Declares a two-dimensional texture sampler.

Fields

source: NameRef<Surface>

A name, which is the sid of a Surface. A Sampler* is a definition of how a shader will resolve a color out of a Surface. source identifies the Surface to read.

wrap_s: WrapMode

Wrap mode in the first texture coordinate.

wrap_t: WrapMode

Wrap mode in the second texture coordinate.

min_filter: SamplerFilter

Texture minimization. Applying a texture to a primitive implies a mapping from texture image space to framebuffer image space. In general, this mapping involves a reconstruction of the sampled texture image, followed by a homogeneous warping implied by the mapping to framebuffer space, then a filtering, followed finally by a resampling of the filtered, warped, reconstructed image before applying it to a fragment.

mag_filter: SamplerFilter

Texture magnification. Enumerated type fx_sampler_filter_common. When gamma indicates magnification, this value determines how the texture value is obtained.

mip_filter: SamplerFilter

MIPmap filter.

border_color: Option<Box<[f32; 4]>>

When reading past the edge of the texture address space based on the wrap modes involving clamps, this color takes over. Type fx_color_common (four floating-point numbers in RGBA order).

mipmap_max_level: u8

The maximum number of progressive levels that the sampler will evaluate.

mipmap_bias: f32

Biases the gamma (level of detail parameter) that is used by the sampler to evaluate the MIPmap chain.

extra: Vec<Extra>

Provides arbitrary additional information about this element.
