PostScript

Contains PostScript code that can be used with any PostScript interpreter or converter (ex. Acrobat). I made a choice of using Ghostview directly, because one can use some Ghostscript features using shortcuts in Windows.Ghostscript is a stable software that will continue to be used as time passes by.

Examples

This directory contains code that are examples to use PostScript as a graphics script language. For example, details to convert Postscript to Java is given.

Opentype Fonts in PostScript

This project is a modification of Glyph Inspector that generates a PostScript file with all glyphs (all ASCII printable characters, in fact) and other information (width table - len array-, and kerning pairs table - kern array -) of the font file read with the program.

EASY DOWNLOAD: download raw glyph-inspector.html, site.css, and opentype.js. Notice that opentype.js must be in a local dist directory as shown in this directory. The other files appearing in dist directory here are just optional versions of opentype.js.

The program was written in JavaScript and it was added a button that triggers the convertion of the Opentype font file loaded by the user. Once triggered, the browser tab where it was run becomes an html text file containing the font information of the original Opentype font, but expressed in PostScript language. The file is not a PostScript font, but it has all elements to display texts using the glyphs of the original OpenType font (actually a font like structure can be contructed with it, but that is out of the scope of this project). Copying the file to a text file and renaming it with a ".ps" becomes a PostScript program able to display any of the converted glyphs of the font.

Example verdana.ps

As an example, verdana.ps was obtained by loading Verdana font, converting it to PostScript, copying the resulting page to a text file, and adding the following lines at the end:

two
fill
showpage

This code simply displays the Verdana glyph for the number 2. Notice the reserved words fill, that indicates to fill the glyph instead of stroking (use stroke to stroke only), and showpage that displays the page (necessary because it's not an EPS file).

Notice that the commands right before the new typed commands translates and scales the glyph, respectivelly:

50 110 translate
0.2 0.2 scale

These commands were generated by the convertion program for convenience. They can and should be moved to just before "two" function call, in order to make it easier to modify the translation and scale, to, for example, write texts with.

This example is further discussed in Displaying Truetype Glyphs in PostScript.

3D Visualization Software

This directory contains an example generated with the 3D visualization software I have developped in PostScript.
