Why doesn’t the page output the recolored image? Security, server load, tuning (fuzz factor may need adjusting), time constraints, architecture. It is unlikely the tool will ever execute the commands to recolor the images, however, it will probably be implemented with an SOA architecture, which would allow more efficient execution.

Can I have a copy of the code? Not yet. See reasons posted for robots.design code, in this blog.

My image didn’t get colored the way I would have liked. Development continues.

Why are the uploaded images resized to thumbnails? To limit the number of colors involved. This greatly speeds processing.

Some of the convert commands look redundant or even as if they will collide Development continues.

What is ImageMagick? http://imagemagick.org

Will batch processing be implemented in the future? Probably. See earlier note about SOA.
