s:graphicImage and gif

[damianharvey.damianharvey.gmail.com]

s:graphicImage isn't displaying GIFs. The docs say that they are supported by the tag. JPG and PNG are fine.

Seam 2.0.1.CR2, Jboss 4.2.2.GA.

This won't display: <s:graphicImage value="/img/plus_inactive.gif" border="0"/>

This will display: <h:graphicImage url="/img/plus_inactive.gif"/>

Nearest JIRA is http://jira.jboss.org/jira/browse/JBSEAM-1788 but doesn't quite cover display (concerns transformation)

Can anyone confirm this?

Cheers,

Damian.

I have exactly the same problem...

The h:graphicImage tag uses ImageIO (from the javax.imageio) package) for image manipulation.  As far as I recall, ImageIO does not support writing GIFs because of the issue with the unisys patent a few years ago.

After a little Googling I find this link:

Ah, cheers Shane. We'll have to wait for Java 6 then. Unless of course Seam wants to support GIFs by using a library such as one of those listed here. It's a very minor issue for me but maybe someone has a more urgent need?

Maybe the docs should remove reference to supporting GIFs until then?

Cheers,

Damian.

Actually, as s:graphicImage is just an extension of h:graphicImage wouldn't it make sense to just handle GIFs as per h:graphicImage? ie. no transformation.

Either using a library (assuming license compatibility) or updating the docs would be fine by me.

I don't really like s:graphicImage (I like the concept, I don't like the implementation - it needs to be more component orientated I think) so if anyone feels like helping out and giving it some TLC...

has there been any progress on this issue?  It would be really nice to be able to display gifs with s:graphicImage, just like you can with h:graphicImage....

I have tried jboss-seam-2.0.2.CR1, it DO support showing gif!
I think your meaning is that s:graphicImage does not support transforming gif.

You can transform the gif image,then show it.
There are some plugins an tools:
tool:photoshop,
plugin:fmsware-gif.jar.
