Struct
GskTransform
Description [src]
struct GskTransform {
/* No available fields */
}
GskTransform is an object to describe transform matrices.
Unlike graphene_matrix_t, GskTransform retains the steps in how
a transform was constructed, and allows inspecting them. It is modeled
after the way CSS describes transforms.
GskTransform objects are immutable and cannot be changed after creation.
This means code can safely expose them as properties of objects without
having to worry about others changing them.
