Part of the image is missing after resize new!
by Mike, 13 years, 4 months ago
I have a simple function for resizing images. After I resize the image, part of the image is always missing.
I'm pretty sure the resize worked fine when I first started playing with the upload class, but after embedding it in to my PHP code, the images aren't displaying properly anymore.

Here's my resizeImage function:

public function resizeImage($width, $height, $filepath) {
    $config = Config::getInstance();
    
    $handle = new upload($filepath);
    $handle->image_resize = true;
    $handle->image_x = $width;
    $handle->image_y = $height;

    $handle->process($config->getValue('uploadedfile_dir'));
    if (!$handle->processed) {
        echo "Error: " . $handle->error;
        print_r($handle->log);
    }

    $filepath = $handle->file_dst_pathname;
    $handle->clean();

    return $filepath;
}

Original image: http://tinypic.com/r/28m0osn/7
Resized image: http://tinypic.com/view.php?pic=2nrmzjn&s=7

I am not sure what is happening. Is it reproducible? Does it do that with all images? Does it do it on different servers?Reply

Sorry for the delay.

No, not every image. Some make it through just fine, some images have 50% of the image missing, other have 80%.
I'm not really sure what the pattern is.

I'll try testing it on another server and see what happens.Reply

Tested this on another Ubuntu server running PHP 5.3.5.
The original server is running PHP 5.3.2.

Picking random images from the internet, some work and some don't. Weird...Reply

Just did a lot of troubleshooting on this and found that my issue had to do with how i was storing the file in MySQL. I was using BLOB instead of LONGBLOB, so my images were being cut off.

No issues with the Upload.class at all! Whew :)Reply
