ImageMagick Blues!!!

sol01

I am trying to display a resized image using imagemagick...Here is the code I use:

<?php
$width = "300";

$command = "convert -geometry ".$width." pic.jpg jpeg:-";
$imagedata = $command;

header("Expires: $expired");
header("Content-type: image/jpeg");

echo "$imagedata";
?>

This prints fine, however when I put that into an html page I get the errors already sent error, and spits out the raw garbled code that makes up the image. Anyone have any ideas on how to display the image so that people can actually see it?

just put the location of the script you posted into the SRC part of the IMG tag:

img src="bladebla/image.php"

Wow cool dude thats a real help!!!!

When I have this function in an included file (function.php):

function Thumb($width, $path, $image)
{
$command = "convert -geometry ".$width." $path$image jpeg:-";
$imagedata = $command;
header("Expires: $expired");
header("Content-type: image/jpeg");
echo "$imagedata";
}

my index file reads:

<?php
include ("function.php");
Thumb("100", "images/", "mypic.jpg");

I get the same confused code that makes up the jpeg image. Is it possible to show me the work around for doing this using the function? I tried doing the echo "<img src=\"Thumb(\"100\", \"images/\", \"mypic.jpg\")\">"; but to no avail. TX in advance for the help all.

You have make your index file read:

<?php
echo"<img SRC="http://path.to/image.php">";
?>

and make image.php:
<?php
include ("function.php");
Thumb("100", "images/", "mypic.jpg");
?>

Thats a bit of a behemoth to work with especially if you are parsing variables to the script that tell it what images to display. I guess you could do something like:

<?php
echo"<img SRC="http://path.to/image.php?width=100&path=images/&image=mypic.jpg">";
?>

Any easier ideas???

You could do that yes (provided you fix the qoutes-within-quotes error in that example)

Another option, which will save you oodles of performance, is to create the images permanently on disk, and use a 'normal' IMG tag to link to them. This makes your HTML a lot simpler, and helps very much for performance.

yeah what you mentioned is the ideal, except I want my users to be able to upload any image and it will be held in its origonal size until it needs to be accessed. Then my scripts will detirmine what size it should be in. With this I want to avoid having differant files with the same image.

Not a good idea unless there are a gazillion different sizes that the file should be displayed in.
