1. Binary to stdout
Howdy all,
I'm programing some cgi on a linux box, trying to
send an image through a cgi script. I got it to
work (by piping the file through cat). I was just
wondering if there wasn't an easier (more system
dependant) way to get a binary file into standard
out.
Thanks in advance,
E.Allen Soard

Allen:
Ever thought of using xpm files ?
Which I think linux can display, you might look at how david
is using them in the win32lib.
Just a thought.

Bernie,
Just tried it, good idea but browsers don't
understand it. What i'm actually trying to do is
code a counter in euphoria. I got it working
using Jeff Fielding's Pipe library and just
kicking the output through 'cat' but that seems
clumsy to me and I was just wondering if there
was another way.

You can send an image to a browser, via STDOUT, if it has the proper mime
content headers to identify itself to the browser.
Without looking it up, I think it goes something like:
puts(1,"Content-type: image/gif\n\n") -- must have two linefeeds.
change the gif to jpeg, if appropriate.

Irv

Irv,
That was the first thing I tried. Because STDOUT
is opened as ascii "w" as opposed to "wb" it
doesn't send the data correctly. Ho-hum...I guess
I'll just have to do things the way I am (or
write a small .so/dll to write binary (is anyone
using a function called "write" may as well use
the 'c' function name.:-p))
later,
Allen

I don't know much about cgi but couldn't you just
save the image on the server as a jpeg and have
the html point to it in a <img src> tag?
I think that's how other counters work.
