-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi,
I did some 'research' into the pixel density 'thing' and this is a *quick* overview, followed by my suggestion. Pixel density in Pixels per Inch [PPI] is used by Apple, LG and others to describe a screen's [or camera's] resolution. [1] However, Google Android uses dots per inch [pixels are made up of dots]. [2,3] When it comes to rendering, a device's pixel-ratio [4] is key. It is available in uaprofiles and ties in with W3C, HTML and CSS standards [5,6,7,8] So, I suggest : - - Pixel Ratio : covers all, included in uaprofiles and ties in with HTML, CSS etc. - - Pixel Density : added when available, but a unit of measure [ppi, dpi, ppcm] *must* be supplied to accommodate pixels and dots and the metric variants in use. Quick note on general name formats. For property and other names, I would like to avoid *all* punctuation marks or any other characters that may require encoding depending on serialization/transport. It's *just* practical : if we can avoid 'trouble' we must [defensive programming]. I know strong 'feelings' exist on this matter. I just urge you to be practical rather than 'politically correct'. esjr [1] http://en.wikipedia.org/wiki/Pixel_density [2] http://developer.android.com/guide/topics/resources/providing-resources.html#AlternativeResources [3] http://techcrunch.com/2010/07/21/a-quick-psa-on-dots-versus-pixels-in-lcds/ [4] http://bjango.com/articles/min-device-pixel-ratio/ [5] http://www.w3.org/TR/2002/WD-css3-background-20020802/#background-size [6] https://developer.mozilla.org/en-US/docs/Web/Guide/CSS/Media_queries#-moz-device-pixel-ratio [7] http://www.devicepixelratio.com/ [8] http://stackoverflow.com/questions/8785643/what-exactly-is-device-pixel-ratio -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.22 (MingW32) iQEcBAEBAgAGBQJUBuG8AAoJEOxywXcFLKYc33EIAKE2ydCjgP1YfeLiAqqs39tX /om3Pg2lHyV7fN2PGrnQoJPEqnisEWxqBl8P4ONB+jmQlf/G7ye8hw4APAO9c07y 9Ixx9r9e7/TCO03d/IPQtc0LLWLd9RAZLAl04mqSBTlBf188PCeJQeKa6WMVLLRA iH4mxEDsLFU9sfnT3z3cfGp/jCOSoB5vwXTD2MNfYPpPXG0ggxYhSPXDHGGKgUSN Zevcf1KT9m2hPiupw1xQytgyWHsqCrrJXS4/SkfCuykYeQAWt8oB+VrVlSHqiwN1 N9eyuPFYZkgmVZKcEDexkXH/PHLbZS/1KSmoBCW+NmjrwvqvKnIBdulAgSkpwFo= =o93E -----END PGP SIGNATURE-----
