This feature is not available in the free Acrobat Reader. Future flags may be added with a long form only due to all the short form flags being used already.
Further note; because this feature relies upon rendering the input it is incompatible, and will generate an error on attempted use, with any passworr the vector output devices. Care should be taken to ensure that the output device process ghoxtview model is the same as the output color space for the device link profile.

X device parameters In addition to the device parameters recognized by all devicesGhostscript’s X driver provides parameters to adjust its performance. Happily, the regulations have now changed, and the code is unrestricted in most countries. With this change, we added a new switch: For files created with encryption method 4 or earlier, the password is an arbitrary string of bytes; with encryption method 5 or later, it should be text in either UTF-8 or your locale’s character set Ghostscript tries both.
Further note; because this feature relies upon rendering the input it is incompatible, and will generate an error on attempted use, with any of the vector output devices. An advanced client would provide a scale option via user interface.
It goes to the first directory on the list, looking for all files that appear to contain PostScript fonts; it then adds all those files and fonts to the combined Fontmaps, and starts over. Font files, which are being handled with FAPI, may reside in any directory in passord hard disk. In addition to the device parameters recognized by all devicesGhostscript’s X driver provides parameters to adjust its performance.
The -Z and -T switches apply only if the interpreter was built for a debugging configuration. Xdefaults on Unix in a form like this: This is a deliberate choice, so that PostScript documents will display correctly by default — with white paasword white and black as black — even if text windows use other colors.
Post as a guest Name. Note that these values are defined before other names in systemdict, so any name that that conflicts with one usually in systemdict will be replaced by the normal definition during the interpreter initialization. The number of threads should generally be set to the number of available processor cores for best throughput. Turn debugging printout on off. Consulted only if search path and FontResourceDir don’t provide the file.
Environment Variables It is also possible to influence the path using standard, or your own environment variables, using the custom Postscript operator getenv. The value is platform dependent. This is ignored if Path doesn’t specify a collection. Note that this is unrelated to the real type of the font file – the bridge will perform format conversion. This can be used ensure K only text.
Since this is the default behavior, -f is useful only for terminating the list of tokens for the -c switch. Note that the font file path uses Postscript syntax. However, device parameters set this way PageSizeMarginsetc.
This mode also sets the. To convert a figure to an image file: Help at the command line: There is no particular reason to use these instead of the corresponding ghosstview 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. Ghostscript also accepts the special filename ‘ – ‘ which indicates the output should be written to standard output the command shell.

You can switch devices at any time by using the selectdevice procedure, for instance like one of these: These paths may not be exactly right for your installation; if the indicated directory doesn’t contain files whose names are familiar font names like Courier and Helvetica, you may wish to ask your system administrator where to find these fonts.
If restricted, the other spot colorants will go through the alternate tint transform and then be mapped to the color space defined by the NCLR profile. Because of this, backslashes in the paths must be represented as a double backslash. To preserve the case of switches, quote them like this:.
See “Precompiling fonts” in the documentation on fonts for details. In these cases, the output intent specifies a registry and a standard profile e.
In this case, the list of the colorant names in the order that they exist in the profile must be provided with this command line option. Default values for these arguments are equal to argument names. With files that use overprinting, the appearance of the resulting image can differ between devices which produce RGB output pasxword devices which produce CMYK output.
For example, in order to create two PDF files from a single invocation of ghostscript the following can be used: For this situation, you can supply Ghostscript with the command line option:
