hi,
a simple question: what is the best way to get the size of images ? I
am trying with both nsDOMHTMLImageElement->GetLenght/Width and
imgIContainer->GetLenght|Width and sometimes they get me wrong value
(comparing to the ones firefox gets me - page info) ..

Humm, it seems like the image size is not the same as the size of its
container. e.g.
(...)
imgList->Item(i, getter_AddRefs(node));
nsCOMPtr<nsIDOMHTMLImageElement> img;
img = do_QueryInterface(node);
/// testing imgl* interfaces (from imglib2 - modules/libpr0n/) out
instead of nsIDOMHTMLImage->GetHeight|Width/
nsCOMPtr<nsIImageLoadingContent> imageLoader =
do_QueryInterface(img);
*if* (imageLoader) {
nsCOMPtr<imgIRequest> imgRequest;
rv =
imageLoader->GetRequest(nsIImageLoadingContent::CURRENT_REQUEST,
getter_AddRefs(imgRequest));
*if* (imgRequest) {
nsCOMPtr<imgIContainer> imgContainer;
rv = imgRequest->GetImage(getter_AddRefs(imgContainer));
*if* (imgContainer) {
rv = imgContainer->GetHeight( &heigth);
rv = imgContainer->GetWidth( &width);
}
}
}
(...)
So, before start loading the image, its container (imgContainer) size
might be different from the real image size ? Is it ? Does mozilla
supposes its (container) initial size ?
