TransformCategory

Description:

[ CCode ( cprefix = "GSK_TRANSFORM_CATEGORY_" , type_id = "gsk_transform_category_get_type ()" ) ]
public enum TransformCategory

The categories of matrices relevant for GSK and GTK.

Note that any category includes matrices of all later categories. So if you want to for example check if a matrix is a 2D matrix, `category >= GSK_TRANSFORM_CATEGORY_2D` is the way to do this.

Also keep in mind that rounding errors may cause matrices to not conform to their categories. Otherwise, matrix operations done via multiplication will not worsen categories. So for the matrix multiplication `C = A * B`, `category(C) = MIN (category(A), category(B))`.

Enum values:

  • @2D - The matrix is a 2D matrix.
  • @2D_AFFINE - The matrix is a combination of 2D scale and 2D translation operations.
  • @2D_TRANSLATE - The matrix is a 2D translation.
  • @3D - The matrix is a 3D matrix.
  • ANY - Analyzing the matrix concluded that it does not fit in any other category.
  • IDENTITY - The matrix is the identity matrix.
  • UNKNOWN - The category of the matrix has not been determined.
