Rainbow Painter (for Mac OS X) 3.1.0

Rainbow Painter (for Mac OS X) 3.1.0 is designed as a professional tool that comes with lots of exciting features and technologies. It supports 32-bit float/channel HDR, which permits adjustments to be made back and forth without losing quality.

There is also a revolutionary new pattern editing mode, which puts the old technique of using a so called Offset Filter to achieve seamless tiles to shame.

When switching on the repeat function in Rainbow Painter (horizontally, vertically or both), not only will the image be displayed repeatedly, but all effects support this mode and brush strokes will continue over the edges when drawing.

Major Features:

1. Layers
   
   • Today, the graphics layers have different blend modes and other settings.
   • HDR & Floating Point Precision
   • Conventional programs use 8 bits per channel (red, green, blue, alpha), an integer value of 0-255, which is only 256 possible levels.
   • Rainbow Painter uses 128 bits per pixel and each color component is a 32-bit floating point value with literally billions of possible levels!
   • Even if you didn't grasp everything about the bits, components and floating points above, you only need to know one thing:
   • Having billions of levels gives you much more precision than just having 256!
   • In addition to this higher precision, all of Rainbow Painter's tools, effects and operations support
2. HDR (High Dynamic Range). This gives you even more precision, since they actually work beyond what is visible to the human eye.
   What's the point of this, you ask. Well, here's a concrete example:
   
   • Suppose you use a tool or an effect to, for instance, drastically increase the brightness in an image.
   • You continue working on your picture, only to later decide that you want to lower the brightness in some areas.
   • In a conventional program, these areas will now look posterized and ugly.
   • In Rainbow Painter, on the other hand, all that super precision has worked its magic and the picture is as crisp and vibrant as ever!
   • Also, photographers can import their HDR images and retouch them in Rainbow Painter without losing their high dynamic range.
3. Tools
   
   • Rainbow Painter offers lots of different tools, ranging from basic tools like pen and eraser to oil, airbrush and more.
   • When you draw or paint in this program you will always get the best result, thanks to extra precise anti-aliasing (where both the brush and the actual brush strokes are anti-aliased)
4. Effects
   
   • You will find normal everyday effects like Brightness and Motion Blur, as well as some fancy ones like Rainbow Painter's unique Splash effects.
5. Revolutionary Pattern Editing
   
   • View and edit seamless textures and patterns in true WYSIWYG (What-You-See-Is-What-You-Get) style.
   • Just switch on the repeat function (horizontally, vertically or both) and start working!
   • It's like having your artwork on a wallpaper, in a repeating pattern.
   • You can apply effects or paint/draw anywhere on this wallpaper and see the true results immediately!
6. Windows & Dialogs
   
   • Virtually all windows and dialogs in Rainbow Painter can be transformed into re-usable permanent windows, by clicking in the lower left-hand corner of the window, marking it with a capital 'P'.
   • A permanent window can be moved around and will, as the name implies, stay open until manually closed instead of automatically closing after one use.
   • Also in the lower-left hand corner, you will find a button with a '-' sign on it.
   • Clicking on this button will make the window significantly smaller, but still fully functional! Clicking again on the button (which now has a '+' sign on it instead) returns the window to normal size.

Enhancements: Various improvements.

Requirements: OS X 10.4 or later
