[9fans] html5 canvas, go, devdraw

[Francisco J Ballesteros]

Hi,

I'm playing a bit with the html5 canvas, js,  and go servers, and I'm
thinking it would be quite easy to build a devdraw server (an omero like
server would be even easier) so that you only have to run your go program
and it would open a browser as your devdraw device.

Just wondering, anyone playing with such a beast?

cheers

I bet you're streets ahead of anyone else on this one!

You'd be wrong.
I'm just playing :)

But thanks for the compliment.

there is also a gsoc student working on this.  the last bit
is the conversion of random image(6) formats to one canvas will
deal with.

You may be interested in what David Hoskin is doing for one of our
GSoC projects:
	https://bitbucket.org/dhoskin/9webdraw
He's been producing weekly status updates, which you can follow
along with over on the plan9-gsoc google group:
	 http://groups.google.com/group/plan9-gsoc
It's not done, but he's gotten promising results and is still working on
it. Check it out.

It'd be interesting to see how simply something for Omero could be
done, bypassing draw entirely. I really like the model you came up
with there, and wish there was more diversity in implementations.

that's nice, thanks.
I was thinking on using a more abstract interface because, for example,
the canvas has everything needed to provide text frames for something like
acme, and you could write it in go and then make it something that could be
interfaced to programs running on 9.

But a raw 9p devdraw looks cool.
I will take a look.
thanks again.

I will, thanks to all of you for your replies.

Yes, I think that provided what canvas can do, doing something like
an omero viewer should be both fast to write and efficient when running.

Now that I see that drawterms are around the corner, perhaps here already,
I will play with more omero like interfaces.

Glad to be wrong, looking forward to the various outcomes (and
documentation!).
