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
| ImageInfo |
Describes a subvolume of a texture, which image data can be uploaded into. |
| SamplerInfo |
Specifies how to sample from a texture. |
| SurfaceInfo |
Describes the storage of a surface. |
| TextureInfo |
Describes the storage of a texture. |
Enums
| AaMode |
Describes the configuration of samples inside each texel. |
| ComparisonMode |
Specified how the Comparison operator should be used when sampling |
| Components |
Describes the color components of each texel. |
| Compression |
Codec used to compress image data. |
| 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. They "layer" on top of each other: it is not possible to have bilinear filtering without mipmapping, for example. |
| Format |
Describes the layout of each texel within a surface/texture. |
| SurfaceError |
Surface creation/update error. |
| TextureError |
Texture creation/update error. |
| TextureKind |
Specifies how a given texture may be used. The available texture types are
restricted by what Metal exposes, though this could conceivably be
extended in the future. Note that a single texture can only ever be of
one kind. A texture created as |
| WrapMode |
Specifies how texture coordinates outside the range |
Statics

A single R-component 8-bit normalized format. |
| RGBA16F |
A standard RGBA 16-bit floating-point format. |
| RGBA32F |
A standard RGBA 32-bit floating-point format. |
| RGBA8 |
A standard RGBA 8-bit normalized format. |
Type Definitions
