Is PDFium able to read a PostScript stream?

[Sofia I.]

I didn't seem to find anything, but I was wondering if PDFium has any ability to render PostScript files?

Thank you.

I am pretty sure PDFium has the ability to render PostScript. PostScript is widely used in PDF and PDFium can render those files.

I cannot pinpoint where the code is, will need some time to read through the code.

May I ask what is your use case reading PostScript? Just curious where is PostScript used other than in a PDF file.

Thank you for your reply. I am trying to convert .PRN files to PDF format. These are PostScript-format files generated by PostScript printer drivers. I am currently using GhostScript to do this, but if PDFium can handle the task, GhostScript is not necessary.

Thank you.

Seems quite unlikely that a comprehensive PDF library such as PDFium is not able to read PostScript data. But yet I've not been able to find a single mention in any article or post as such. Nothing at all.

Might anyone here know, please?

I used postscript 25+ years ago, before pdf.

PDF solved the problems of postscript such as not having a well defined

paperspace and no clear support for multiple pages.

It also solved the problem of postscript being an unlimited general purpose

programming language. That "Feature" made proper implementation of a

postscript machine very difficult. Aside from Adobe, Ghostscript is the only

project I know of that accomplished it.

PDF is based on a subset of postscript. Which is why Ghostscript was able to support

it easily, and why ground up PDF parsers lack the ability to handle postscript.

I believe that PDFium has no support for postscript. It's only surviving use is

software inside printers.

Thank you, Scott. I'm disappointed, tbh, but at least I can move on with GhostScript. Might you possibly know if it there's any way to rebuild the GhostScript DLL?
