MediaTrackConstraints: height property
The MediaTrackConstraints
dictionary's
height
property is a ConstrainULong
describing the requested or mandatory constraints placed upon the value of the
height
constrainable property.
If needed, you can determine whether or not this constraint is supported by checking
the value of MediaTrackSupportedConstraints.height
as returned by a call
to MediaDevices.getSupportedConstraints()
. However, typically this is
unnecessary since browsers will ignore any constraints they're unfamiliar with.
Value
If this value is a number, the user agent will attempt to obtain media whose height is
as close as possible to this number given the capabilities of the hardware and the other
constraints specified. Otherwise, the value of this ConstrainULong
will
guide the user agent in its efforts to provide an exact match to the required height (if
exact
is specified or both min
and max
are
provided and have the same value) or to a best-possible value.
Examples
See the Constraint exerciser example.
