RealWorld Paint.COM is an image editor that supports layers, masks and many other advanced features. It includes all the standard drawing tools and image adjustment options as well as support for Photoshop filters (.8bf), layer effects, custom JavaScript filters, image blending, drop shadows, reflections, custom gradients and other features commonly not found in free imaged editors.

Clean user interface
RealWorld Paint.COM can display images using any zoom factor and always shows 100% accurate preview of the drawn shape. Tooltips are displayed throughout the user interface to explain meaning of controls.
After a geometric shape is added to an image, control handles appear and users can further adjust the shape. New points can be added to poly-lines, curves and polygons by dragging a handle of an edge.
RealWorld Paint.COM allows you to edit pictures with layers and assign effects to every layer. A layer can have for example a bevel effect active giving all shapes a 3D look and feel.
The semitransparent rounded rectangle with control handles.
Note the reflection (stripes), shadow, and the blurred rectangle background.

The text layer uses a bevel effect and an azure shadow effect. There is a radial blue->red gradient with center near left lower corner.

Power inside
RealWorld Paint.COM has much hidden power under the hood and harbors features unexpected in a freeware image editor. Many of its drawing tools and image filters are able to do gamma-aware blending and color gradient interpolation, producing correct colors by default.
A strong scripting system allows users to outstandingly extend and customize the functionality of RW Paint.COM using JavaScript. For example the "Create screenshot" command (used to generate the screenshot above) is a scripted function.
Beside the capability to use native plug-ins for virtually everything (filters, tool, fills, windows, codecs, storage, ...), RealWorld Paint.COM is also able to use the vast amount of plug-ins compatible with Adobe Photoshop.
Nifty features
Ordinary applications are boring. RealWorld Paint.COM has a couple of nifty functions, not terribly useful, but fun to use:
Invoke commands using mouse gestures - perform a gesture with right mouse button and something (configure it!) happens. Undoing was never easier.
Vista glass-like effects - draw semitransparent shapes (using "Xxx with effect" tool) and the editor makes your shape look like a window frame on Windows Vista - it blurs background and adds shadow and reflection.
Tool presets - save and quickly restore your favorite gradients, tool settings, or colors.
