Struct nannou::ui::backend::glium::glium::texture::unsigned_texture2d_multisample::UnsignedTexture2dMultisample

pub struct UnsignedTexture2dMultisample(_);

A two-dimensional texture containing unsigned integral data.

Methods

impl UnsignedTexture2dMultisample

pub fn sampled(&self) -> Sampler<UnsignedTexture2dMultisample>

Builds a Sampler marker object that allows you to indicate how the texture should be sampled from inside a shader.

Example

let uniforms = uniform! {
    color_texture: texture.sampled().magnify_filter(glium::uniforms::MagnifySamplerFilter::Nearest)
};

impl UnsignedTexture2dMultisample

pub fn get_internal_format(&self) -> Result<InternalFormat, GetFormatError>

Determines the internal format of this texture.

The backend may not support querying the actual format, in which case an error is returned.

pub fn empty<F>(     facade: &F,     width: u32,     height: u32,     samples: u32 ) -> Result<UnsignedTexture2dMultisample, TextureCreationError> where     F: Facade + ?Sized,

Creates an empty texture.

No mipmap level (except for the main level) will be allocated or generated.

The texture will contain undefined data.

pub fn empty_with_format<F>(     facade: &F,     format: UncompressedUintFormat,     mipmaps: MipmapsOption,     width: u32,     height: u32,     samples: u32 ) -> Result<UnsignedTexture2dMultisample, TextureCreationError> where     F: Facade + ?Sized,

Creates an empty texture with a specific format.

The texture (and its mipmaps) will contain undefined data.

pub fn empty_with_mipmaps<F>(     facade: &F,     mipmaps: MipmapsOption,     width: u32,     height: u32,     samples: u32 ) -> Result<UnsignedTexture2dMultisample, TextureCreationError> where     F: Facade + ?Sized,

Creates an empty texture. Specifies whether is has mipmaps.

The texture (and its mipmaps) will contain undefined data.

pub unsafe fn from_id<F>(     facade: &F,     format: UncompressedUintFormat,     id: u32,     owned: bool,     mipmap: MipmapsOption,     ty: Dimensions ) -> UnsignedTexture2dMultisample where     F: Facade + ?Sized,

Builds a new texture reference from an existing, externally created OpenGL texture. If owned is true, this reference will take ownership of the texture and be responsible for cleaning it up. Otherwise, the texture must be cleaned up externally, but only after this reference's lifetime has ended.

pub fn width(&self) -> u32

Returns the width of that image.

pub fn height(&self) -> u32

Returns the height of that image.

pub fn samples(&self) -> u32

Returns the number of samples of that image.

pub fn dimensions(&self) -> (u32, u32)

Returns the width and height of that image.

pub fn as_surface(&'a self) -> SimpleFrameBuffer<'a>

Starts drawing on the texture.

All the function calls to the framebuffer will draw on the texture instead of the screen.

Low-level information

The first time that this function is called, a FrameBuffer Object will be created and cached. The following calls to as_surface will load the existing FBO and re-use it. When the texture is destroyed, the FBO is destroyed too.

pub fn get_mipmap_levels(&self) -> u32

Returns the number of mipmap levels of the texture.

The minimum value is 1, since there is always a main texture.

pub fn resident(     self ) -> Result<ResidentTexture, BindlessTexturesNotSupportedError>

Turns the texture into a ResidentTexture.

This allows you to use the texture in a much more efficient way by storing a "reference to it" in a buffer (actually not a reference but a raw pointer).

See the documentation of ResidentTexture for more infos.

pub fn mipmap(&self, level: u32) -> Option<UnsignedTexture2dMultisampleMipmap>

Access a single mipmap level of this texture.

pub fn main_level(&self) -> UnsignedTexture2dMultisampleMipmap

Access the main mipmap level of this texture.

Methods from Deref<Target = TextureAny>

pub fn get_width(&self) -> u32

Returns the width of the texture.

pub fn get_height(&self) -> Option<u32>

Returns the height of the texture.

pub fn get_depth(&self) -> Option<u32>

Returns the depth of the texture.

pub fn kind(&self) -> TextureKind

Returns the kind of texture.

pub fn dimensions(&self) -> Dimensions

Returns the dimensions of the texture.

pub fn get_array_size(&self) -> Option<u32>

Returns the array size of the texture.

pub fn get_samples(&self) -> Option<u32>

Returns the number of samples of the texture if it is a multisampling texture.

pub fn first_layer(&self) -> TextureAnyLayer

Returns a structure that represents the first layer of the texture. All textures have a first layer.

pub fn layer(&self, layer: u32) -> Option<TextureAnyLayer>

Returns a structure that represents a specific layer of the texture.

Non-array textures have only one layer. The number of layers can be queried with get_array_size.

Returns None if out of range.

pub fn get_texture_type(&self) -> Dimensions

Returns the type of the texture (1D, 2D, 3D, etc.).

pub fn get_internal_format(&self) -> Result<InternalFormat, GetFormatError>

Determines the internal format of this texture.

pub fn get_mipmap_levels(&self) -> u32

Returns the number of mipmap levels of the texture.

pub fn main_level(&self) -> TextureAnyMipmap

Returns a structure that represents the main mipmap level of the texture.

pub fn mipmap(&self, level: u32) -> Option<TextureAnyMipmap>

Returns a structure that represents a specific mipmap of the texture.

Returns None if out of range.

pub unsafe fn generate_mipmaps(&self)

Binds this texture and generates mipmaps.
