Auto Image Size

[Anon]

Hello! I am working on a website where the customer will be uploading their own pics - however, I need the ones they upload to auto scale down if need be.

In other words, I want the height no larger than 100px and the width no larger than 100px. I could hardcode that, but if one they upload is 220 x 100, making 100x100 would of course distort the image.

Basically, it needs to check and if the height or width is more than 100, it needs to scale to ratio the entire image to fit.

Any idea? Is there such a thing?

Thanks!

no... there is no such thing. GEES!

here is the code:

if($new_photo != 'none') {
$array = getimagesize($new_photo);
$im = 0;
if($array[2] == 2) $im = ImageCreateFromJpeg($new_photo);
if($im) {
exec("c:\imagemagick\convert -geometry 100x100 $new_photo $upload_file_path");
} else {
echo "<p align='center'><b>could not upload new photo</b><br />only jpg files are allowed</p>\n";
}
}

this is assuming you have imagemagick installed...

here is how to do it with GDlib:

if($new_photo != 'none') {
$array = getimagesize($new_photo);
$original_width = $array[0];
$original_height = $array[1];
$im = 0;
if($array[2] == 2) {
$im = ImageCreateFromJpeg($new_photo);
} elseif($array[2] == 3) {
$im = ImageCreateFromPng($new_photo);
}
if($im) {
if($original_width > $original_height) {
$thumbnail_height = floor((100 $original_height) / $original_width);
$thumbnail_width = 100;
} else {
$thumbnail_width = floor((100 $original_width) / $original_height);
$thumbnail_height = 100;
}
$thumbnail = imagecreate($thumbnail_width, $thumbnail_height);
imagecopyresized($thumbnail, $im, 0, 0, 0, 0, $thumbnail_width, $thumbnail_height, $original_width, $original_height);
imagejpeg($thumbnail, $file_path_for_upload);

hope that helps.... RTFM!!!!!!!!
