The filters used when scaling texture data.
The actual implementation of each filter is deferred to the rendering pipeline.
Constructors
| ScalingFilterLinear | linear interpolation filter |
| ScalingFilterNearest | nearest neighbor interpolation filter |
| ScalingFilterTrilinear | linear interpolation along each axis, plus mipmap generation, with linear interpolation along the mipmap levels |
| AnotherScalingFilter Int | Catch-all for unknown values |
Instances
SerializationError
data SerializationError Source #
Errors that can happen during (de)serialization.
Constructors
| SerializationErrorUnsupportedFormat | The format can not be identified |
| SerializationErrorUnsupportedVersion | The version of the data is not understood |
| SerializationErrorInvalidData | The given data may not exist in a proper serialization |

Instances
catchSerializationError :: IO a -> (SerializationError -> GErrorMessage -> IO a) -> IO a Source #
Catch exceptions of type SerializationError. This is a specialized version of catchGErrorJustDomain.
handleSerializationError :: (SerializationError -> GErrorMessage -> IO a) -> IO a -> IO a Source #
Handle exceptions of type SerializationError. This is a specialized version of handleGErrorJustDomain.
TransformCategory
data TransformCategory Source #
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)).
Constructors
| TransformCategoryUnknown | The category of the matrix has not been determined. |
| TransformCategoryAny | Analyzing the matrix concluded that it does not fit in any other category. |
| TransformCategory3d | The matrix is a 3D matrix. This means that the w column (the last column) has the values (0, 0, 0, 1). |
| TransformCategory2d | The matrix is a 2D matrix. This is equivalent
to |
| TransformCategory2dAffine | The matrix is a combination of 2D scale and 2D translation operations. In particular, this means that any rectangle can be transformed exactly using this matrix. |
| TransformCategory2dTranslate | The matrix is a 2D translation. |
| TransformCategoryIdentity | The matrix is the identity matrix. |
| AnotherTransformCategory Int | Catch-all for unknown values |
