Topic awaiting preservation: rotate images script

Javascript or dhtml . . each one can accomplish this task- any preferences I should know about which could be the deciding factor? I guess speed and browser compatability are the main concerns. . .

Thanks.
Chris

DHTML is the combination of JavaScript, CSS and HTML. So this will not really be a decision between JavaScript and DHTML, because DHTML mainly IS JavaScript. If I did not understand this question, please tell me.

Koenie

yes- thanks.

What?

yes-thanks? - Is that an answer to Koeine's question?


In any event, you can't rotate an image using Javascript period. You can do it in IE PC using active X scripting but that's something completly different.

I was wondering the same thing.

You can simulate rotation in Javascript/dhtml by swapping in multiple images. I do that with that cursor chaser tute I did for the GN. CRO8, take a look at all the images I saved out to do that in the tute.

I also did a fun little page with a Babylon 5 ship here.

Ay! I remember finding that B5 demo on your site a while back. That's way cool. Reminds me of those faithfull engineering school years I lost to playing starcraft. Heh.

Yes!!! I once considered doing some sort of StarCraftesque dhtml thingy but then I realized just how much work it would be and went on to other things But maybe I'll revisit that idea one of these days.

Drac - I don't think Koenie asked a question =)

CRO8 may be talking about a script that rotates through multiple images, like max's random sig script, or something like that. He might not be talking about physical rotation.

Only CRO8 knows which it is. Both methods are quite well supported around here so I think we've got him covered.

ahhh. When I said "rotate" I did not mean physical rotation- but random image swapping- as Slime stated. Sorry I should have have been more clear!

Thanks.

Assumptions are the mother of all screwups. My bad.

For a scrpt like that, it really depends on what your using it for. Javascript for client side stuff, but if you want to link to a random image from an external source (like a sig rotating script) then a PHP or CGI script of some kind would be the way to go.

CRO8: I would imagine that you can do it but only in IE using their transformations/filters (I've not checked but something like matrix rings a bell) - which is what Dracusis meant when he refered to their Active-X stuff .

[edit: yep the Matrix filter looks like the right one:
http://msdn.microsoft.com/workshop/author/filter/reference/filters/matrix.asp

but have a look here:
www.scottandrew.com/dhtml/docs/rotator.html

which does give the illusion of an object rotating - which is what Slime was talking about. Seems like a lot of effort unless you used server-side scripting to create a rotated version of your image which was then fed to the DHTML!!]

However, it may be a task more suited to Flash or animated gifs.

[edit2: And bugs I still love that Minbari chaser!!]

[edit3: Now I've stopped playing with Bugs' cursor chaser I should get back to CRO8's actual questions - this is perfectly possible and it is how the random title graphic thingy works at the GN - all the images are held in an array and then a touch of randmoness allows us to grab the right graphic - have a peak at the script in action and if you have trouble reverse engineering the code for your needs let us know ]
