Over two years ago I reviewed RealWorld Paint.COM and was impressed. Recently the author released a major update (Version: 2011.1) with a slightly changed name (RealWorld Paint). Once again he sought advice at the DonationCoder forums as well.
This new version has several new features, some of which are listed below that make RealWorld Paint even better and probably even more complete that is required for most users.
The features are: Support layers with styles (individual layers can be filtered with the likes of blur, rotate and more and even worked on with Photoshop tools. This is followed naturally by Photoshop (.psd) format support and a few other formats too. More tools are added that include lasso and liquify. Additional command line support is explained here. An interesting animation tool (Create—>Create Animation) is also new which splits an image into rows and columns which then creates a sort of filmstrip animation with the divided parts of the image.
RealWorld Paint is available in a portable format as well.
