Hello,

I have installed ImageMagick-6.7.1-7 from source. The installation went well, and the logo of the installation example is displayed fine. Then I installed MagickWandForPHP 1.0.8, and the installation also went well.

I tested it with phpinfo, and I'm getting de imagewand box with this information on it:

Code: Select all

magickwand
MagickWand Backend Library	ImageMagick
MagickWand Extension Version 	1.0.8
ImageMagick support 	enabled
ImageMagick version 	ImageMagick 6.7.1-7 2011-08-18 Q16 http://www.imagemagick.org

Then I tried to do a first test of displaying an image with this code:

Code: Select all

$resource = NewMagickWand();
$result = MagickReadImage( $resource, "image.jpg");
header('Content-Type: image/jpeg');
MagickEchoImageBlob( $resource );

But the image never gets printend on the browser. I modified the code to this:

Code: Select all

$resource = NewMagickWand();
$result = MagickReadImage( $resource, "image.jpg");
if ($result) {
	echo "Leyó OK!";
} else {
	echo "error al leer";
}
/*header('Content-Type: image/jpeg');
MagickEchoImageBlob( $resource );*/

And now I'm always getting error on MagickReadImage(). I checked the image.jpg file, and is in the same directory of the php script that I'm running and is readable and writable by all. I can see it without problem with other software, like GIMP. I don't know what else could be generating this problem... can anyone give me a had whit this?

Thanks in advance!

I've solved the problem. I tested the image.jpg with "display image.jpg", to see if I could get some more info... and I got this error:

Code: Select all

display: Wrong JPEG library version: library is 62, caller expects 80

I remembered that I had installed a new "libjpeg". I executed the tests of ImageMagick with "make check" and discovered that some of the tests failed with similar errors, so I uninstalled the last library. I have a PC running Ubuntu 11.04, so I checked in Synaptic PAckage Manager and I already had jpg libraries installed, so I reinstalled ImageMagick and MagicWand again and... problem solved!
