Converts an unpacked complex data value holding a dimension to its final floating point pixel value.

[Android.Runtime.Register("applyDimension", "(IFLandroid/util/DisplayMetrics;)F", "")]
public static float ApplyDimension (Android.Util.ComplexUnitType unit, float value, Android.Util.DisplayMetrics? metrics);

[<Android.Runtime.Register("applyDimension", "(IFLandroid/util/DisplayMetrics;)F", "")>]
static member ApplyDimension : Android.Util.ComplexUnitType * single * Android.Util.DisplayMetrics -> single

Parameters

unit: ComplexUnitType

The unit to convert from.

value: Single

The value to apply the unit to.

metrics: DisplayMetrics

Current display metrics to use in the conversion -- supplies display density and scaling information.

Returns

Single

The equivalent pixel value—i.e. the complex floating point value multiplied by the appropriate metrics depending on its unit—or zero if unit is not valid.

Attributes: RegisterAttribute

Remarks

Converts an unpacked complex data value holding a dimension to its final floating point pixel value. The two parameters <var>unit</var> and <var>value</var> are as in #TYPE_DIMENSION.

To convert the other way, e.g. from pixels to DP, use #deriveDimension(int, float, DisplayMetrics).
