Subject Generating images on-the-fly (newbie question)
Date Thu, 10 Oct 2002 00:02:36 GMT
Hi,

	I'd like to generate web-enabled reports (graphs, actually, using
the Perl module GD::Graph) on data from a database using
Apache/mod-perl/Embperl(1.3.4)/DBI/DBD-Oracle.
	I can generate the image and "print" it to a file handle (in
different formats, namely GIF, JPEG, PNG), which will allow me to save it to
a temporary file and then "call" that file in the HTML code using the <img>
tag. However, I'd rather not do that, because of all the complications of
having to deal with temporary files, sessions, clean-up, etc.
	Is there a way, using Embperl, to send the image back to the browser
on-the-fly, that is, without having to save it on a file first? Something
along the lines of (if you'd allow me to write such aberration):

<img src=[- print OUT $gd->png -]>

	I'm aware that the code above isn't HTML, but perhaps it served the
purpose of clarifying what I want to do. Thanks in advance for your help,

---
