Comment on PDFium: Chrome’s PDF rendering engine is now open-sourceparent

Comments

i dont know, on recent computers, more often than not i dont really see a diff between pdf.js and others as a user.

it seems to only be an issue on really heavy pdfs, which are pretty rare

I've found pdf.js to be a negative user experience on most pdfs I try to view. From what I've read, this is mainly because pdf.js directly renders to a canvas, and doesn't store decoded vector information. Other readers seem to be able to zoom instantly, even for vector graphics.

Firefox also seems to register two separate mime-types for pdf, only giving an option to use pdf.js on one of them. I've yet to dig into firefox and fix this.

The speed of pdf.js on older computers is abysmal compared to native applications like okular.

Think mobile.

On mobile (Android) both Fx and Chrome start downloading pdfs.

On mobile, both Firefox and Chrome download PDFs to be rendered by another app on Android. I'm unsure about Chrome on iOS. There is no Firefox for iOS because Apple.
