Patina is a great way to draw sketches, diagrams, and simple illustrations on your Mac. As a Mac user accustomed to attractive, well-designed software, you'll appreciate Patina's elegant and intuitive interface. And if you've used Windows before, you'll find that Patina not only offers the simplicity you like about Microsoft Paint, but also has some great additional features, including: Continuous shape rotation - objects can be rotated at any angle instead of being limited to specific degrees of rotation Easy tool width adjustment - use the slider to adjust the thickness of shape strokes as well as text font size Intuitive color management - user-configurable favorite colors are prominently displayed and easily selected or edited Transparent image saving - allows you to create an image that has no background color Independently moveable crop frame - easily move and resize crop frame without affecting the image Alpha blending of colors - blend a translucent color with the canvas color to create a new color Anti-aliasing control - turn on and off smooth edges at any time
