Hi Dermot,
I have a perl function which converts an image to sepia-tone as follows...
sub sepia
{
my ($image, $color) = @_; # original image object and color
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;
}
All I know is it works with 6.2.3 and later. With 6.0.7 I get an all-black
image.
I'm assuming there is a bug in the Composite() method which has been fixed in
later versions. Can anyone tell me if the "Overlay" compose type is supported
in 6.0.7 ?

If you want the very latest you will need to install from source.
I am not expert in compositing but perhaps you should outline what
the problem is. Are you sure there was a bug with v6.0.7 that was
fixed in 6.2+?
Dp.
