About

Ghostscript is a suite of software based on an interpreter for Adobe Systems' PostScript and Portable Document Format (PDF) page description languages.

Ghostscript can be used as a raster image processor (RIP) for raster computer printers — for instance, as an input filter of line printer daemon — or as the RIP engine behind PostScript and PDF viewers.

Ghostscript can also be used as a file format converter, such as PostScript to PDF converter; this is often combined with a PostScript printer driver in "virtual printer" PDF creators.

As it takes the form of a language interpreter, Ghostscript can also be used as a general purpose programming environment.

Ghostscript has been ported to many operating systems, including most Unix and Unix-like systems (including Linux), Mac OS, OpenVMS, Microsoft Windows, OS/2 and AmigaOS.

Frontends

Several graphical user interfaces have been written for use with Ghostscript which permit a user to view a PostScript or PDF file on screen, scroll, page forward and backward, and zoom the text as well as print single or multiple pages.

  • Ghostview runs under Unix/X11. Ghostview has an unusual (and arguably counter-intuitive) user interface feature: dragging the mouse over the image pans the image in the opposite direction (the mouse moves the viewport over the image, rather than the image underneath the viewport). The effect is similar to having invisible scroll bars all over the image and is approximately the opposite of panning in Google Maps and other applications.
  • gv runs under Unix/X11. gv is a visually improved version of Ghostview. Its behaviour is similar to Ghostview.
  • mgv runs under Unix/X11. It is a Motif (widget toolkit) based front-end to Ghostscript. It features a more conventional user interface, with regular menus, a toolbar, and scrollbars.
  • GSview runs under Microsoft Windows, OS/2, and UNIX-like operating systems. It is best known for its Windows and OS/2 versions. On UNIX it uses the GTK+ toolkit.
  • Although under a public license, GSview also employs a nag screen to urge users to register so as to support the development of GS. The registration fee is AUD$40.

PHP: tiff2pdf

Or: How to convert multipage TIFF to PDF in PHP. Let's say you have a fax with multiple pages that has been stored as a TIFF and you want to convert it to PDF using PHP for digital document flow. In this article I will show you a tiff2pdf function for PHP, because it cannot be done directly with ImageMagick.
