Thanks to both of you.

I gave it a little twist. I converted the image to png (not gif) and used the last command with it.
That did it for me.

I want to reduce the number of colors of a jpg image to 16, with the following command:

convert -depth -colors 16 image.jpg image-16.jpg

When I count the colors in the image it's about 24000.

What is the correct convert syntax to get a color count of 16?

I've tried the command line and it works fine. By the way, it's the alternative I use right now. I've checked both sites. For PerlMagick, I have the latest version installed.

After this update, my Perl script just dies, without any errors, at the following command: $image->Annotate(font=>'arial.ttf', pointsize=>10, gravity=>'center', fill=>'black', text=>$title); This has worked perfectly before. And even the 'Hello World ...
