Struct ScreenshotCaptured 

pub struct ScreenshotCaptured {
    pub entity: Entity,
    pub image: Image,
}

Fields

entity: Entity

image: Image

Methods from Deref<Target = Image>

pub fn width(&self) -> u32

Returns the width of a 2D image.

pub fn height(&self) -> u32

Returns the height of a 2D image.

pub fn aspect_ratio(&self) -> AspectRatio

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

pub fn size_f32(&self) -> Vec2

Returns the size of a 2D image as f32.

pub fn size(&self) -> UVec2

Returns the size of a 2D image.

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 scale the contents of the image.

If you need to keep pixel data intact, use Image::resize_in_place.

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 resize_in_place(&mut self, new_size: Extent3d)

Resizes the image to the new size, keeping the pixel data intact, anchored at the top-left. When growing, the new space is filled with 0. When shrinking, the image is clipped.

For faster resizing when keeping pixel data intact is not important, use Image::resize.

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 is_compressed(&self) -> bool

Whether the texture format is compressed or uncompressed

pub fn pixel_data_offset(&self, coords: UVec3) -> Option<usize>

Compute the byte offset where the data of a specific pixel is stored

Returns None if the provided coordinates are out of bounds.

For 2D textures, Z is the layer number. For 1D textures, Y and Z are ignored.

pub fn pixel_bytes(&self, coords: UVec3) -> Option<&[u8]>

Get a reference to the data bytes where a specific pixel’s value is stored

pub fn pixel_bytes_mut(&mut self, coords: UVec3) -> Option<&mut [u8]>

Get a mutable reference to the data bytes where a specific pixel’s value is stored

pub fn clear(&mut self, pixel: &[u8])

Clears the content of the image with the given pixel. The image needs to be initialized on the cpu otherwise this is a noop.

This does nothing if the image data is not already initialized

pub fn get_color_at_1d(&self, x: u32) -> Result<Color, TextureAccessError>

Read the color of a specific pixel (1D texture).

See get_color_at for more details.

pub fn get_color_at(&self, x: u32, y: u32) -> Result<Color, TextureAccessError>

Read the color of a specific pixel (2D texture).

This function will find the raw byte data of a specific pixel and decode it into a user-friendly Color struct for you.

Supports many of the common TextureFormats:

• RGBA/BGRA 8-bit unsigned integer, both sRGB and Linear
• 16-bit and 32-bit unsigned integer
• 16-bit and 32-bit float

Be careful: as the data is converted to Color (which uses f32 internally), there may be issues with precision when using non-f32 TextureFormats. If you read a value you previously wrote using set_color_at, it will not match. If you are working with a 32-bit integer TextureFormat, the value will be inaccurate (as f32 does not have enough bits to represent it exactly).

Single channel (R) formats are assumed to represent grayscale, so the value will be copied to all three RGB channels in the resulting Color.

Other TextureFormats are unsupported, such as:

• block-compressed formats
• non-byte-aligned formats like 10-bit
• signed integer formats

pub fn get_color_at_3d( &self, x: u32, y: u32, z: u32, ) -> Result<Color, TextureAccessError>

Read the color of a specific pixel (2D texture with layers or 3D texture).

See get_color_at for more details.

pub fn set_color_at_1d( &mut self, x: u32, color: Color, ) -> Result<(), TextureAccessError>

Change the color of a specific pixel (1D texture).

See set_color_at for more details.

pub fn set_color_at( &mut self, x: u32, y: u32, color: Color, ) -> Result<(), TextureAccessError>

Change the color of a specific pixel (2D texture).

This function will find the raw byte data of a specific pixel and change it according to a Color you provide. The Color struct will be encoded into the Image’s TextureFormat.

Supports many of the common TextureFormats:

• RGBA/BGRA 8-bit unsigned integer, both sRGB and Linear
• 16-bit and 32-bit unsigned integer (with possibly-limited precision, as Color uses f32)
• 16-bit and 32-bit float

Be careful: writing to non-f32 TextureFormats is lossy! The data has to be converted, so if you read it back using get_color_at, the Color you get will not equal the value you used when writing it using this function.

For R and RG formats, only the respective values from the linear RGB Color will be used.

Other TextureFormats are unsupported, such as:

• block-compressed formats
• non-byte-aligned formats like 10-bit
• signed integer formats

pub fn set_color_at_3d( &mut self, x: u32, y: u32, z: u32, color: Color, ) -> Result<(), TextureAccessError>

Change the color of a specific pixel (2D texture with layers or 3D texture).

See set_color_at for more details.
