View source

Summary: Downloads an image from a remote URL and returns the image bytes. This method combines DownloadUrl and LoadImageBytes functionality, using cached values when possible.

Parameters

Name	Type	Description
`blobCache`	[IBlobCache](#	The blob cache to store and retrieve the image data.
`url`	string	The URL to download the image from.
`fetchAlways = false`	bool	A value indicating whether to always fetch the image from the URL, bypassing the cache.
`absoluteExpiration = null`	DateTimeOffset?	An optional expiration date for the cached image data.

Returns: IObservable -- An observable that emits the image bytes.

2. Overload¶

public static IObservable<byte[]> LoadImageBytesFromUrl(this IBlobCache blobCache, Uri url, bool fetchAlways = false, DateTimeOffset? absoluteExpiration = null)

View source

Summary: A combination of DownloadUrl and LoadImageBytes, this method fetches an image from a remote URL (using the cached value if possible) and returns the image bytes.

Parameters

Name	Type	Description
`blobCache`	[IBlobCache](#	The blob cache to load the image from if available.
`url`	Uri	The URL to download.
`fetchAlways = false`	bool	If we should always fetch the image from the URL even if we have one in the blob.
`absoluteExpiration = null`	DateTimeOffset?	An optional expiration date.

Returns: IObservable -- A Future result representing the image bytes.
