I had problems running ImageMagick on Windows XP too. I also go this
error and found that the problem was in the php when it called the
convert EXE. It was using the wrong quoting character. I am using
1.3.7, and found that I had to change Image.php
in function: function createThumb( $width ):
originally:
$cmd = $wgImageMagickConvertCommand .
" -quality 85 -background white -geometry {$width} ".
escapeshellarg($this->imagePath) . " " .
escapeshellarg($thumbPath);
to:
$cmd = $wgImageMagickConvertCommand .
" -quality 85 -background white -geometry {$width} ".
"\"$this->imagePath\" \"$thumbPath\"";
I'd give a diff, but I also later changed image.php to support a limited
image gallery I was working on, which is unrelated to this fix. Try
this and let me know if it works.
