### 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.
