| Hi Dermot,

| my $overlay = $image->Clone; # clone the image to create the top colored
layer
| $overlay->Colorize(fill => $color, opacity=>"100%"); # color the top layer
| $image->Quantize(colorspace => "Gray"); # make the bottom layer grayscale
| $image->Composite(image=>$overlay, compose=>"Overlay"); # overlay the top
layer
| return $image;
| }

image.

later versions. Can anyone tell me if the "Overlay" compose type is supported
in 6.0.7 ?

Their was a bug in Overlay, but that was fixed when I noticed the
problem in creating IM Examples.
Hmmm in version 6.1.6 actually, so yes it is fixed.
The bug as I member would make an image all black except for points with
almost perfect white pixels. Really strange, whcih was why I noticed
and reported it as a bug.
