/// sp|dp to px
|
|
// Google's Material design specs are in 'sp' or 'dp' which are not css units
|
|
// 'dp' is 'density independant pexels' and 'sp' is 'scale-independent pixels' (same as dp, but will be scaled by the user's font size preference)
|
|
// Android gives a 160dpi base value to 'sp' and 'dp', but Google's examples seems to use 'sp' as 'px'
|
|
// We define a scaling factor in case we need to adjust
|
|
// 'sp' is scale to 1 css-px for a rem-base-value of 16px (default)
|
|
// 'dp' is scale to 1 css-px according to scaling factor
|
|
//
|
|
// sp-to-px converts a 'sp' value to css-pixel value. Units, if specified will be stripped
|
|
// dp-to-px converts a 'dp' value to css-pixel value. Units, if specified will be stripped
|
|
//
|
|
// @param {number} $value - sp or dp value to convert.
|
|
//
|
|
// @return {number} in px.
