Thanks for your replay.
The C-programing article was interesting. However; my problem was much simpler then I
first thought. Here is the code I've written:
<code>
//$imgurl is the uploaded file
//$name is the new name for the image
//$cor_x is the x coordinate in the original image where the thumb should start
//$cor_y is the y coordinate...
//$orig_w is the original width of the area that should be converted to the thumb.
//$orig_h is the original height...
function jpgUploadSmall($imgurl, $name, $cor_x, $cor_y, $orig_w, $orig_h) {
$thmb_w = 50;
$thmb_h = 50;
$path="../../plantis/img/sort/";
$fileName = $name.".jpg";
$origImg = imagecreatefromjpeg($imgurl["tmp_name"]) or die("Could not create
image");
$tmpImgA = imagecreatetruecolor($orig_w, $orig_h);
$tmpImgB=imagecreatetruecolor($thmb_w,$thmb_h);
imagecopy($tmpImgA, $origImg, 0, 0, $cor_x, $cor_y, $orig_w, $orig_h);
imagecopyresampled($tmpImgB,$tmpImgA,0,0,0,0,$thmb_w,$thmb_h, $orig_w, $orig_h);
imagejpeg($tmpImgB,$path.$fileName) or die("Could not write image");
imagedestroy($origImg);
imagedestroy($tmpImgA);
imagedestroy($tmpImgB);
return $fileName;
}
</code>

There is an extension in PECL (iisfunc) that hnadles this directly. It
works with both PHP4 and PHP5

Thank you for your reply... I had seen only php_iisfunc.dll very quickly
from my googling, but no info on it. Now that I realise what it is, it
will save me quite a bit of trouble (and I'll get by, I hope, on the
method declarations/source).
Thank you for developing the extension and more for letting me know about it.
Happily, A quick test (<?php echo( iis_stopservice('w3svc') ); ?>) under
php 4.3.4 worked very well.
Unfortunatly, under php5 (upon startup) I get the message "The procedure
entry point zend_hash_index_update_or_next_insert could not be located in
the dynamic link library php4ts.dll" (which then gives the message that
php_iisfunct.dll could not be loaded).
The server has the same configuration for both php4 and php5, php4ts.dll
in c:\winnt is php5's (beta3 version).
For both versions, I use php from the command line.
Is there something I'm missing out on?
Thanks in advance,
Andrew
