Calling
gp:load-image
on a
gp:image
object now associates the image with the specified port (if the image was not already associated). This means that the image is not destroyed until the port is destroyed or
gp:free-image
is called with that port and image.
In LispWorks 5.1 and earlier calling
gp:load-image
on a
gp:image
can create a situation in which the image is destroyed while it is used by the port. The change prevents this.
