIMAGE to free the memory used by newImageHandle& when it's no longer needed by your program.

        PRINT "Width :"; _WIDTH(img&)
        PRINT "Height:"; _HEIGHT(img&)
        w = _WIDTH / 2 - _WIDTH(img&) / 2
        IF w < 0 THEN w = 0
