Quartz isn't based on DPS - CoreGraphics drawing commands are similar to PDF but the window management was always all pixel based - and IIRC DPS was almost all Adobe and NeXT didn't even have source for it.
- reissbaker 3y agoQuartz was originally based on PDF and was marketed early on as "Display PDF" (a reference to being a more advanced version of "Display PostScript"): https://archive.arstechnica.com/reviews/1q00/macos-x-gui/macos-x-gui-4.html https://archive.arstechnica.com/reviews/1q00/macos-x-gui/mac...
- astrange 3y agoWell, it wasn't really based on PDF to the point it stores PDFs in memory or anything. Like I said, it just has compatible drawing commands. It's turned out that vector images aren't that performant or easy to deal with for various reasons, although they are still used in some places.
