Struct nannou::wgpu::ImageReadMapping

pub struct ImageReadMapping { /* fields omitted */ }

A wrapper around a slice of bytes representing an image.

An ImageReadMapping may only be created by reading from a BufferImage returned by a Texture::to_image call.

Implementations

impl ImageReadMapping

pub fn color_type(&self) -> ColorType

Produce the color type of an image, compatible with the image crate.

pub fn size(&self) -> [u32; 2]

The dimensions of the image.

pub fn mapping(&self) -> &BufferReadMapping

The raw image data as a slice of bytes.

pub fn save(&self, path: &Path) -> ImageResult<()>

Saves the buffer to a file at the specified path.

The image format is derived from the file extension.

pub fn save_with_format(
    &self,
    path: &Path,
    format: ImageFormat
) -> ImageResult<()>

Saves the buffer to a file at the specified path.
