Imagick::getImageRedPrimary
getImageRegion has the same side effect that was mentioned for operations that change the crop of the image -- the new image preserves the old canvas and positioning info. For example, using annotateImage on the new image will interpret the positioning arguments relative to the old image. To correct it, reset this info with setImagePage.
<?php
$im->setImagePage(0, 0, 0, 0);
?>
