JB,
Here's the solution which works for me. I know it seems a bit
bizarre. It took many attempts to figure out how to get it to work
reliably. But this works all the time.

---------------------------
-- buffer has the incoming data stream
put buffer into temp
put empty into pictfile
put offset("image/jpeg",temp) into xx
if xx <> 0 then
put xx+14 into xx
put char xx to (the length of temp) of temp into pictdata
put char 1 to xx-1 of temp into tdata
repeat with i = the length of pictdata down to 1
if chartonum(char i of pictdata) is 0 then
put i into holdit
exit repeat
end if
end repeat
delete char (holdit+1) to the length of pictdata of pictdata
put "binfile:TempPict_" & the milliseconds & ".jpg" into PictFile
-- these next steps are critical. It doesn't work otherwise.
Field "temp2" is just an empty text field on the cgi stack
put pictdata into url PictFile
put url PictFile into pictdata
put pictdata into fld "temp2"
put fld "temp2" into url PictFile
The file PictFile will now be a regular jpeg file you can read and
manipulate as you would any jpeg file

Hi guys,
Has anyone already tried to parse data from a multipart/form-data html
form
(that contains a type=file element) with Rev cgi ?
I've done it successfully in the past with ascii data, but now I'm
trying to post
jpeg data along with other parameters (height & with of the pic,
session
#...)
in the same form, and obviously the jpeg binary data get corrupted in
the process...
Any idea ? Or will I have to use php again (sigh) ?
Best,
JB
