Computing sizes
width :: (InSpace V2 n a, Enveloped a) => a -> n Source #
Compute the width of an enveloped object.
Note this is just diameter unitX
.
height :: (InSpace V2 n a, Enveloped a) => a -> n Source #
Compute the height of an enveloped object.
extentX :: (InSpace v n a, R1 v, Enveloped a) => a -> Maybe (n, n) Source #
Compute the absolute x-coordinate range of an enveloped object in
the form (lo,hi)
. Return Nothing
for objects with an empty
envelope.
Note this is just extent unitX
.
extentY :: (InSpace v n a, R2 v, Enveloped a) => a -> Maybe (n, n) Source #
Compute the absolute y-coordinate range of an enveloped object in
the form (lo,hi)
. Return Nothing
for objects with an empty
envelope.
