The Edit Slide dialog allows you to edit a raw slide line. This means that what you see in the Edit Slide dialog is what the dvd-slideshow program will see. Since the object of gdvdslides is to protect you from that, you must be very careful when making changes to a slide line using this dialog.
Edit Slide Dialog
The slides being edited follow the layout set forth in the documentation for the dvd-slideshow program. Removing colons from the line can cause the line to fail during compilation, unless you know what you are doing.
