class Gsk::Transform

• Gsk::Transform
• Reference
• Object

Overview

Gsk::Transform is an object to describe transform matrices.

Unlike graphene_::matrix_t, Gsk::Transform retains the steps in how a transform was constructed, and allows inspecting them. It is modeled after the way CSS describes transforms.

Gsk::Transform 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.

Defined in:

lib/gi-crystal/src/auto/gsk-4.0/transform.cr
