:puzzle_piece: What are Ghostscript and Imagick, and Why Are They Required?

:page_facing_up: Ghostscript

Ghostscript is a suite of software that provides an interpreter for the PostScript language and for PDF files. It allows your server to convert, view, or print PDFs and PostScript files.

:small_blue_diamond: Why it’s needed:
Ghostscript is essential if your application handles PDF files — especially for generating thumbnails, converting pages to images (e.g., JPG/PNG), or printing.

Imagick is used for image manipulation, such as:
