You know I was searching for a couple things, I ran across "Turing test".
So I thought, "Okay, interesting name," and I kept looking, it just didn't
ring a bell...
I ran across another link for embedding pictures...
http://www.ckdog.co.uk/php/imgtests/emboss.php
I thought cool! Nice code!
I looked through dictionary dot com for synonyms... merge showed up,
as well as the other words in the "Subject: Concatenate, conjoin, meld,
extract images".
Anyways, I'm taking a look at the emboss items there and I noticed
the server took a little time in delivering the content. It took about one
to two seconds to get the image to me. Don't know if that helps you
at all, but perhaps you know the processor does the processing?
Curious minds want to know. I'm not going to say that I think there's
a 286 handling the delivery, but would you know?
Thanks for "Captcha".
And in reply to Chung, I was thinking along these lines:
Method (1)
1, and only 1, gif to read each character from
(a) letter a is first image inside the gif, so read first image from the big
image, letter 'b' is the second image, so calculate second image location
and read second image from big image, etc.
(b) add the read character to new image,
(c) loop until word is complete,
(d) display new image.
Method (2)
26 images to read each character from
(a) letter 'a' is a.gif, 'b' is b.gif, etc, get appropriate image from correct
file,
(b) add the read character to the new image,
(c) loop until word is complete,
(d) display new image.
My initial thoughts involved it would be easier to create an array and
read the images based upon the file name in the array, and that would
be quicker, but upon reconsidering, loading one big image up and then
processing from the one image seems much quicker (only one disk
access occurs versus 4 disk accesses for 4 character words).
Thanks much.
