See the section on Security for more information. Please refer to VectorDevices.
It also assumes that carriage return-newline is needed, and not just carriage return. Duplex printing If the Windows printer supports the duplex printing feature, then it will also be available through the mswinpr2 device.
Writing to stdout, pipes or other similar stream is not supported. Documentation for some older, superceded devices has been moved ghostsctipt another document. Any device author interested in trying these options should contact Artifex for more information. Please note that JPEG is a compression method specifically intended for atialiasing images such as photographs, not for graphics, and it is therefore quite unsuitable for the vast majority of page images produced with PostScript.
The PNM portable network map family of formats are very simple uncompressed image formats commonly used on unix-like systems. Values of 0 to 2 work as expected, but values 3 and 4 while accepted for compatibility will behave as for 2. The following example shows how to print on both faces of the paper using the long side of the paper as the reference: The tiffsep device will automatically recognize spot colors.
The spot color numbers are assigned in the same order as the names are printed to stderr see below. The pngpng16 and pngmono devices respectively provide antiapiasing color, 4-bit color hgostscript black-and-white for special needs.
We have been warned by the people supporting the GIMP program that they reserve the right to change the XCF format at anytime and thus these devices may become invalid.
Bug – Anti-aliasing does not work when reading a PDF
Options specific to particular file formats are described in their respective sections below. Since this file is created based upon having color planes for ghostscrjpt colorant, the file will correctly represent the appearance of overprinting with spot colors. The background is transparent unless it has been explicitly filled.
A known issue with this driver is poor support for margins and page size. As of the 0. Text not antialiased if a transparent object is behind.

To display an array of data, see image. Here is an example of such a setup file: Sign up using Facebook. This option sets the resolution of antialiasin output file in dots per inch. As the user inteface changed a bit, some of your tools that were using pstoimg may not work any more.
It supports full quality color and transparency, offers excellent lossless compression of the image data, and is widely supported. Valid values are 12and 4. Antialiasing is enabled separately for text and graphics content.
Details of Ghostscript Output Devices
If the file name specified via the OutputFile parameter ends with the suffix ‘. It is currently the latter. Merge the requests above antialiaasing the defaults. This option may not be available due to missing capabilities of external programs.
Supported options device properties Several extra options exist which cannot be set through the command-line, but only by executing the appropriate PostScript setup code. Type “png” uses a palette of colours and could give a more compact representation.
Display Devices Ghostscript is often used for screen display of postscript and pdf documents. Duplex printing If the Windows printer supports the duplex printing feature, then it will also be available through the mswinpr2 device.
Centimeters and millimeters ISO standard paper sizes such as A4 and Angialiasing are commonly represented in the SI units of centimeters and millimeters.
The recognized parameters are the following: PS2 writer The ps2write device outputs postscript language level 2. In this mode, the color model becomes “DeviceN” rather than “DeviceCMYK”, the number of components goes to six, and the color model is considered to be the yellow, cyan, cyan, magenta, 0, black tuple. The pointsize to be used for text: This is used by the Windows clients to set the antialiasinb device resolution to the Windows display logical resolution.
Generic Ghostscript options that antialiqsing particularly relevant for IJS are summarized below: Anyway, this method is mainly for vectorial elements that gohstscript be rasterized at a higher density and then get downsized and the downsizing does some sort of antialiasing.
Look at the display on the printer itself if a “Printer problem with unknown reason” is reported. Raw ‘bit’ devices There are a collection of ‘bit’ devices that don’t do any special formatting but output ‘raw’ binary data for the page images. This site features the following types: These suppress interactive prompts and enable some security checks on the file to be ghostscri;t.
Now the title and question 1 are unrelated to LaTeX and question two is answered in the “duplicate question”. It is supported by the pcxmono pcxgray pcx16 pcx pcx24b pcxcmyk series of devices.
It is the default device on the command line client on such systems, and is used more creatively by the gv client application. Comment 7 Manuel Morales Comment 3 Ray Johnston Please see the PNG website for a complete description of the format.
