png image data creation using javascript

[Marek Mänd]

Is there any tutorials available how to create a png data totally on the
client side using javascript and then show that image?

Create any image dymanically, or just a fixed one? Does it have to be
png ?

Isn't that an oxymoron?

If you use javascript your MIME type must be html/text
but if you want render an image your MIME type
can't be html/text.

If your using IE you can pull this off, but it's not easy. First of
you'll have to create or edit a PNG file and save your changes to a
..png file. Then you can load it with the AlphaImageLoader filter.

You'll have to know what you're writing though, a PNG file has a
certain file structure you must follow. Here's the official PNG site:

The creation of a new file and writing to the file can be done using
the ADO Stream activexobject:

I've never tried it before, but check it out, maybe it can be done.
good luck.
