imagecopyresized()
Hey...I really have two questions:
#1- a Cron Job can be a php file right?
#2- how would i list images in a dir, move and rename them? i know that it has to do with imagecopyresized(), but I looked on php.net and i can't figure out what the attributes of it are supposed to be.
<?php
$height = 200;
$width = 136;
$pic=$HTTP_GET_VARS['pic'];
// the directory name
$handle=opendir('/home/swimtige/public_html/img/pic/');
// initialize variables
$pics=array();
$count=0;
// read directory into pics array
while (($file = readdir($handle))!==false) {
// filter for jpg, gif or png files...
if (substr($file,-4) == \".jpg\" || substr($file,-4) == \".gif\" || substr($file,-4) == \".png\" || substr($file,-4) == \".JPG\" || substr($file,-4) == \".GIF\" || substr($file,-4) == \".PNG\"){
$pics[$count] = $file;
$count++;
// don't forget to close the filter conditions here!
}
}
imagecopyresized(...); //copy to another dir, and then resize to $width and $height
closedir($handle);
?>

If there is no answer on Google, then there is no question.

Have you read through the comments on that function? They seem quite complete. The image is resized, THEN copied, though. It's resized in memory, then stored in a new location.
What have you tried?

if i remember correctly first you need to read in the image, then figure out how much of it you want to resize...
ImageCopyResize($imageSource, $beginingXcoordinate, $beginingYcoordinate, $endingXcoordinate, $endingYcoordinate, $newMaxX, $newMaxY);
meaning that $imageSource is the source you read in, and the rest should be self explanatory.
like i said, i've done this before (but not as a cron job). gimme a sec, i'll post an example
POSIX. because a stable os that doesn't have memory leaks and isn't buggy is always good.

example (reformatting of something i have that works...$pic is the image (full path) and set previously... this gets sent to the browser, you'll have to adapt to something else).
also note that the sizes here are in pixels, so that's putting out a 300 by 300 pixel image
<?php
$src=ImageCreateFromJPEG($pic); # image read in
$width=ImageSx($src); # width (max x coord) of image
$height=ImageSy($src); # height (max y coord) of image
$x=300; # new max x coord
$y=300; # new max y coord
$dst=ImageCreate($x,$y); # create a blank image for resize to send to
ImageCopyResized($dst,$src,0,0,0,0,$x,$y,$width,$height); # resize
header('Content-Type: image/png'); ImagePNG($dst); # send to browser
?>
umm.. update of what i thought (correct this time)
ImageCopyResize($destinationImage, $imageSource, $beginingDestXcoordinate, $beginingDestYcoordinate, $beginingSrcXcoordinate, $beginingSrcYcoordinate, $endingDestXcoordinate, $endingDestYcoordinate, $endingSrcXcoordinate, $endingSrcYcoordinate);
