Implementations§

source§

impl Image

source

pub fn new( size: Extent3d, dimension: TextureDimension, data: Vec<u8>, format: TextureFormat, asset_usage: RenderAssetUsages ) -> Image

Creates a new image from raw binary data and the corresponding metadata.

Panics

Panics if the length of the data, volume of the size and the size of the format do not match.

source

pub fn new_fill( size: Extent3d, dimension: TextureDimension, pixel: &[u8], format: TextureFormat, asset_usage: RenderAssetUsages ) -> Image

Creates a new image from raw binary data and the corresponding metadata, by filling the image data with the pixel data repeated multiple times.

Panics

Panics if the size of the format is not a multiple of the length of the pixel data.

source

pub fn width(&self) -> u32

Returns the width of a 2D image.

source

pub fn height(&self) -> u32

Returns the height of a 2D image.

source

pub fn aspect_ratio(&self) -> AspectRatio

Returns the aspect ratio (width / height) of a 2D image.

source

pub fn size_f32(&self) -> Vec2

Returns the size of a 2D image as f32.

source

pub fn size(&self) -> UVec2

Returns the size of a 2D image.

source

pub fn resize(&mut self, size: Extent3d)

Resizes the image to the new size, by removing information or appending 0 to the data. Does not properly resize the contents of the image, but only its internal data buffer.

source

pub fn reinterpret_size(&mut self, new_size: Extent3d)

Changes the size, asserting that the total number of data elements (pixels) remains the same.

Panics

Panics if the new_size does not have the same volume as to old one.

source

pub fn reinterpret_stacked_2d_as_array(&mut self, layers: u32)

Takes a 2D image containing vertically stacked images of the same size, and reinterprets it as a 2D array texture, where each of the stacked images becomes one layer of the array. This is primarily for use with the texture2DArray shader uniform type.

Panics

Panics if the texture is not 2D, has more than one layers or is not evenly dividable into the layers.

source

pub fn convert(&self, new_format: TextureFormat) -> Option<Image>

Convert a texture from a format to another. Only a few formats are supported as input and output:

  • TextureFormat::R8Unorm
  • TextureFormat::Rg8Unorm
  • TextureFormat::Rgba8UnormSrgb

To get Image as a image::DynamicImage see: Image::try_into_dynamic.

source

pub fn from_buffer( buffer: &[u8], image_type: ImageType<'_>, supported_compressed_formats: CompressedImageFormats, is_srgb: bool, image_sampler: ImageSampler, asset_usage: RenderAssetUsages ) -> Result<Image, TextureError>

Load a bytes buffer in a Image, according to type image_type, using the image crate

source

pub fn is_compressed(&self) -> bool

Whether the texture format is compressed or uncompressed

source§

impl Image

source

pub fn from_dynamic( dyn_img: DynamicImage, is_srgb: bool, asset_usage: RenderAssetUsages ) -> Image

Converts a DynamicImage to an Image.

source

pub fn try_into_dynamic(self) -> Result<DynamicImage, IntoDynamicImageError>

Convert a Image to a DynamicImage. Useful for editing image data. Not all TextureFormat are covered, therefore it will return an error if the format is unsupported. Supported formats are:

  • TextureFormat::R8Unorm
  • TextureFormat::Rg8Unorm
  • TextureFormat::Rgba8UnormSrgb
  • TextureFormat::Bgra8UnormSrgb

To convert Image to a different format see: Image::convert.
