Thanks, but actually that doesn't matter.

I've found the solution for the issue.

I've added this call before cropImage call.
And it has fixed the issue with black&white output. Thanks anyway.

Hi fmw42,

Thanks for the quick reply.

Here is the code snippet that crops a tile from given image:

$img = new Imagick();
$img->readImage($sourcePath);

$iW = $img->getImageWidth ();
$iH = $img->getImageHeight();

$bW = $iW/$xNum;
$bH = $iH/$yNum;

$cropWidth = ($iW - $x*$bW);
$cropWidth ...

In some cases CropImage returns black&white image despite I've provided full color image.

Is this an issue with CropImage method or do I need to use some channels and filters before cropping?
