Struct glium::texture::texture2d::Texture2dMipmap

pub struct Texture2dMipmap<'t>(_, _);

Represents a single mipmap level of a Texture2d.

Can be obtained by calling Texture2d::mipmap(), Texture2d::main_level(), Texture2dLayer::mipmap() or Texture2dLayer::main_level().

Implementations

impl<'t> Texture2dMipmap<'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, u32)

Returns the width and height of that image.

pub fn write<'a, T>(&self, rect: Rect, data: T) where
    T: Texture2dDataSource<'a>, 

Uploads some data in the texture level.

Note that this may cause a synchronization if you use the texture right before or right after this call.

Panic

Panics if the the dimensions of data don't match the Rect.

pub fn get_texture(&self) -> &'t Texture2d

Returns the corresponding texture.

pub fn get_level(&self) -> u32

Returns the texture level.

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.
