StripePaint is a class for creating striped patterns. These patterns can be used for filling other shapes; in particular, they are excellent for filling the bars of a bar chart.

The basic idea is that you create a stripe by specifying an angle for a line (either as an int for degrees or as a double for radians), along with the size of the tile in the repeated pattern. The class then constructs the tile that is used in the Paint fill. You can specify the foreground color for the line and the background color for the rest of the tile. You can also specify a Stroke to use for the line to give a dotted stripe effect.

For more complex patterns you can use a Paint as the background of the tile instead of a Color. This means you can use a StripePaint as the background to a StripePaint and build up a layered stripe pattern. By careful use of this feature you can create zig-zag patterns, cross-hatches, crosses, and multi-coloured stripes. Finally, you can also create a polka-dot paint effect by setting the dashes of your BasicStroke to have a length of zero and a round cap. The diameter of the dots is the same as the line width. This too, can be used as part of a layered effect - in the example below the background polka-dot layer has larger dots than the foreground layer, allowing us to create a polka-dot effect with concentric circles.

Here are some sample paint patterns generated using StripePaint:

The number labels on the patterns indicate which of the code fragments from the table (below) can be used to generate it:

Pattern	Code to Generate It
1	new StripePaint(0, 10, 2f)
2	StripePaint paint = new StripePaint(-45, 20, 2f); paint.setForeground(Color.green.darker());
3	StripePaint paint = new StripePaint(20, 20, 1f); paint.setForeground(Color.blue);
4	StripePaint paint = new StripePaint(90, 10, 2f); paint.setBackground(Color.yellow); paint.setForeground(Color.red);
5	StripePaint background = new StripePaint(0, 10, 2f); StripePaint paint = new StripePaint(90, 10, 2f); paint.setBackground(background);
6	StripePaint background = new StripePaint(-45, 20, 2f); background.setForeground(Color.green.darker()); StripePaint paint = new StripePaint(45, 20, 2f); paint.setBackground(background); paint.setForeground(Color.green.darker());
7	new StripePaint(45, 20, new BasicStroke(2f, BasicStroke.CAP_ROUND, BasicStroke.JOIN_MITER, 10f, new float[] {10f, 10f}, 0f));
8	StripePaint background = new StripePaint(45, 20, new BasicStroke(2f, BasicStroke.CAP_ROUND, BasicStroke.JOIN_MITER, 10f, new float[] {10f, 10f}, 0f)); StripePaint paint = new StripePaint(-45, 20, new BasicStroke(2f, BasicStroke.CAP_ROUND, BasicStroke.JOIN_MITER, 10f, new float[] {10f, 10f}, 10f)); paint.setBackground(background);
9	StripePaint background = new StripePaint(45, 20, new BasicStroke(2f, BasicStroke.CAP_ROUND, BasicStroke.JOIN_MITER, 10f, new float[] {10f, 10f}, 0f)); StripePaint paint = new StripePaint(-45, 20, new BasicStroke(2f, BasicStroke.CAP_ROUND, BasicStroke.JOIN_MITER, 10f, new float[] {10f, 10f}, 0f)); paint.setBackground(background);
10	StripePaint background = new StripePaint(45, 20, new BasicStroke(2f, BasicStroke.CAP_ROUND, BasicStroke.JOIN_MITER, 10f, new float[] {10f, 10f}, 5f)); StripePaint paint = new StripePaint(-45, 20, new BasicStroke(2f, BasicStroke.CAP_ROUND, BasicStroke.JOIN_MITER, 10f, new float[] {10f, 10f}, 5f)); paint.setBackground(background);
11	StripePaint background = new StripePaint(30, 20, 6f); background.setForeground(Color.blue); StripePaint paint = new StripePaint(30, 20, 3f); paint.setBackground(background); paint.setForeground(Color.red);
12	StripePaint background = new StripePaint(45, 30, new BasicStroke(6f, BasicStroke.CAP_ROUND, BasicStroke.JOIN_ROUND, 5f, new float[] {0f, 30f}, 15f)); background.setForeground(Color.blue); StripePaint paint = new StripePaint(45, 30, new BasicStroke(3f, BasicStroke.CAP_ROUND, BasicStroke.JOIN_ROUND, 5f, new float[] {0f, 30f}, 15f)); paint.setForeground(Color.red); paint.setBackground(background);
