Implementations§
source§impl Image
impl Image
sourcepub fn new(
size: Extent3d,
dimension: TextureDimension,
data: Vec<u8>,
format: TextureFormat
) -> Self
pub fn new( size: Extent3d, dimension: TextureDimension, data: Vec<u8>, format: TextureFormat ) -> Self
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.
sourcepub fn new_fill(
size: Extent3d,
dimension: TextureDimension,
pixel: &[u8],
format: TextureFormat
) -> Self
pub fn new_fill( size: Extent3d, dimension: TextureDimension, pixel: &[u8], format: TextureFormat ) -> Self
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.
do not match.
sourcepub fn resize(&mut self, size: Extent3d)
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.
sourcepub fn reinterpret_size(&mut self, new_size: Extent3d)
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.
sourcepub fn reinterpret_stacked_2d_as_array(&mut self, layers: u32)
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
.
sourcepub fn convert(&self, new_format: TextureFormat) -> Option<Self>
pub fn convert(&self, new_format: TextureFormat) -> Option<Self>
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
.
sourcepub fn from_buffer(
buffer: &[u8],
image_type: ImageType<'_>,
supported_compressed_formats: CompressedImageFormats,
is_srgb: bool
) -> Result<Image, TextureError>
pub fn from_buffer( buffer: &[u8], image_type: ImageType<'_>, supported_compressed_formats: CompressedImageFormats, is_srgb: bool ) -> Result<Image, TextureError>
Load a bytes buffer in a Image
, according to type image_type
, using the image
crate
sourcepub fn is_compressed(&self) -> bool
pub fn is_compressed(&self) -> bool
Whether the texture format is compressed or uncompressed
source§impl Image
impl Image
sourcepub fn from_dynamic(dyn_img: DynamicImage, is_srgb: bool) -> Image
pub fn from_dynamic(dyn_img: DynamicImage, is_srgb: bool) -> Image
Converts a DynamicImage
to an Image
.
sourcepub fn try_into_dynamic(self) -> Result<DynamicImage>
pub fn try_into_dynamic(self) -> Result<DynamicImage>
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
To convert Image
to a different format see: Image::convert
.
