Struct

GskTransform

Description [src] 

struct GskTransform {
  /* No available fields */
}

Describes a 3D transform.

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.
