Remove security limitations from PDF documents using ghostscript
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.
There is, therefore, a chance that glyphs may be wrong, or missing in the output when this fallback is used. By convention, it is often, but not exclusively, used to aid the positioning of content on the usually larger, in these cases media. CID font resources must first be combined with a CMap resource, which defines specific codes for glyphs, before it can be used as a font.
The trailing semicolon and the space before it are both required. The Ghostscript distribution ghostfiew some Unix shell scripts to use with Ghostscript in different environments. Please see the reference sections on options and devices for a more complete listing. Antialiasing is enabled separately for text and graphics content.

There is no particular reason to use these instead of the corresponding fonts in the Ghostscript distribution which are of just as good qualityexcept to save about a megabyte of disk space, but the installation documentation explains how to do it on Unix.
The build system will cope with the file being removed, and the initialization code will avoid adding the internal fall back mapping if the file is missing. Note that if no profiles are specified for the default Device color spaces, then the system default profiles will be used.
Some servers do not implement tiling properly.
Used to resolve relative paths in FAPIfontmap. There are two important incompletenesses of the implementation: To use this feature: Improving performance Ghostscript attempts to find an optimum balance between speed and memory consumption, but there are some cases in which you may get a very large speedup by telling Ghostscript to use more memory. Absolute path to a directory, which contains fonts to substitute to CID fonts. This option and the old parser will be removed when the new parser proves its reliability.
It is recommeded that this is used only for simple values — use -c above for complex values such as procedures, arrays or dictionaries. This can be used to obtain perceptually pleasing images. In this case, spot colors will pass through unprocessed assuming the device supports those colorants. Secondly, there is no ‘PDFPassword’ switch for the pdfwrite device, which is why its having no effect.
