Font-name-to-file-name mapping given in Fontmap files; aliases are possible, and there need not be any relation between the font name in the Fontmap and the FontName in the file. 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.
You can use the ‘ps2’ set with eps files. Note that the extended support for bit word size can be disabled by executing ‘true. It is also possible to influence the path using standard, or your own environment variables, using the custom Postscript operator getenv.
Note that UFST and Free Type cannot handle some Ghostscript fonts because they do not include a PostScript interpreter and therefore have stronger restrictions on font formats than Ghostscript itself does – in particular, Type 3 fonts. It may include records of 2 types: When upscaling, every output pixel ends up being the weighted sum of 16 input pixels, When downscaling more source pixels will contribute to the interpolated pixels.
In this case you must also use the -q switch to scanne Ghostscript from writing messages to standard output which become mixed with the intended output stream. Users will rarely need to modify these.
GSView Open Error: /invalidfileaccess in /findfont
This means you must exercise caution when using this gsvjew, and probably should not use it at all when processing a mixture of PostScript and PDF files on the same command line. Files beginning with gdev are device drivers or related code, also part of the library.
The table here lists them by name and size. Normally, pdfmark is only called for these types for PostScript files or when the output device requests it e. GSView just needs you to point it at the colour standard files on your system.
This mode also sets the. Gxview command line to invoke Ghostscript is essentially the same on all systems, although the name of the executable program itself may differ among systems. By default these are [0, 0] for the lower bound and [16 fffff, 16 fffff] for the upper bound. Avoid integer overflow on 16bit tsview when calculating width and height. To preserve the case of switches, quote them like this: See the document GS9 Color Management for details gssview this option.
Note that if geview profiles are specified for the default Device color spaces, then the system default profiles will be used. You can switch devices at any time by using the selectdevice procedure, for instance like one of these:. When upscaling, gsvkew source pixels will cover at ysview one destination pixel. For details, please consult the source file gdevx.
If this option is included in the command line, source device color values e. This may be useful on PC displays that get confused if a program attempts to write text to the console while the display is in a graphics mode. Notes on specific platforms Word size 32 or 64 bits The original PostScript language specification, while not stating a specific word sise, defines ‘typical’ limits which make it clear that it was intended to run as a bit environment. Finally, if all else fails, it will try to find a substitute for the font from among the standard 35 fonts.
The decision to halftone depends upon the output and source resolution as well as the output and source color space. They must end with semicolon.
Note that this is unrelated to the real type of the font file – the bridge will perform format conversion. If you have precompiled executables, epstool. Profiles fsview demonstrate this method of specification are also included in this folder.
However, the creation of a transformation will be faster at a setting of 0 compared to a setting of 2. The first element of the pair is the font name the name that PostScript documents use to access the font, which may differ from real name of the font which the font file defines. As noted above, when using MS Windows console command.
This can also be useful in processing large documents when using a high-level vector output device like pdfwrite that maintains significant internal state. These are all user-contributed code, so if you have questions, please contact the user identified in the file, not Artifex Software.
Makefiles This section is only for advanced developers who need to integrate Ghostscript into a larger program at build time.
By default, Ghostscript no longer searches the current directory first but provides -P switch for a degree of backward compatibility.
It may be same or different than FontPath. Unlisted font types will be rendered with the native Ghostscript font renderer.
Note that this is unrelated to the sfanner type of the font file – the bridge will perform a format conversion. Rules and definitions specific to the library on all platforms are in lib. It controls grid fitting of True Type fonts Sometimes referred to as “hinting”, but strictly speaking the latter is a feature of Type 1 fonts.
Device drivers The interface between the graphics library and device drivers is the only really well documented one in all of Ghostscript: Release with GSview 3. If you want to run UFST with resident UFST fonts only and allow Ghostscript font renderer to handle fons, which may be downloaded or embedded into documentsyou should run Ghostscript with scanmer command line arguments: This cannot be used directly in a cidfmap file because the xx notation in names is a PDF-only encoding.
For complete description of the devices distributed with Ghostscript and their options, please see the devices section of the documentation.
