Create Animated PNG

Hi guys,

I know how to use the ImageIO class to create a PNG image. However, is it possible to create an animated PNG? If yes, how? If no, any third party libraries for download?

Mick Barry

not sure, perhaps have a dig thru:

will let u know if i come across anything.

Mick Barry

does png actually support animated images?
you may need to save as a gif.

Mick Barry

theres a draft extension of the standard to support animation:

don't like your chances of finding a java encoder though, and if you did you then have the problem that most things will only read the first frame anyway.

If you have more than two PNG images, you can use the follownig method to do animation

I cannot use GIF, because I need to display the animation on a mobile phone. J2ME does not support animated GIF.

Looks like I have no luck. :(

Mick Barry

no and i don't think it would support animated png's anyway :(

dr0zaxx :
I have posted two links above with the help of which you can implement animation of PNG files. You just have to display them after specific interval

Yes I cannot display animated PNG directly in J2ME. It is true.

Thanks for the answers anyway.
