Any anti-aliasing filter on image rezise?

[Michel]

Is there a way I can anti-aliasing a gif to be able to get a
hi-quality resizeable backgroundpicture.
When a GIF of JPG is being resized by the browser you get wurse
pictures because it needs a anti-aliasing. Maybe there is some filter
for it...

Or can I write my own subroutine to do this in client-browsers?

Yes, use your favorite graphics program prior to upload.

Maybe there is, but it would be IE only.

No, you cannot. The J(ava)Script engine has not the slightest
idea what an image could be (aside from the Image host object,
but that doesn't provide access to raw image data).

I recommend The GIMP 2. <http://gimp.org/>

I know even better programs to do this, but I need a anti-aliasing on
the client-browser site when the image-size changes on the size of the
browser.
Like a company-logo stretched on the background.

I didn't find a real anti-aliasing here

I would think something like placing the same image slitely moved over
each other and add some opaque to them.

Isn't there any way to build a website that autosizes everything
depending on the browser site. A sort of autosize the complete site
images, tekst, tables, ...

Why is it not enough to upload scaled and anti-aliased images?

Tough luck.

Nothing reliable. Besides, it is one of the most important advantages
of HTML documents *not* to scale the content so that it fits into the
surrounding box, but to extend the box and let the content flow. Why
do you want to give that away? Have you ever read a PDF document in a
small window? You have not, since tiny-scaled characters (and anti-
aliasing) make that impossible if you don't like scrolling.
