Re: New Image Features

2001-05-20 Thread Scott Rossi

Has anyone built a stack (or written out) how to take advantage of this
stuff yet?


  The imageData, maskData, and alphaData properties can be used to set
  the pixels that an image object displays.  The imageData is a
  sequence of 32 bit binary values, with 8 bits each for red, green,
  and blue.  The maskData is sequence of 8 bit values, which 0 being
  transparent and all other values being opaque.  The alphaData
  property is a sequence of 8 bit values with variable transparency
  from 0 (totally transparent) to 255 (totally opaque).

Swamaji,

Everyone is a novice in some area!  Let us not hesitate to speak
here in the assembled of the learned even if we don't know what
we are talking about.

That said, I might be completely wrong, but I don't think HOL
is paying any attention to referrers.  EG, in that formmail.pl
script we used - the widely known one from Matt's archive -
there is code that checks the referrer.  We just took it out.  .
I had people calling that script from all kinds of places,
Calif to NY - no problemo.

Since we will be the authors of the cgi programs, we don't have
to put referrer checks in.  HOL won't be paying attention to
where our programs are being called from.  That's my possibly
undereducated view point.  IE, nothing to worry about.
Unless they have changed something.

I think Andu and I agree, there is no more threat.  The issue
is convincing HOL.

It's possible when he is talking about bandwith he is referring
to cpu cycles and indicating MC may take more of them to do its
processing - I don't want to put words in his mouth though.
I think that would be a moot point in your case, with such
comparitively small scripts.  If it actually did become an
issue on HOL - meaning - if they notice our programs bogging
their server down - we could consider rewriting the pig jobs
(oops, no offense to pigs intended, just industry slang) in a
compiled language.  Now, compiled programs, there's where HOL
should really be scared if they dont have their security down
pat, but I think they do.  However, there is nothing to stop
us from writing C for Sun O/S, compiling and installing it on
their server.  They are not preventing this, so no reason they
should worry about MC, IMHO.

It's possible he means bandwidth in terms of number bytes uploaded
per time frame - your site already gets a lot of traffic and I
don't believe they are charging for useage, right?   So that is
a non issue too.

Sadhu
