heyas
i have the following code to resize an image to any wanted size:
<?
//$image2 = "image.jpg";
function resizeThatPic($image2){
$maxheight = 100;
$maxwidth = 100;
$size = getimagesize ("$image2");
$ratio = ($maxheight/$size[1]);
$constrain_width = ($ratio * $size[0]);
$constrain_height = ($ratio * $size[1]);
if ($constrain_width > $maxwidth){
$mess = ($maxwidth/$size[0]);
$constrain_width = ($ratio * $size[0]);
$constrain_height = ($ratio * $size[1]);
}
$image = imagecreate($constrain_width,$constrain_height);
$colorblue = imagecolorallocate($image, 0, 0, 255);
imagefill($image, 0,0, $colorblue);
if(!($image2 = @imagecreatefromjpeg("$image2"))){
$image = imagecreate($constrain_width,$constrain_height);
$colorwhite = imagecolorallocate($image, 255, 255, 255);
$colorblack = imagecolorallocate($image, 0, 0, 0);
imagefill($image, 0, 0, $colorwhite);
imagestring($image, 4, 10, 10, "Couldn't load image!", $colorblack);
header("Content-type: image/jpeg");
imagejpeg($image);
exit();
}
imagecopyresized($image, $image2 , 0, 0, 0, 0, $constrain_width, $constrain_height, imagesx($image2), imagesy($image2));
header ("Content-type: image/jpeg");
imagejpeg($image);
}
?>
question 1:
I want to use this in an other page:
<?
require ("imagetest.php");
resizeThatPic("image.jpg");
resizeThatPic("image2.jpg");
?>
The problem is that this only shows a resized image.jpg and no image2.jpg at all, why is that? and what can i do about it?
question 2:
Is there a way to save the resized image to another directory on the server?
Thanks in advance :)
