Struct nannou::ui::backend::glium::glium::texture::compressed_cubemap::CompressedCubemapMipmap

pub struct CompressedCubemapMipmap<'t>(_, _);

Represents a single mipmap level of a CompressedCubemap.

Can be obtained by calling CompressedCubemap::mipmap(), CompressedCubemap::main_level(), CompressedCubemapLayer::mipmap() or CompressedCubemapLayer::main_level().

Methods

impl<'t> CompressedCubemapMipmap<'t>

pub fn width(&self) -> u32

Returns the width of that image.

pub fn height(&self) -> u32

Returns the height of that image.

pub fn dimensions(&self) -> u32

Returns the dimension of that image.

pub fn read_compressed_data(&self) -> Option<(CompressedFormat, Vec<u8>)>

Reads the content of the texture level to RAM without decompressing it before.

You should avoid doing this at all cost during performance-critical operations (for example, while you're drawing).

Returns the compressed format of the texture and the compressed data, gives None when the internal compression format is generic or unknown.

pub fn get_texture(&self) -> &'t CompressedCubemap

Returns the corresponding texture.

pub fn get_level(&self) -> u32

Returns the texture level.

pub fn image(&self, layer: CubeLayer) -> CompressedCubemapImage<'t>

Provides an object representing a single layer of this cubemap.

Methods from Deref<Target = TextureAnyMipmap<'a>>

pub fn get_width(&self) -> u32

Returns the width of the mipmap.

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

Returns the height of the mipmap.

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

Returns the depth of the mipmap.

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

Returns the number of samples of the texture.

pub fn get_texture(&self) -> &'a TextureAny

Returns the texture.

pub fn get_level(&self) -> u32

Returns the level of the texture.

pub fn first_layer(&self) -> TextureAnyLayerMipmap<'a>

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

pub fn layer(&self, layer: u32) -> Option<TextureAnyLayerMipmap<'a>>

Returns a structure that represents a specific layer of this mipmap 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_array_size(&self) -> Option<u32>

Returns the array size of the texture.

pub fn raw_upload_from_pixel_buffer<P>(     &self,     source: BufferSlice<[P]>,     x: Range<u32>,     y: Range<u32>,     z: Range<u32> ) where     P: PixelValue,

Uploads data to the texture from a buffer.

Panic

Panics if the offsets and dimensions are outside the boundaries of the texture. Panics if the buffer is not big enough to hold the data.

pub fn raw_upload_from_pixel_buffer_inverted<P>(     &self,     source: BufferSlice<[P]>,     x: Range<u32>,     y: Range<u32>,     z: Range<u32> ) where     P: PixelValue,

Uploads data to the texture from a buffer. The R, G and B components are flipped.

Panic

Panics if the offsets and dimensions are outside the boundaries of the texture. Panics if the buffer is not big enough to hold the data.

Trait Implementations
