The Alparon research group at Delft University of Technology aims to improve automated speech processing systems for information retrieval and information storing dialogues. The current focus is on dialogue management for a research project of Openbaar Vervoer Reisinformatie. The company provides information about Dutch public transport systems, ranging from local bus services to long -distance trains. They are capable of giving up-to-date travel advice from any address to any other address in the Netherlands. Last year they received over 12 million calls for information. Since we use a corpus-based approach, we analyze tons of data. Due to the size of our data we do just about everything the Unix way: We use only stdin and stdout, and we run our scripts just as sed does (Those who can't program, write C/C++ programs; those who can, try to stick with scripts as long as possible. See also the White Paper in the References). Basically, we torture our data with Perl (and its little friends like

65. How To Use Adobe PostScript Language Files Properly. Adobe postscript files contain programming to draw the image and may and usually do An Adobe postscript print file may be any legal postscript program. http://www-cdf.fnal.gov/offline/PostScript/AdobePS.html

How to use Adobe PostScript language files properly. About 90% of the Adobe PostScript problems at CDF are the result of violating one rule Illustrations should be EPS files and should be generated and tested as such! In the case where Ghostscript, gs, will display the file, but it will not display properly when using a Ghostscript managing program such as Ghostview (ghostview) or gv, is that the file has improper Document Structuring Comments (DSC; see below). The wrapper programs are dependent on there either being no DSC or that the DSC is proper. The case of no DSC results in not having a page number that works. Another major source of problems is improper copying of Adobe Postscript files between machines with very different operating systems. Most Adobe PostScript files are ASCII and should be moved as text. Adobe PDF files are binary and must be moved as such. For example, FTP and Kermit must be told which method to use. Magic bullets for addressing Adobe PostScript problems in the general case are mathematically impossible.

CS Home Index People Teaching ... Manage Unit PostScript primer PostScript is a programming language to describe graphics pages. PostScript is a stack based language. That means, that instead of writing an expression in the form you will write , meaning push 2 on a stack, push 3 on a stack, push 4 on a stack, add the top two numbers (3 and 4), and push the result back, multiply the top two numbers (2 and 12), and push the result back. Similarly, if you want to call a function, you do not write monkey(12, 13, 14) but 12 13 14 monkey Standard functions There is a rich set of built in functions to perform basic graphics operations. They are slightly cumbersome at first sight, but very powerful once you are trying to do advanced features. The most important 4 functions are: x y moveto x y lineto x y rmoveto x y rlineto The first sets the current point to (x,y) . The second function will create a line between the current point and (x,y) . The third function moves the current point by a distance (x,y) . The fourth function will create a line between the current point and the current point moved to (x,y)

It is perhaps the most versatile and loved language for printers, being used in printers world-wide. It is capable of drawing to computer screens and any kind of drawing device. PostScript is interpreted, stack based and has latent typing. It somewhat resembles the computer language FORTH. A number of programmers write PostScript programs directly for a variety of drawing applications. The NeXTSTEP Operating System, running on Intel-486 and Motorola machines, uses Display PostScript Level II to manage the display. However, PostScript programs are usually documents meant to be printed that have been generated by a program written in some compiled language. Allen B

By David Evans For people who aren't experts in the area of high-end digital imaging, the differences between and PDF (Portable Document Format) might be a bit foggy. In fact, you've likely heard people touting PDF as the replacement for PostScript. Have you ever wondered why? Let's start with a definition of what PostScript and PDF are at a very fundamental level. We'll take a quasi-technical look at both, after which the mists will vanish and all will be revealed. A matter of language First, let's look at PostScript. PostScript is a page description language - a programming language, much like those that software engineers use to build applications. In fact, you can do an experiment to prove this to yourself. In , create a new document and draw a box. Save this file, and open it in a word processor. What you'll see is a "program," written in the PostScript language, that defines the dimensions of a page and draws a box on it. In the earliest days of PostScript, drawings could be created only by manually typing in the PostScript language. Programmers would read the

