See the AdjustWidth option documentation below for important information about these devices. Multi-strip files reduce the memory requirement on the reader, since readers need only store and process one strip at a time. The TIFF 6. If the value of the MaxStripSize parameter is smaller than a single image row, then no error will be generated, and the TIFF file will be generated correctly using one row per strip. Note that smaller strip sizes increase the size of the file by increasing the size of the StripOffsets and StripByteCounts tables, and by reducing the effectiveness of the compression which must start over for each strip.
If the value of MaxStripSize is 0, then the entire image will be a single strip. Since v. According to the TIFF 6. Unfortunately, due the unpredictable size of compressed output, we cannot automate the selection of BigTIFF, using it only when the output file grows large enough to warrant it. For the tiffsep device, it changes the compression scheme of the separation files and composite cmyk file which is lzw by default.
It defaults to g4 for the tiffsep1 device. This behavior is the default for all the fax based devices i. When using this option with tiffscaled it is the downsampled size that triggers the adjustment. This is useful for output devices that are high resolution, but that have trouble rendering isolated pixels. While this parameter will accept values from 0 to 4, not all are fully implemented. The mechanism by which MinFeatureSize is implemented for tiffscaled is different, in that it is done as part of the error diffusion.
Values of 0 to 2 work as expected, but values 3 and 4 while accepted for compatibility will behave as for 2. This is useful when the file uses overprint to separately paint to some subset of the C, M, Y, and K colorants, but the final CMYK is to be color corrected for printing or display.
The values are bits ranging from 0 to This code is disabled by default; see the note below as to why. Trapping is a process whereby the output is adjusted to minimise the visual impact of offsets between each printed plane. Typically this involves slightly extending abutting regions that are rendered in different inks. The intent of this is to avoid the unsightly gaps that might be otherwise be revealed in the final printout if the different color plates do not exactly line up.
This trapping is controlled by 3 device parameters. The final control is to inform the trapping process in what order inks should be processed, from darkest to lightest. This is the default. Until we can convince ourselves that our trapping code is not covered by any of these patents, the functionality is disabled by default.
Any patents that do cover the code are invalid in your jurisdiction. That you have appropriate patent licenses for any patents that do apply. The later case is described here. The fax devices are faxg3, faxg32d and faxg4. It is supported by the devices bmpmono bmpgray bmpsep1 bmpsep8 bmp16 bmp bmp16m bmp32b. It has some support for image compression and alternate color spaces, and so can be a useful way to output CMYK.
It is supported by the pcxmono pcxgray pcx16 pcx pcx24b pcxcmyk series of devices. It is supported by the psdcmyk and psdrgb devices. Of special interest with the psdcmyk device is that it supports spot colors. See the comments under the tiffsep and tiffsep1 device about the maximum number of spot colors supported by Ghostscript The psdcmykog device produces PSD files with 6 components: Cyan, Magenta, Yellow, blacK, Orange, and Green.
The psdcmyk device supports the same trapping options as tiffsep but see this note. An attempt to output multiple pages to a single PSD file i. For PCLm there are some additional rules regarding headers, extra content and the order in which the content is written in the PDF file. There are four devices named pdfimage8, pdfimage24, pdfimage32 and PCLm. Finally, the PCLm device supports the -dStripHeight switch to set the vertical height of the strips of image content, as required by the specification.
These allow Ghostscript to preserve as much as possible the drawing elements of the input file maintaining flexibility, resolution independence, and editability. High-level devices The pdfwrite device outputs PDF.
PS2 writer The ps2write device outputs postscript language level 2. It is recommnded that this device is used for PostScript output. There is no longer any support for creating PostScript level 1 output. EPS writer The eps2write device outputs encapsulated postscript. Text output The txtwrite device will output the text contained in the original document as Unicode.
Please refer to VectorDevices. Display Devices Ghostscript is often used for screen display of postscript and pdf documents. This section describes the various display-oriented devices that are available in Ghostscript. It is the default device on the command line client on such systems, and is used more creatively by the gv client application. The available devices are: This is the default device, handling display on X11R6. On Mac OS X as of Options The display device has several user settable options.
This is used by the Windows clients to set the display device resolution to the Windows display logical resolution. This can be overriden by the command line option -rDPI. When using the separation color space, the following options may be set using setpagedevice, as described in the PostScript Language Reference: SeparationColorNames An array giving the names of the spot colors SeparationOrder An array giving the names and order of the colorants to be output.
