Add images antialiasing support to PDF Viewer
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.
