Re: [Gimp-user] Unable to use 'system' command for script-fu -- Almost done
Quoting Tony Freeman: One last thing that I cannot figure out is: how do you close the dialog box that the image is sitting in? In Scheme you do it like so: (gimp-display-delete Image) I've tried the following (with variations), but it causes the python-fu to hang: pdb.gimp_display_delete(img) To the best of my knowledge, it is impossible for a script to close the display unless it was created through PDB calls (i.e., you cannot delete an image created or opened by the user). The PDB function, 'gimp-image-delete', only works with images that have been created through the PDB. Since the call to 'gimp-display-delete' will attempt to delete the image if the display you are deleting is the only one associated with the image, you end up effectively violating the conditions of 'gimp-image-delete'. ___ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user
