Modules§

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.
