Enum webrender_api::ImageData

pub enum ImageData {
    Raw(Arc<Vec<u8>>),
    Blob(Arc<BlobImageData>),
    External(ExternalImageData),
}

Represents the backing store of an arbitrary series of pixels for display by WebRender. This storage can take several forms.

Variants

Raw(Arc<Vec<u8>>)

A simple series of bytes, provided by the embedding and owned by WebRender. The format is stored out-of-band, currently in ImageDescriptor.

Blob(Arc<BlobImageData>)

An series of commands that can be rasterized into an image via an embedding-provided callback.

External(ExternalImageData)

An image owned by the embedding, and referenced by WebRender. This may take the form of a texture or a heap-allocated buffer.

Methods

impl ImageData

pub fn new(bytes: Vec<u8>) -> Self

Mints a new raw ImageData, taking ownership of the bytes.

pub fn new_shared(bytes: Arc<Vec<u8>>) -> Self

Mints a new raw ImageData from Arc-ed bytes.

pub fn new_blob_image(commands: BlobImageData) -> Self

Mints a new Blob ImageData.

pub fn is_blob(&self) -> bool

Returns true if this ImageData represents a blob.

pub fn uses_texture_cache(&self) -> bool

Returns true if this variant of ImageData should go through the texture cache.

Trait Implementations
