Ghostscript
Ghostscript is an interpreter for the PostScript language and PDF files, used for rendering, converting, and processing page description languages. It provides a command-line interface and library APIs to handle tasks like viewing, printing, and transforming documents between formats such as PDF, PostScript, and various image types. It is widely used in server environments, printing systems, and document processing pipelines.
Developers should learn Ghostscript when working with document processing systems that require automated conversion, rendering, or manipulation of PDF and PostScript files, such as in web applications for generating reports, batch processing in print shops, or integrating with document management software. It is essential for tasks like extracting text, compressing PDFs, converting documents to images, or handling printer workflows in Linux/Unix environments.
