Centos 6/RHEL install Cinepaint

According to Robin Rowe at the Greater London Linux Users Group in Dec 2012, Linux is the #1 operating system for feature animation and visual effects. It is used by all the major studios for their film making, and Cinepaint is the most popular image editing software in the industry after Photoshop.

Now based on GTK as opposed to the earlier FLTK, release's for Linux, Mac and Windows see Cinepaint solidify it's place in the Open Source community whilst retaining its individual idiosyncratic persona.

CinePaint was created by using an existing open source paint app which had been abandoned by the developers, cleverly replacing its old low fidelity 8-bit core with an image engine that handles 8-bit, 16-bit and 32-bit high dynamic range channels. Some of the features include
  • Support for 8-bit, 16-bit and 32-bit color channels of deep paint.
  • High fidelity image file types such as DPX, OpenEXR and 16-bit TIFF. These files can’t be opened in ordinary 8-bit image applications without crushing them.
  • High Dynamic Range. HDR images can go brighter than white. Ordinary images can’t be brighter than a white sheet of paper (0=black, 1.0=white).
  • Gallery-quality printing. B&W photographs have only one color channel and degrade quickly when manipulated as 8-bit images.CinePaint has higher fidelity and offers a 16-bit printing path to the print-head using GutenPrint.
  • Color Management System. CinePaint uses LittleCMS.
  • Flipbook. Movie playback of short sequences of images in RAM.
  • Innovation. CinePaint offers features that go beyond ordinary painting programs.
  • Open Source. With various OSS licenses, as it uses code from various sources, including GPL, LGPL, BSD, and MPL.
  • Free.
With a large selection of tools for deep paint manipulation and image processing it is quite a useful program and one of the better ones you will find for use on Linux.
CinePaint is used for motion picture frame-by-frame retouching, dirt removal, wire rig removal, render repair, background plates, and 3d model textures. 

It has been deployed on a number of feature films, including The Last Samurai, in which it was used to add the flying arrows. It's also being used by pro photographers who need better color fidelity than is available in other tools.

Installation on Centos is simple thanks again to the guys at Nux Dextop, with a simple binary package download, the nux-dextop version is currently 0.25.0.

To obtain nux-dextop first install wget if not installed.

$ sudo yum -y install wget                           

$ wget


$ wget

for the repo pack       

$ sudo rpm -Uvh nux-dextop-release-0-1.el6.nux.noarch.rpm

to install it.

$ sudo vi /etc/yum.repos.d/nux-dextop.repo   

set 'enabled' to '0'

$ sudo yum -y --enablerepo=nux-dextop install cinepaint

Setting up Install Process
Package cinepaint-0.25.0-0.1.el6.nux.i686 already installed and latest version
Nothing to do

I already have it but you should get 2 packages and be done.

Simply run it with

$ cinepaint

See Fluxbox key bindings if you are using Fluxbox.

Cinepaint is a pretty useful addition to your Centos/RHEL box
