Convert GIMP XCF to PostScript

XCF (eXperimental Computing Facility) is the native project file format for the GNU Image Manipulation Program (GIMP). It is a binary format designed to save all data associated with a GIMP editing session, including layers, channels, paths, transparency (alpha), and guides. The file structure relies on a pointer-based system to reference image tiles and uses simple Run-Length Encoding (RLE) for compressing pixel data. XCF is strictly a working format for image editing and is not intended for final image distribution or web rendering.

The XCF format is proprietary to GIMP and should be opened using the GNU Image Manipulation Program on Windows, macOS, or Linux to preserve layer structure and editability. While some third-party viewers like IrfanView (with plugins), XnView, and Inkscape can import or view flattened versions of XCF files, they cannot write or edit the multilayered data natively. Operating systems do not provide native rendering support for XCF files.

PostScript (PS) is a dynamically typed, concatenative page description language developed by Adobe Systems, serving as the predecessor to the PDF format. It describes text and graphics on a page using vector graphics instructions rather than rasterized pixels, making it resolution-independent. A PS file contains a program written in the PostScript language, which is interpreted by a Raster Image Processor (RIP) to generate the print output. It supports distinct imaging models, including Type 1 fonts and color separations, and became the standard for desktop publishing and high-end printing workflows in the 1980s and 90s.

Opening PS files requires software capable of interpreting the PostScript language, as modern OS image viewers do not support it natively. Ghostscript is the standard open-source interpreter used to view and convert PS files. For GUI-based editing and viewing, Adobe Illustrator and CorelDRAW can import PS files. Users can also convert PS files to PDF using tools like ps2pdf (part of the Ghostscript suite) for easier accessibility.
