Toot

SVG, HTML5 Canvas, Apple Core Graphics, PDF, and probably many others all use the same core vector graphics model and operators, which I think of as from PostScript.

Did the creators of PostScript invent these, did they originate in some even earlier system?

@rsc https://en.wikipedia.org/wiki/Interpress might be the most direct ancestor I think

@rsc The creators of PostScript while they were at Xerox PARC. https://spectrum.ieee.org/adobe-postscript-code

@rsc multiple independent systems led to similar concepts. For example, Knuth and Hobby's work on MetaFont and MetaPost was developed in the same years as PostScript and reached a similar design (IIRC, the work on MF and MP actually started earlier).

@rsc that being said, PDF is explicitly based on PostScript, and Apple Core Graphics IIRC is similarly explicitly inspired by PDF (and thus on PS), so for those the lineage is clear. HTML5 Canvas takes from SVG, SVG itself came from several different proposals among which one co-developed by Adobe (PGML, which was explicitly based on the PS/PDF image model, see https://www.w3.org/TR/1998/NOTE-PGML-19980410), so one could consider them part of the PS lineage.

@rsc the Forth relationship is fairly clear - Forth provides the programming model and PostScript adds the graphics primitives. That it doesn't share code with a Forth precursor hardly matters given the simplicity of a Forth implementation.
