Package: graphene
Macro graphene:with-quad
Lambda Listgraphene:with-quad ((var &rest args) &body body) SyntaxArgumentsDetails The graphene:with-quad macro allocates a new graphene:quad-t
instance, initializes the quadrilateral with the given values and executes
the body that uses the quadrilateral.
After execution of the body the allocated memory for the quadrilateral is
released. When no argument is given the components of the quadrilateral are initialized to zeros. The initialization with four points uses the graphene:quad-init function. The initialization from a rectangle is done with the graphene:quad-init-from-rect function. Note | See also |
