Structs

BlobImageDescriptor

Metadata (but not storage) for a blob image.

BlobImageKey

An opaque identifier describing a blob image registered with WebRender. This is used as a handle to reference blob images, and can be used as an image in display items.

BlobImageParams

Input parameters for the BlobImageRasterizer.

BlobImageRequest

A key identifying blob image rasterization work requested from the blob image rasterizer.

ExternalImage

The data that an external client should provide about an external image. For instance, if providing video frames, the application could call wr.render() whenever a new video frame is ready. Note that the UV coords are either normalized or unnormalized depending on the value of normalized_uvs in the corresponding ExternalImageData.

ExternalImageData

Descriptor for external image resources. See ImageData.

ExternalImageId

An arbitrary identifier for an external image provided by the application. It must be a unique identifier for each external image.

ImageDescriptor

Metadata (but not storage) describing an image In WebRender.

ImageDescriptorFlags

Various flags that are part of an image descriptor.

ImageKey

An opaque identifier describing an image registered with WebRender. This is used as a handle to reference images, and is used as the hash map key for the actual image storage in the ResourceCache.

RasterizedBlobImage

Representation of a rasterized blob image. This is obtained by passing BlobImageData to the embedding via the rasterization callback.

SnapshotImageKey

An opaque identifier describing a snapshot image registered with WebRender. This is used as a handle to reference snapshot images, and can be used as an image in display items.

Enums

BlobImageError

Error code for when blob rasterization failed.

ColorDepth

Specifies the color depth of an image. Currently only used for YUV images.

DirtyRect

The possible states of a Dirty rect.

ExternalImageSource

The source for an external image.

ExternalImageType

Storage format identifier for externally-managed images.

ImageBufferKind

Specifies the type of texture target in driver terms.

ImageData

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

ImageFormat

Specifies the format of a series of pixels, in driver terms.

Constants

DEFAULT_TILE_SIZE

The default tile size for blob images and regular images larger than the maximum texture size.

Traits

AsyncBlobImageRasterizer

A group of rasterization requests to execute synchronously on the scene builder thread.

BlobImageHandler

A handler on the render backend that can create rasterizer objects which will be sent to the scene builder thread to execute the rasterization.

BlobImageResources

The resources exposed by the resource cache available for use by the blob rasterizer.

ExternalImageHandler

The interfaces that an application can implement to support providing external image buffers. When the application passes an external image to WR, it should keep that external image life time. People could check the epoch id in RenderNotifier at the client side to make sure that the external image is not used by WR. Then, do the clean up for that external image.

Type Aliases

BlobImageData

Backing store for blob image command streams.

BlobImageResult

Result type for blob raserization.
