Thank you for this wonderful class! I just upgraded to version 2 but cant get the example work. I put the two files, and an image called test.jpg, in the same folder, and I changed the saveImage-location to the same folder. But the only thing that appears is :
“Problem converting image! Make sure you are Loading it.
Cannot Save File: save.jpg NO DATA IN OUTPUTCould not save Image!
Output Width: 800px
Output Height: 600px ”

Suggestions?

Thanks

However, this 1.3 class is now superseded by a PHP 5.2+ version, Image Snapshot v2.0. Although it works in the same way, it works with less code and more readability. The class methods have changed slightly, but should be self explanatory.

You can download it here:
blog.jc21.com/wp-content/code/image_snapshot_v2.0.zip

include(’snapshot.class.php’);

$myimage = new ImageSnapshot;
$myimage->ImageContents = ‘test.jpg’;
$myimage->Width = 307;
$myimage->Height = 161;
$myimage->Resize = true; //if false, snapshot takes a portion from the unsized image.
$myimage->ResizeScale = 100;
$myimage->Position = ‘center’;
$myimage->Compression = 80;

if ($myimage->ProcessImage() !== false) {
$img = $myimage->GetImageContents();
} else {
echo $myimage->Err;
}

//saving to a filename
if ($myimage->SaveImageAs(‘temp.jpg’)) {
echo ‘ReturnedWidth . ‘px;height:’ . $myimage->ReturnedHeight . ‘px;border:1px solid #f00;”>ReturnedWidth . ‘” height=”‘ . $myimage->ReturnedHeight . ‘” alt=”" />’;
} else {
echo $myimage->Err;
}

I would analyse any log files and if there’s no problem there, update your PHP GD DLL.

Second, I’d like to tell you what I’ve changed in order to work nicer with pictures which have only one dimension bigger than the desired result picture (only width or height, not both of them), maybe this is something who interests others too:

1. At line 247, I’ve changed the “AND” comparison, with an “OR”:

if ($image_width > $this->Width || $image_height > $this->Height)

2. I’ve changed the maxwidth / maxheight calculation in the if at line 254:

if ($w_ratio < $h_ratio) {
$maxheight = ceil($image_height * $w_ratio); $maxwidth = ceil($image_width * $w_ratio);
} else {
$maxwidth = ceil($image_width * $h_ratio);
$maxheight = ceil($image_height * $h_ratio);
}

PHP4 and PHP5 versions. This class has no documentation, you’ll have to figure out the class methods yourself :) enjoy

Loving this class. However, i cannot figure out how to just resize the image without cropping. is it possible? Trying to make it 100px by 100px, but it crops.

Thanks

Love the class. I’m trying to integrate it into the MG2 photo gallery. I can get it to create a thumbnail, no problem, but MG2 supports multiple uploads and when I try to upload 2 or more images at the same time, I get an error:

Fatal error: Cannot redeclare class imagesnapshot in /usr/local/psa/home/vhosts/digitalexpression.ca/httpdocs/clients/funskate/gallery3/includes/snapshot.class.php on line 86

Can you point out how to get around this? Any help would be very appreciated.

You should add the option to resize by pixels instead of just by percentage.
