Need help loading Animbrushed using datatype system?

What I need to is load one frame, decode the planar graphics to the native video mode (16 or 32bit).

Does any one know how to do it?

Are there any working examples out there, Anim brushes, must have been popular whit game development.

You need to use the animation datatype. Have a look in the datatype folder of the include files in the SDK. Unfortunately I have no good example on how to use it; I was planning to write one after I had finished writing an animation datatype replacement (which would have a new, more powerful API). Unfortunately that's not finished yet.

Just popping in

@LiveForIt

Maybe you can also access it via Picture Datatype using the PDTA_WhichPicture TagItem. It is worh a try.

Not too shy to talk

@Wanderer

That does not work for Anims, only for ILBMs inside a LIST or CAT.

Picture datatype will only read the first image.

Hi Hans can you explain how to use ADTM_LOADFRAME?

No, for image formats which support it, for example GIF (anims) and TIFF, picture.datatype can return all images in it using PDTA_WhichPicture.
For example MultiView supports it, it displays the total number of pictures and the number of the currently displayed one in the window title ("foobar (x/y)") and you can switch between them using the '<' and '>' keys.
