Are you using the PHP execute(commandline?) instead?
Did you try my PHP version?

imagemagick 6.8.5

Sorry, complete code:



/* Create a new imagick object */
$filename = "test";
$prefix = ".png";

$im = new Imagick();
$im->readimage($filename.$prefix);
$im->setImageFormat('bmp');
$im->posterizeimage(2, false);
$im->setImageColorSpace(imagick::COLORSPACE_GRAY);
$im->setImageType(imagick::IMGTYPE ...

$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?

Hello, I tried the above code and it creates a BW image, but not a truly 1bit BW image file, which is what I need.
The image info needs to say: Colorspace Gray , not RGB.

Anyone?
