class Style

Style objects are used to encapsulate several pieces of style information to be passed to drawing calls. At the most basic level styles store color information, but they also contain information about line-widths, the type of raster operation to use when rendering, and what pattern to use when drawing lines and outline primatives.

So if you want to draw a green line you could create a style like so:

  
  Style mystyle = Style(Color::GREEN); 

or

  Style mystyle = Style(Color(0,0,255));

However, when you draw your line it will only be one pixel thick. If you want a thicker green line (3 pixels wide) you can do the following:

  Style mystyle = Style(Color::GREEN, 3);

In another situation you might want to create an rubber-banding box by XORing and outline rectangle, so you would create the following style:

  Style mystyle = Style(Color::BLUE, 2, Style::XOR_OP);

Patterns for lines, arcs, and curves are represented using 16 bits.
