MagickWand returning garbage

I tried my first MagickWant script:
Code: Select all
$resource = NewMagickWand();
if (isset($resource)) {
echo "ImageMagick is on";
MagickReadImage( $resource, 'allia.jpg' );
MagickResizeImage( $resource, 100, 100, MW_QuadraticFilter, 1.0 );
header( 'Content-Type: image/gif' );
MagickEchoImageBlob( $resource );
}
else echo "no imagemagick";
and got this. Can someone tell me what I'm doing wrong. Thanks.

You need to set the image format to GIF. By default, since the image is JPEG, MagickWand writes JPEG.

Thanks for the fast reply. First I tried changing Content-Type: image/gif to Content-Type: image/jpeg and that didn't help so I uploaded a gif and changed the code. I garbage changed but I still got garbage.
Code: Select all
$resource = NewMagickWand();
if (isset($resource)) {
echo "ImageMagick is on";
MagickReadImage( $resource, 'gb43j-mrd.gif' );
MagickResizeImage( $resource, 100, 100, MW_QuadraticFilter, 1.0 );
header( 'Content-Type: image/gif' );
MagickEchoImageBlob( $resource );
}

Remove the echo statement so it does not mix with your image. You may also need to set a binary mode if you are running under Windows. We're using ImageMagick 6.4.2 and this command
- php script.php > image.gif
file image.gif
returns a proper GIF image as expected.
