Quoting from the docs, "area_prepared", will be called as soon as the pixbuf of the desired has been allocated. You can obtain it by calling gdk_pixbuf_loader_get_pixbuf(). If you want to use it, simply ref it. In addition, no actual information will be passed in yet". From that I would expect that no image data is written until area-updated is called. I wouldn't expect a call to gdk_pixbuf_loader_get_pixbuf() to produce a displayable image in area-prepared.
That's right, but it does get filled in with more data as the loader progresses. Every time my area-updated handler is called I update the display and can see the image progressively load. The problems only started when I tried to scale the image with gdk_pixbuf_loader_set_size().
I still find it strange that you are seeing multiple size-prepared signals. I've only ever seen it emitted once and from the docs I would only expect to see it once.
Strange indeed.
Are you making multiple calls to gdk_pixbuf_loader_write()? I've never tried it. but according to the docs... "This will cause a pixbuf loader to parse the next count bytes of an image."
Yes, this is exactly what I am doing. And again, it worked fine until I tried to scale.
I've never tried to progressively load the image. Your seeing only one area-updated signal does make it sound like progressively loading and scaling the image with gdk_pixbuf_loader_set_size() is not supported.
Yeah, I've resigned myself to this conclusion. It looks like I'll just have to do my own scaling and pass that to the pixbuf loader to accomplish what I need.
