Informal Description

The 'pixelDensity' property in this domain represents the physical resolution of an image resource. The value of the pixelDensity property should be either a numeric value, which will be assumed to represent the pixels per inch (ppi) of the resource, or a string containing a number followed by a space and then a string representing the units in use. For example, '300 ppi'. The following units are commonly-used and suitable for this property:

ppi - pixels per inch
ppm - pixels per meter
ppcm - pixels per centimeter
ppmm - pixels per millimeter
...and so-on.

Alph Implementation Note:

Image resources that do not publish this property will be assumed within the Alph software to be 96 ppi.
