Nuvola tools, Nuvola tools, NUVOLA TOOLs!!

First of all, our apologies: we aren't dead, we were just working for you to create cool stuff ! 
New releases will follow soon thanks to this work, it took many weeks of programming, testing and tweaking to make this program, thank you for reading!

UPDATE: Click here for the Tutorial and help!

Nuvola group is proud to present our new work: a plugin for GIMP, expressly thought for manga/
comics cleaning!

NUVOLA TOOLs offer advanced grayscale cleaning and processing functions for your scans,
automates removal of shadows, dust and toner particles typical of less than perfect prints ,
screentones removal through automated shape and topology recognition and much more!

Kiss espensive PS goodbye and welcome to Nuvola tools: completely free!

Thought not only for manga cleaners but also for artists who scanned their lineart drawings and
anyone wishing to make beautifully clean monochrome scans,

finally a program that automates all those long and tedious operations you had to do manually,
leaving your picture as close as possible to the originals!

Still doubtful? Read the technical specifications:

− Five tools in one box: 1) remove speckles 2) fill white pores on black ink 3) remove specific
shapes, user defined! Road map: 4) damaged lineart regeneration 5) topological

− flexible submenus for topological operations: lets you define and match shapes with
arbitrary precision, fill ratios, distances between elements and sub-modes of operation

− cheat codes for serial operations and scripting

− when properly set for your scanner removes >99.99% of dust particles in just one pass
leaving the original lineart and textures intact

− removes 100% of dark shadows on white background in one pass

− if your blacks and not black but rather a sponge of gray ink and white pores, the whitepores
mode of operation can restore pitch-black art with >99% precision

− specific mode for texture and screentones removal, needs a high resolution scan: above
300DPI ensures 99.9% removal of screentones while leaving the other features intact

− while operating, you may also adjust grayscale levels either automatically or by

− extensive debug and measurement functions: internal operations saved to the shared
memory, you may use debug messages to finely tune your parameters

− extensive set of tuning variables, sliders and knobs 

− Tested on 7000+px high resolution pictures!

− Optimized fuctions rewritten from scratch! For topological measurements there's a 100x
gain in speed from standard libraries like pymorph

− Requires GIMP ( and a linux distro, an installation script to install dependencies is available for debian and ubuntu

You may get the plugin and the installation script *here*

Don't forget to check regularly for updates on this page, Nuvola Tools is actively mantained!

We prepared a couple of samples, they speak for themselves
