Expand description

Creates a blob-image resource with provided parameters.

Must be matched with a DeleteImage at some point to prevent memory leaks.

Fields§

§key: BlobImageKey

A key to identify the blob-image resource.

§descriptor: ImageDescriptor

Properties of the image.

§data: Arc<BlobImageData>

The blob-image’s serialized commands.

§visible_rect: DeviceIntRect

The portion of the plane in the blob-image’s internal coordinate system that is stretched to fill the image display item.

Unlike regular images, blob images are not limited in size. The top-left corner of their internal coordinate system is also not necessary at (0, 0). This means that blob images can be updated to insert/remove content in any direction to support panning and zooming.

§tile_size: TileSize

The blob image’s tile size to apply when rasterizing the blob-image and when storing its rasterized data on the GPU. Applies to both width and heights of the tiles.

All blob images are tiled.
