With this rule, the points in the enclosed pentagon are considered to be inside the shape On the other, in the lower star, which uses FillRuleEVEN_ODD, these same points are considered to be outside the shape and so are not filled:

So how do these rules work For any given point, the first thing to do when determining whether the point is inside or outside the shape is to draw a line through that point, in any direction, but ensuring that it does not pass through a vertex of the shapeWhat happens next depends on which rule is being used The nonzero winding rule, which is the default for JavaFX shapes, is illustrated at the top of Figure 16-22

To determine whether a point is inside or outside the shape according to the nonzero winding rule, do the following: 1 Label each segment of the path with +1 if the pen moves in the positive y direction when drawing it and with -1 if it moves in the negative y direction Segments that are parallel to the y-axis should be assigned the value 0 In Figure 16-22, the figure was drawn in the order A B C D E A; so A B has value 0, B C has value +1 (remembering that y increases as we move down), C D has value -1, D E has value +1, and E A has value -1 2 Initialize a counter to 0 Moving along the line from left to right and starting outside, each time you cross a line, add that line s value to the counterThe values for each of the regions in the shape are shown above the line in Figure 16-22

Regions for which the counter value is 0 are outside the shape, and those that have a nonzero value are insideYou can see that this result tallies with the regions that are actually filled in the star at the top of Figure 16-22 If the shape had been drawn in the opposite direction, the values and accumulated values would have been the same, but with opposite signs Because all that matters is whether the value in a region is 0, the same areas would be filled The even-odd winding rule, shown at the bottom of Figure 16-22, is easier to evaluateTo determine whether a point is inside or outside the shape, draw a line through it as before, initialize a counter to 0 Moving along the line from left to right, each time a segment of the path is crossed, increment the counter by 1 Regions in which the counter is odd are inside the shape and should be filled; those for which the counter is even are outside and should not be filled

The Text Class

The Text class is a shape that draws a text string onto your sceneThe appearance of the text is determined by several variables of the Text object, including the font, which we discuss in the next section Because Text is a shape, you can do everything with it that you can do with any other shape, including setting the stroke and fill variables to control the text color and changing the stroke style if you don t want the individual letters to have solid outlinesAs you ll see in upcoming chapters, you can also apply transformations, such as rotations and scaling, and effects like reflection to your text
