$im = new Imagick(); $im->readimage($filename.$prefix); $im->setImageFormat('bmp'); $im->setImageColorSpace(imagick::COLORSPACE_GRAY); $im->setImageType(imagick::IMGTYPE_BILEVEL); $im->setImageFormat('bmp'); $im->writeimage($filename."BW.bmp"); is there an issue if the base image is PNG?

The image info needs to say: Colorspace Gray , not RGB.

Anyone?
