This html5rocks.com article on High DPI Canvas has been recommended in several places through SO. It describes how to use the backingStoreRatio value to properly scale bitmaps on high-resolution screens (retina, etc.). But I can’t find an additional link to the backingStoreRatio attribute in the MDN link to CanvasRenderingContext2D and with no other permissions on the Internet.
Is this solution valid or outdated? What is the recommended solution for drawing raster images on canvas on high resolution displays?