HOME ABOUT US FAQS PC UPDATE ... SECURE ACCESS The magazine of the Melbourne PC User Group PostScript - For the bookshelf Major Keary PostScript derives from work done at Xerox PARC in the late 1970s and early 1980s; commercial development was taken over by Adobe Systems and now PostScript is firmly established. It is widely used for the production and transfer of documents for the print industry, and has given us the PDF format. For many computer users PostScript is a black art, the secrets of which are known to only a privileged few. PostScript is both a page description language and a programming language. PostScript files are created and stored in "pure" ASCII, which means the original 7-bit standard set out in ANSI X3.4-1968; files contain only those ninety-three characters that are represented on the keyboard: a-z, A-Z, 0-9, space, and the punctuation marks and other symbols for which there are keys. PostScript files are platform-independent and particularly robust for transmission over poor communication connections. They can also be very large files, but compress well. Creating PostScript files is easy. Just use a PostScript printer driver (you don't need a physical printer) and print-to-file from any application that provides a print function (word processor, DTP, graphics, and so on). There is plenty of software-some free-that will convert a PostScript file to PDF. Even printing on non-PostScript printers can be achieved with software emulation, such as provided by

In the jargon of the day, it is a page description language. It was introduced by Adobe in 1985 and first (to my knowledge) appeared in the Apple LaserWriter. The main purpose of PostScript was to provide a convenient language in which to describe images in a device independent manner. This device independence means that the image is described without reference to any specific device features (e.g. printer resolution) so that the same description could be used on any PostScript printer (say, a LaserWriter or a Linotron) without modification.

A programming language whose instructions, when read by a Postscript interpreter, produce graphical output. Typically, Postscript programs are written by other programs like Adobe Illustrator or dvips. These are never meant to be read by humans. This talk, however, is about Postscript programs written by humans. Postscript has two beautiful features: (1) everything (well, almost) is drawn to within the accuracy of the output device and (2) everything is easily scaled.

Problem F PostScript Emulation In this problem you are required to recognize a small part of the PostScript language. Specifically, the commands listed below must be recognized. All commands will be given in lower-case letters. When the word number appears in the command description, a floating point value, with an optional sign and decimal point will be present in the input data. When two numbers appear in a command, the first refers to the x coordinate, and the second to the y coordinate. For simplicity, each command will appear on a line by itself, and a single blank will separate each component of the command. The end of line character will immediately follow each command, and a line with a single asterisk in column one will terminate the input. number rotate number represents the measure of an angle. This command rotates the coordinate system that may degrees counter clockwise about the current origin. his does not affect any lines that have already been drawn on the page. Example: 90 rotate will rotate the axes 90 degrees counterclockwise, so the positive y axis now points to the left, and the positive x axis points up.

The Sierpinski Gasket sierpinski.ps Spiral With the Golden Angle spiral.ps Penrose Tiling penrose.ps IFS Fractal Generator Iterated Function System fractals are generated by a set of affine transformations. An affine transformation is a linear transformation together with a translation. One way to draw such fractals is the following: Start at any point. Pick a random transformation in the set and apply it to the point. This defines a new point. Repeat the same procedure with the new point and so on. Draw all points after a few steps needed for convergence. This fractal generator uses another technique. First it approximates the convex hull of the fractal. Then it applies all transformations in the set recursively. At the deepest recursions, the convex hull approximation is transformed and drawn. The whole fractal generator is encapsulated in one function which calls save and restore in order to not interfere with other code. This is important if you want to use my fractal generator in your own Postscript applications.

Elizabeth's Peculiar PostScript I originally started programming in PostScript for two reasons; first, it was the most graphics-oriented language available to me, and second, it allowed me to use the CPU in the printer, and the LaserWriter was the fastest computer Apple made at the time. Also, the whole concept of a printer job that produced different results each time you printed it appealed to me. Lazy as ever, and more aware than most people of the risks of PostScript, I'm not willing to run jobs live when you load the web page. However, you can download the programs and burn your CPU cycles and printer pages at will. Unless otherwise noted, the programs are set for a high degree of randomness (which means your chances of something boring or ugly are significant, but your chances of being bored by multiple similar runs are low), and are set to fill whatever the printer thinks is a whole page with a single design. Most of them are also capable of other modes, usually including a postcard mode that does 2 4x6 postcards per page. On the other hand, I have not cleaned them up from their normal state, so other human beings may have extreme difficulty comprehending or modifying the code. Circles This program is horribly misnamed. I started it playing with circles, as an attempt to cheer up a friend who complained she was covered in spots. However, it now can pile up shapes other than circles, and usually does. Like many of these programs, this is a proof of the power of symmetry, repetition and eye-catching color in making randomness attractive.
