imgIRequest* loadImage ( nsIURI URI , nsIURI initialDocumentURL , nsIURI referrerURI , nsILoadGroup loadGroup , imgIDecoderObserver* observer , nsISupports CX , nsLoadFlags loadFlags , nsISupports cacheKey , imgIRequest* request )

Start the load and decode of an image.

Libpr0n does NOT keep a strong ref to the observer; this prevents reference cycles. This means that callers of loadImage should make sure to Cancel() the resulting request before the observer goes away.

Arguments:

URI: the URI to load

initialDocumentURL

referrerURI: the 'referring' URI

loadGroup: Loadgroup to put the image load into

observer: the observer

CX: some random data

loadFlags: Load flags for the request

cacheKey: cache key to use for a load if the original image came from a request that had post data

request: A newly created, unused imgIRequest object or NULL for one to be created for you.

imgIRequest* loadImageWithChannel ( nsIChannel channel , imgIDecoderObserver* observer , nsISupports cx , out nsIStreamListener listener )

Start the load and decode of an image.

Libpr0n does NOT keep a strong ref to the observer; this prevents reference cycles. This means that callers of loadImageWithChannel should make sure to Cancel() the resulting request before the observer goes away.

Arguments:

channel

observer: the observer

cx: some random data

listener

PRBool supportImageWithMimeType ( char* mimeType )

Checks if a decoder for the an image with the given mime type is available

Arguments:

mimeType: The type to find a decoder for

Returns:

true if a decoder is available, false otherwise
