Some pdf files (e.g. sheet music, scanned books) look bad without this feature in comparison with standalone pdf viewers (Adobe Acrobat on Windows, Evince on Linux etc.). Screenshots: Evince - http://uppix.net/a/1/8/d6d2506543b7ef7eb07419a55e6ac.png Firefox - http://uppix.net/8/8/d/f055b282d23b3a23fa23d4a76cf89.png Simple example is attached. Please, add this feature to pdf.js, it would significantly improve readability of such files.

Maybe you could try with and without hardware acceleration in Firefox to see if it changes something

I have tried this (both azure and layers acceleration). No changes.

Indeed, the way that PDF Viewer currently displays those PDFs could be improved.

Type3 fonts anti-aliasing was implemented in https://github.com/mozilla/pdf.js/pull/1763 and part of the Nightly. See FF16 bug 778398: > #1763 Type3 smoothing: pre-scale image in the paintImageMaskXObject More on the subject and its performance, see bug 759172
