Can my AI agent convert PostScript Plot File to CDR?
Yes. Install the Filestar CLI with npm install -g filestar and your agent can run filestarcli -i photo.plt -c "convert to cdr" on your computer, so your files stay on it.
A PostScript page description saved with a .plt extension (ISR Caddsman plot files do this). Not the HP-GL plotter format that shares the .plt extension - Filestar converts it like any PostScript file, e.g. to PDF.
A CDR file is a drawing (or vector image) created with CorelDRAW, a vector illustration and page layout program. It contains a document that contains text, lines, shapes, images, colors, and effects. CDR files are used to create various types of documents such as letters, brochures, tabloids, envelopes, postcards, web pages, and web banners.
