Implementations

impl Image

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.

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.

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.

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.

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.

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

pub fn is_compressed(&self) -> bool

Whether the texture format is compressed or uncompressed

impl Image

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

Converts a DynamicImage to an Image.

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.
