How can I display an animated GIF image within a B4PPC form? I tried with the HTML Panel library but the animation doesn't seem to animate, it just shows frame 1.

As Erel mentioned in this post the .Net Compact Framework does not support animated gif. :sign0013:

Thanks. I am new to the forum and haven't read much beyond what I need for my programming.

It sounds like we need an animated GIF library to play the frames in these types of image files. It should not be tremendously hard to do as no audio is involved.

Hi CableGuy
Your Flash player/wrapper library is excellent work but it is for the desktop only.:sign0161:

I need something to display animations on the PPC. Everything I write is primarily for the PPC as it is such a useful computer compared to a laptop/PC.

It seems crazy to re-invent the wheel but it looks like I may have to create a program to make bespoke multi-frame animation files and display them. I need to be able to show frame by frame images for a new set of PPC programs I am considering to teach would-be pilots about aviation, airframes, instruments, meterology and so on. Flash animations would have been perfect as they are pretty much designed for that sort of thing.

Maybe you can use the Webbrower library and write dynamicly "<img src='image.gif'/>" on an html file and show it on the Navigator direcly on your program...

How about a library that can return the individual frame images and delays from an animated GIF, specified as a filename, so you can use a Timer to animate them in an Image control?

Curiously I happen to have such a thing running at the moment , but it needs some tidying before it can face the real world.

Hmm, have you looked at the format of an animated GIF and the LZW decompression and image differencing algorithms required to decode the frames? Although I could do it, as I am in this for fun I wouldn't tackle that from scratch as it's a whole s**tload of work. However I found a buggy port of some Java code that I can tidy up and enjoy the fun bit without having to do the heavy lifting.

Ha Ha! Yes, Andrew, I did go online to look at the complexity of LZW decoding and the other complex stuff involved in animated GIF decoding and realised it was way beyond my ability or attention span! But your code for getting the frames and using a timer to dedisplay them is wonderful. Thanks.
