Problems reading animated gif

[Alessandro]

Hi

I tryed to open an animated gif but info.NumberOfImages returns always 1 so I dunno how many frames are stored into it and about the framerate... how do I know the speed of the animation? maybe for animated gif is there a standard I don't know of?

Best regards.

Currrently not possible to know the frame rate. And for gif animated, there is a little problem, try gflLoadBitmap and you'll have a NumberOfImages not 1

When I convert gif to some other format, I got only first frame. How to access (and save) other?

You have GFL_LOAD_PARAMS::ImageWanted

Is there any method to determine value of "Background Color Index" for whole gif and "Disposal Method" and "Delay" fields for pictures in animated gif? Pictures itself reads correctly, but I can't find out how to get this fields

And there is another problem. I'm trying to load animated gif with about a three hundreds of frames. It is not quite big - about 60k, but it loads several seconds. As i call to load evety frame individually, the library, as I suppose, must again and again load and decode file from the beginning. Maybe there is wokaround?

No sorry

The problem is that GFL need to decompress all previous frames...

But adding this fields to GFL_BITMAP structure should not be a problem, isn't it?

Maybe you can register some kind of GFL_BITMAP array[]? Or save a pointer to next picture (offset from the begining of file) in GFL_BITMAP structure and accept it in load bitmap requests?

This is just a few fields, but without them it is almost unreal to load animated gif's. Please...

No, the better way is to add a function to load all bitmap from animated file

I'll be waiting for a new version, thank you.
