This feature is not available in the free Acrobat Reader. This may be useful for backward compatibility with old versions of Ghostscript and Adobe Acrobat, or for processing files with large values of UserUnit that otherwise exceed implementation limits.

With a display device this isn’t necessary as the device handles presenting the output on screen internally. Refer to the SavedPages document for details. Further note; because this feature relies upon rendering the input it is incompatible, and will generate an error on attempted use, with any gjostview the vector output devices.


This policy has, no doubt, encouraged PDF generators to be more careful. These psuedo operators are not a part of the official Postscript specification. Our new policy is to try to render broken PDF’s, and also to print a warning, so that Ghostscript is still useful as a sanity-check for invalid files. Please refer to the documentation for those applications for using Ghostscript in other contexts.
