Greeings Monks,

I've been working with some images recently using imagemagick. I started by creating the desired image with the command line tools, but the final objective is to avoid forking off processes, so I would like to be able to use Image::Magick to replecate my steps. This is where I run into trouble.

A brief synopsis of the commands I've run (escape for your shell as needed):

convert ( imgbase*.gif -colorspace Gray -colors 2 -negate ) -colorize +$color -negate -transparent white outimg%02d.gif convert -background white outimg01.gif outimg02.gif outimg03.gif $etc +-flatten outcomp.gif

And the code that from what I've gleaned from the documentation should do the same thing.

my $image; print "Creating composite...\n"; my @imgfiles = glob("img*.gif"); my $compos = Image::Magick->new(size=>'3200x1324'); foreach my $img (reverse @imgfiles) { print "\t Compositing image $img... "; $image = Image::Magick->new(); $image->Read($img); $image->Quantize(colors=>2,colorspace=>"Gray"); $image->Negate(); $image->Colorize(fill=>"rgb(".(pop @colors).")"); $image->Negate(); $image->Transparent(color=>"white"); push @$compos,$image; undef $image; print "composed.\n"; } $compos->Flatten(); $compos->Write('outcomp.gif');

The docs seem kindof sparse and obstruse to me, so if there are undocumented caveats or other things I should know please light the darkness monks.
