public float getPixelScale()

Gets the scale representing how large an area a 72DPI virtual pixel covers in terms of the pixels of this image. A 72DPI platform image would return 1.0f. A 144DPI platform image would return 2.0f.

Returns:float: the number of actual image pixels per 72DPI virtual pixel
