Imagick PHP extension not working JPEG XR output

Question

I have a problem with ImageMagick . I searched a lot, but did not find a solution. My problem is outputting a JPEG XR image. I am trying to do this in PHP 7.0/7.1 on a Windows 10 and Linux Debian 9 server.

My code is:

 <?php if (TRUE !== extension_loaded('imagick')) { throw new Exception('Imagick extension is not loaded.'); } $image = new Imagick(); $image->newImage(100, 100, new ImagickPixel('red')); // $image->setImageFormat('jpg'); // <-- It works $image->setImageFormat('jxr'); // <-- Fatal error: Uncaught ImagickException: UnableToOpenModuleFile header("Content-Type: image/" . $image->getImageFormat()); echo $image; $image->destroy(); 

The result of phpinfo () on Windows:

Windows application:

 C:\Users\Andrei>JxrDecApp.exe JPEG XR Decoder Utility Copyright 2013 Microsoft Corporation - All Rights Reserved ... C:\Users\Andrei>JxrEncApp.exe JPEG XR Encoder Utility Copyright 2013 Microsoft Corporation - All Rights Reserved ... 

JxrDecApp.exe and JxrEncApp.exe are available from any directory!

Question:

How to add support for JXR image format?

Answer 1

Good news! The JXR or JPEG Extended Range format is supported by Imagick, but not the way you want. As you are currently trying to access it, this is using a byte array. Compiled by Magick.NET (Imagick.NET library) states the following in a closed Github issue:

The format is supported, but you will need to do some “magic” for it to work. Reading JXR files will only work if you copy the JXRDecApp.exe file to the bin directory and read from a file on a disk with a .jxr extension. Reading from an array of bytes is not supported. It would be nice if the jxrlib project code ( http://jxrlib.codeplex.com ) could be part of ImageMagick. Perhaps I should create a problem for this in the ImageMagick project. You will need to compile JXRDecApp.exe yourself, because there are no binaries available.

Thus, the JXR format is supported, but not in the way you want to apply it. However, the conversion can be done using the command line, as described in StackOverflow here or how.

 convert input.jpg jxr:output.jpg 

It remains to write a script that executes this command to perform the conversion for you. Make sure that you script the script correctly and it inputs and outputs. Good luck

Answer 2

Some PHP packages ship with their Imagick package, rather than using a system package. You can then find what is supported on the command line and what PHP supports as a result.

In the source, PHP directly obtains a list of supported formats from Imagick itself.

If these are not different versions, there may be a hidden abstraction, where jxr is an alias for another parent format with certain options.
