Struct glium::texture::compressed_texture3d::CompressedTexture3dMipmap

pub struct CompressedTexture3dMipmap<'t>(_, _);

Represents a single mipmap level of a CompressedTexture3d.

Can be obtained by calling CompressedTexture3d::mipmap(), CompressedTexture3d::main_level(), CompressedTexture3dLayer::mipmap() or CompressedTexture3dLayer::main_level().

Methods

impl<'t> CompressedTexture3dMipmap<'t>

fn width(&self) -> u32

Returns the width of that image.

fn height(&self) -> u32

Returns the height of that image.

fn depth(&self) -> u32

Returns the depth of that image.

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

Returns the width, height and depth of that image.

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.

fn get_texture(&self) -> &'t CompressedTexture3d

Returns the corresponding texture.

fn get_level(&self) -> u32

Returns the texture level.

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

fn get_width(&self) -> u32

Returns the width of the mipmap.

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

Returns the height of the mipmap.

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

Returns the depth of the mipmap.

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

Returns the number of samples of the texture.

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

Returns the texture.

fn get_level(&self) -> u32

Returns the level of the texture.

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.

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.

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

Returns the array size of the texture.

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.

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.
