Converting image to webp with ImageMagick

[dal77]

I am trying to to convert a jpg image to webp in a php script that uses Imagick, but it fails to recognise the webp format. I have installed the latest version of ImageMagick from source, libwebp-dev and php-imagick. I cannot figure out what I am missing.

Code: Select all

$im = new Imagick('$src');
$im->resizeImage($width,$height,Imagick::FILTER_CATROM , 1,TRUE );
$im->setImageFormat( "webp" );

PHP Fatal error:  Uncaught ImagickException: Unable to set image format in /ImageMagick-7.0.3-4/test.php:15
Stack trace:
#0 /ImageMagick-7.0.3-4/test.php(15): Imagick->setimageformat('webp')
#1 {main}

Code: Select all

convert -version

I have noted that WEBP is missing from the list of supported formats, but I don't understand why.

Imagick compiled with ImageMagick version => ImageMagick 6.8.9-9

As you are using Imagick, the question is whether the ImageMagick library it uses has been built with webp.

You have another installatation, 7.0.3-4 with webp, but that isn't relevant.
