how to convert array or coordinates to image

[Eadmund@letterbee.com]

Hi,

Pretty sure this is a non starter, but does anyone know how to convert
an array of x-y coordinates, plotting a shape, in to a image (BMP, GIFF
etc) in javascript?

Regards

Can't be done in javascript (at least not for all web browsers), you
won't be able to create an image file.

Check out the <canvastag. It's supported in firefox and opera and
there are hacks which get it to work in IE. It's the wave of the future
and should be pretty standard to most working browsers in 2008.

You could, of course, write the logic to encode the shape as an array of
byte-sized numbers matching the desired content of the BMP file (and
similarly with more effort for other formats). From that, generate,
still using javascript, a DEBUG script which will create that file.
Write it to a new window, and write instructions to Select All on that
window, copy to clipboard, and paste into DEBUG.

It's a good idea to read the newsgroup and its FAQ. See below.
