I found a sizeing script online that appears to be fairly strait fwd and works 1/2 way.
It seems to be getting stuck when it comes to this section.
/*== check size 0=width, 1=height ==*/
if (($imgsize[0] > 250) || ($imgsize[1] > 200))
{
/*== temp image file -- use "tempnam()" to generate the temp
file name. This is done so if multiple people access the
script at once they won't ruin each other's temp file ==*/
$tmpimg = tempnam("/tmp", "MKUP");
/*== RESIZE PROCESS
1. decompress jpeg image to pnm file (a raw image type)
2. scale pnm image
3. compress pnm file to jpeg image
==*/
/*== Step 1: djpeg decompresses jpeg to pnm ==*/
system("djpeg $imgfile >$tmpimg");
/*== Steps 2&3: scale image using pnmscale and then
pipe into cjpeg to output jpeg file ==*/
system("pnmscale -xy 250 200 $tmpimg | cjpeg -smoo 10 -qual 50 >$imgfile");
/*== remove temp image ==*/
unlink($tmpimg);
}
Any thoughts?
Also if this is a thread that has been discussed already and solved please just include a link.
I have also include the whole script in case that helps as well.
