Methods

Arguments
| :: (HasCallStack, MonadIO m) | |
| => Quadrilateral |

| -> m Quadrilateral | Returns: a new allocated copy of |
Creates a copy of quad. The copy must be freed with quadrilateralFree after use.

free
Arguments
| :: (HasCallStack, MonadIO m) | |
| => Quadrilateral |
|
| -> m () |
Frees the memory used by quad

new
Arguments

Properties
p1
a Point with the first vertex coordinates
getQuadrilateralP1 :: MonadIO m => Quadrilateral -> m Point Source #
Get the value of the “p1” field.
When overloading is enabled, this is equivalent to
get quadrilateral #p1
p2
a Point with the second vertex coordinates
getQuadrilateralP2 :: MonadIO m => Quadrilateral -> m Point Source #
Get the value of the “p2” field.
When overloading is enabled, this is equivalent to
get quadrilateral #p2
p3
a Point with the third vertex coordinates
getQuadrilateralP3 :: MonadIO m => Quadrilateral -> m Point Source #
Get the value of the “p3” field.
When overloading is enabled, this is equivalent to
get quadrilateral #p3
p4
a Point with the fourth vertex coordinates
getQuadrilateralP4 :: MonadIO m => Quadrilateral -> m Point Source #
Get the value of the “p4” field.
When overloading is enabled, this is equivalent to
get quadrilateral #p4
