PostScript

PostScript is a stack-based page description language and programming language used extensively in desktop publishing, graphics processing, and printing.

Installation

On Ubuntu, PostScript files can be rendered, interpreted, and processed using Ghostscript (gs).

Run the following command in TIDE's terminal:

sudo apt update
sudo apt install -y ghostscript

Verification

Check the Ghostscript version:

gs --version

Writing and Running Code

Create a file named hello.ps:

%!PS
(Hello, World from PostScript!\n) print
quit

Run the PostScript program using Ghostscript in batch quiet mode:

gs -q -ND -dBATCH hello.ps

Visual Output Example

%!PS
/Helvetica findfont 24 scalefont setfont
100 500 moveto
