This error suddenly appeared last Friday. It has been working fine and Now:
Warning: magickwriteimage() expects parameter 1 to be resource, boolean given

Here's the code I use:

// Invoke ImageMagick
$image = NewMagickWand();
MagickReadImage($image, $upload_dir . '/' . $filename);

// Generate the full size image
$image = MagickTransformImage($image, '0x0', '500x500');
MagickWriteImage($image, $upload_dir . '/' . $filename);


Has anyone seen this error? Any help is appreciated!

Check for exceptions. Chances are the image is not being read so subsequent API calls fails since the image resource is not defined.

Thanks for your reply. The resource is defined, then dies for some reason:

// Invoke ImageMagick
$image = NewMagickWand();
MagickReadImage($image, $upload_dir . '/' . $filename);
echo($image); // echoes "Resource#9"
// Generate the full size image
$image = MagickTransformImage($image, '0x0', '500x500'); // dies right here. the resource disappears...
echo($image);// doesn't print out at all
MagickWriteImage($image, $upload_dir . '/' . $filename);

Hmmm, not sure why its dying. We tried a script similar to yours and it worked without complaint. We're using MagickWand for PHP 1.0.7 and ImageMagick 6.6.2-6.

odd...
I'm using the following:

magickWand version: 1.0.7

ImageMagick version: 6.4.2 08/14/08 Q16
