Sadly I found no way to make this precise So I better keep my draw-100-circles approach.

Hi DJ Mike, thank you very much! For anyone else reading this, here's how I made it work for my purpose:

$gradient = 200;
$opaque = 100;

# new imagick object
$img1 = new Imagick();

# some gradients
$img1->newPseudoImage( 10, $gradient, 'gradient:transparent-white' );
$img1->newImage( 10 ...

not, what I needed, but very nice

Here's my solution:

$gradient = new ImagickDraw();
$gradient->setFillColor('white');
for( $i=0; $i<100; $i++)
{
$gr = $innerRadius + $outerRadius/100 * ($i+1);
$gradient->setFillOpacity((1-($i+1)/100)/15);
$gradient->circle( $pos[0], $pos[1], $pos[0]+$gr, $pos[1]+$gr);
}

I thought, the fill ...

Hi Fred, thanks for your answer! Ah, now I see that what you did is not just an example calling existing ImageMagick commands, in fact you extended ImageMagick with a complex script. Well, of course then there can't be a PHP Imagick command for that

Hi, I already found out how to create radial gradients with transparency in PHP Imagick:
$gradient->newPseudoImage( $radius*2, $radius*2, "radial-gradient:white-transparent");
Is there a similar way to realize multigradients like shown on http://www.fmwconcepts.com/imagemagick/multigradient/index ...
