Hello,
I'm looking for a lisp or .net function which will tell me which Images or PDF files have been unloaded from a drawing.
It seems easy enough to tell if a xref had been unloded with the flag 70, if an Image or PDF has been orphaned then there are no instances of the image in the drawing.
However if the Image or PDF has been unloaded then the instances are still there just not visible. So I'm finding it very difficult to tell if the Image or PDF has been unloaded. In the end I am hoping to detach the inloaded PDFs and Images.
Any help would be very much apprechiated.
Kind Regards
David