IJS - Inkjet and other raster devices IJS is a relatively new initiative to improve the quality and ease of use of inkjet printing with Ghostscript. Using IJS, you can add new drivers, or upgrade existing ones, without recompiling Ghostscript. All driver authors are encouraged to adapt their drivers for IJS, and if there is an IJS driver available for your printer, it should be your first choice. Ghostscript will spawn a new process for this driver, and communicate with it using the IJS protocol.
See the section on Security for more information. In general, consult the documentation for the driver to find the appropriate settings.
If it is necessary to send a value containing a comma or backslash, it can be escaped with a backslash. If not set, Ghostscript simply passes the filename set in OutputFile to the server. The default value of 8 should be appropriate for most work. Generic Ghostscript options that are particularly relevant for IJS are summarized below: -rnumber -rnumber1xnumber2 Sets the resolution, in dpi. If the resolution is not specified, Ghostscript queries the IJS server to determine the preferred resolution.
When the resolution is specified, it overrides the value if any preferred by the IJS server. Tumble controls the orientation. When Tumble is false, the pages are oriented suitably at the left or right. When Tumble is true, the pages are oriented suitably for binding at the top or bottom.
Others may need some makefile tweaking. Last, make sure that ijs. It should be present right after the include of icclib. IJS is not inherently platform-specific. Rinkj - Resplendent inkjet driver The Rinkj driver is an experimental new driver, capable of driving some Epson printers at a very high level of quality. It is not currently recommended for the faint of heart.
In addition, we rely heavily on an ICC profile for mapping document colors to actual device colors. For 6- and 7-color devices, the target color space for the output profile is currently a 4-component space.
The conversion from this into the 6- or 7-color space the "ink split" is done by lookup tables in the setup file. Setup files are in a simple "Key: value" text format.
Usually, this should match the Ghostscript resolution set with the -r switch. Otherwise, the page image will be scaled.
Currently, the choices are 1 for one-bit dither, and 2, for a 2-bit variable dot dither. Valid values are 1, 2, and 4. For best results, choose a value near the x resolution divided by the y resolution.
For example, if resolution is x, aspect should be 2. The plane is one of "CcMmYKk". The lookup table data follows. The line immediately following AddLut is the number of data points. Then, for each data point is a line consisting of two space-separated floats - the output value and the input value. If more than one LUT is specified for a single plane, they are applied in sequence.
It is configured for the , but can be adapted to the just by changing the "Model" line. A known issue with this driver is poor support for margins and page size. In some cases, this will cause an additional page to be ejected at the end of a job. This version of Ghostscript includes the patch from version 0.

Merr In general, consult the documentation for the driver to find the appropriate settings. If you antialiaisng to measure larger pages than this, you must reset both the resolution and the page size in pixels, e. You select it in the usual way: There are five color TIFF drivers that produce uncompressed output: These numbers start with 0 for the first spot color. The default is There is a special inkcov device that just prints the ink coverage of each page. Duplex printing If the Windows printer supports the duplex printing feature, ghostscriipt it will also be available through the mswinpr2 device. Sign up using Facebook. The bitmap type extension is appended automatically if file does not contain a dot.
GHOSTSCRIPT ANTIALIASING PDF
Also, since some devices write output files when opened, there may be an extra blank page written pdfwrite, ps2write, eps2write, pxlmono, pxlcolor, As noted above, when using MS Windows console command. This is intended to be a quick way to invoke ghostscript to convert one or more input files. For instance, to convert somefile. Individual documents can and often do specify a paper size, which takes precedence over the default size.
Akihn The spotcmyk device was also ghostsctipt to provide example code for a device which supports spot colors. The spotcmyk device produces a binary data file similar to the bitcmyk device for the CMYK data. The mswinpr2 device supports a limited number of command-line parameters e. The pngalpha device is bit RGBA color with transparency indicating pixel coverage. Tumble controls the orientation. The pngmonod device is also a black-and-white device, but the output is formed from an internal 8 bit grayscale rendering which is then error diffused and converted down to 1bpp.
Fegor Bug — Anti-aliasing does not work when reading a PDF A typical command antiaoiasing invocation is: You will need to add the following line to your makefile: The equivalent CMYK color for each spot color is determined using the alternate tint transform function specified in the Separation and DeviceN color spaces. Otherwise ask for the page size by specifying only its dimensions. Still this option is there to enable tuning by hand, although it is deprecated. We recommend moving to the ijs device for all such printing.
