Module gfx::texture [−][src]
Texture creation and modification.
“Texture” is an overloaded term. In gfx-rs, a texture consists of two separate pieces of information: image storage description (which is immutable for a single texture object), and image data. To actually use a texture, a “sampler” is needed, which provides a way of accessing the image data. Image data consists of an array of “texture elements”, or texels.
Structs
| DepthStencilDesc | Texture depth-stencil view descriptor. |
| DepthStencilFlags | Depth-stencil read-only flags |
| ImageInfoCommon | Describes a subvolume of a texture, which image data can be uploaded into. |
| Info | Texture storage descriptor. |
| Lod | A wrapper for the LOD level of a texture. |
| PackedColor | A wrapper for the 8bpp RGBA color, encoded as u32. |
| Raw | Untyped texture |
| RenderDesc | Texture render view descriptor. |
| ResourceDesc | Texture resource view descriptor. |
| SamplerInfo | Specifies how to sample from a texture. |
| TextureCopyRegion | A texture region defined for copy operations |
Enums
| AaMode | Describes the configuration of samples inside each texel. |
| CreationError | Pure texture object creation error. |
| CubeFace | The face of a cube texture to do an operation on. |
| FilterMethod | How to filter the texture when sampling. They correspond to increasing levels of quality, but also cost. Mipmap, trilinear and anisotropic filtering require mipmapping, but the other filtering methods do not. |
| Kind | Specifies the kind of a texture storage to be allocated. |
| LayerError | An error associated with selected texture layer. |
| Mipmap | The marker for the texture initializer to generate extra space for the mipmap generation. |
| WrapMode | Specifies how texture coordinates outside the range |
Constants
| CUBE_FACES | A constant array of cube faces in the order they map to the hardware. |
| MAX_LEVEL | Maximum accessible mipmap level of a texture. |
Type Definitions
| Bits | Number of bits per component |
| Dimensions | Dimensions: width, height, depth, and samples. |
| Layer | A depth value, specifying which plane to select out of a 3D texture. |
| Level | Mipmap level to select in a texture. |
| NewImageInfo | New image info based on the universal format spec. The format is suppsed to come from compile-time information as opposed to run-time enum values. |
| NumFragments | Number of EQAA fragments |
| NumSamples | Number of MSAA samples |
| RawImageInfo | New raw image info based on the universal format spec. |
| Size | Dimension size |
