The _TextureVertexSizeCheckRef type acts as a lightweight Swift reference to an underlying _CoglTextureVertexSizeCheck instance. It exposes methods that can operate on this data type through _TextureVertexSizeCheckProtocol conformance. Use _TextureVertexSizeCheckRef only as an unowned reference to an existing _CoglTextureVertexSizeCheck instance.

The BitmapRef type acts as a lightweight Swift reference to an underlying CoglBitmap instance. It exposes methods that can operate on this data type through BitmapProtocol conformance. Use BitmapRef only as an unowned reference to an existing CoglBitmap instance.

A structure for holding a color definition. The contents of the CoglColor structure are private and should never by accessed directly.

The ColorRef type acts as a lightweight Swift reference to an underlying CoglColor instance. It exposes methods that can operate on this data type through ColorProtocol conformance. Use ColorRef only as an unowned reference to an existing CoglColor instance.

The EulerRef type acts as a lightweight Swift reference to an underlying CoglEuler instance. It exposes methods that can operate on this data type through EulerProtocol conformance. Use EulerRef only as an unowned reference to an existing CoglEuler instance.

The MaterialRef type acts as a lightweight Swift reference to an underlying CoglMaterial instance. It exposes methods that can operate on this data type through MaterialProtocol conformance. Use MaterialRef only as an unowned reference to an existing CoglMaterial instance.

The MaterialLayerRef type acts as a lightweight Swift reference to an underlying CoglMaterialLayer instance. It exposes methods that can operate on this data type through MaterialLayerProtocol conformance. Use MaterialLayerRef only as an unowned reference to an existing CoglMaterialLayer instance.

A CoglMatrix holds a 4x4 transform matrix. This is a single precision, column-major matrix which means it is compatible with what OpenGL expects.

A CoglMatrix can represent transforms such as, rotations, scaling, translation, sheering, and linear projections. You can combine these transforms by multiplying multiple matrices in the order you want them applied.

The transformation of a vertex (x, y, z, w) by a CoglMatrix is given by:

  x_new = xx * x + xy * y + xz * z + xw * w
  y_new = yx * x + yy * y + yz * z + yw * w
  z_new = zx * x + zy * y + zz * z + zw * w
  w_new = wx * x + wy * y + wz * z + ww * w

Where w is normally 1

<note>You must consider the members of the CoglMatrix structure read only, and all matrix modifications must be done via the cogl_matrix API. This allows Cogl to annotate the matrices internally. Violation of this will give undefined results. If you need to initialize a matrix with a constant other than the identity matrix you can use cogl_matrix_init_from_array().</note>

The MatrixRef type acts as a lightweight Swift reference to an underlying CoglMatrix instance. It exposes methods that can operate on this data type through MatrixProtocol conformance. Use MatrixRef only as an unowned reference to an existing CoglMatrix instance.

Types of auxiliary buffers

Target flags for FBOs.

Defines a bit mask of color channels. This can be used with cogl_pipeline_set_color_mask() for example to define which color channels should be written to the current framebuffer when drawing something.

Flags for the supported features.

Flags for cogl_framebuffer_read_pixels_into_bitmap()

Flags to pass to the cogl_texture_new_* family of functions.
