ImageMagick on XAMPP is loading and executing but not reading files

My webserver has ImageMagick installed and available (and works correctly), and so I want to make use of it. To do that, I need to run it on my localhost to test code, etc.

I'm using the current version of XAMPP (Version 5.6.14) with Apache/2.4.17 (Win32) and PHP/5.6.16 on Windows 8.1

To install ImageMagick locally, I created this directory off the root:

c:\ImageMagick

Then, from here:

http://windows.php.net/downloads/pecl/deps/

...I downloaded the X86 thread-safe version that would match the DLL (which you have to obtain separately, which mystifies me). The version I downloaded was:

ImageMagick-6.9.1-2-vc11-x86.zip

I unzipped it to C:\ImageMagick and then moved the contents of its "bin" subfolder to C:\ImageMagick, so that everything is in the root of that directory.

I then added C:\ImageMagick to my PATH and verified that it worked by first exectuting "convert" from a command line at a different directory, which then caused the help screen info to display. I then further verified it worked by performing an image resizing from the command line successfully. So far so good.

Then, following the advice culled from other online postings about how to do this, I copied the CORE_RL_.DLL files and the IM_MOD_RL.DLL files from C:\ImageMagick to c:\xampp\apache\bin

I then added this system environment variable:

MAGICK_HOME=c:\imagemagick

The next step is to add php_imagemagick.dll to the php\ext folder in XAMPP, but there's no such DLL among those in the ImageMagick ZIP files/EXEs. To get it, I had to go here:

http://windows.php.net/downloads/pecl/releases/imagick/3.3.0rc2/

...and download:

php_imagick-3.3.0rc2-5.6-ts-vc11-x86.zip

...I then unzipped it to a dedicated "junk" directory and copied the php_imagemagick.dll file it contained to c:\xampp\php\ext

I then edited the php.ini file in c:\xampp\php to include this directive:

extension=php_imagemagick.dll

Now...the moment of truth:

I started XAMPP and checked the PHP_ERROR_LOG, and found no errors. I then ran PhpInfo.php and confirmed that ImageMagick was loaded; here is the screen shot:

PhpInfo.PHP ImageMagick Configuration on my XAMPP

Now, when the following script is run from my live server (DreamHost), it successfully converts the X.JPG image as indicated:

<?php
if (!extension_loaded('imagick')) {
    echo "imagick not installed...";
} else {
    echo "imagick installed...";
}
echo "Start...";
$uploaded_filename = "x.jpg";
$im = new Imagick();
echo "Created object...";
$im->readImage("x.jpg");
echo "Read JPG...";
$im->resizeImage(528, 0, Imagick::FILTER_LANCZOS2SHARP, 1);
$im->stripImage();
$im->writeImage("x_lg.jpg");
$im->clear();
$im->destroy(); 
echo "Done."
?>

However, when I run it from my localhost, it gets as far as creating the $im (ImageMagick object), but it does not proceed to read in the image with the readImage() function ("Created object..." is written to the screen, but nothing beyond that, and no output file is created.)

Any suggestion as to what I may have omitted in my installation?

For full path you can use: 

realpath('images/x.jpg')

instead of 

C:/xampp/htdocs/mysite/images/x.jpg

It turns out that ImageMagick needs the full path to your image files, even if they are in the same directory as the script that is executing ImageMagick on them. It's that simple. Here's how to do it:

Say your images are kept in an "images" folder off the root of your site. On XAMPP localhost, the full path might be:

C:/xampp/htdocs/mysite/images/x.jpg

Thus:

$_SERVER['DOCUMENT_ROOT'] would hold "C:/xampp/htdocs/mysite";
$path_to_your_files = "images/";
$image_file_name = "x.jpg";

Put it all together with this string:

$my_image = $_SERVER['DOCUMENT_ROOT'] . "/" . $path_to_your_files . $image_file_name;

On the live server, the full path might be:

/the_inaccessible_superfolders_of_your_website/mysite.com/images/x.jpg

Thus:

$_SERVER['DOCUMENT_ROOT'] would hold "/the_inaccessible_superfolders_of_your_website/mysite.com"
$path_to_your_files = "images/";
$image_file_name = "x.jpg";

Again, put it all together with this string:

$my_image = $_SERVER['DOCUMENT_ROOT'] . "/" . $path_to_your_files . $image_file_name;

That is what must be fed into new Imagick($my_image); in order for it to work. I hope this helps someone else struggling with this issue.
