Subpaths that start and end on the same point are * still considered unclosed if they do not have a CLOSE segment. * See {@link java.awt.geom.PathIterator#SEG_CLOSE SEG_CLOSE} * for more information on the CLOSE segment. * The three different decorations are: {@link #CAP_BUTT}, * {@link #CAP_ROUND}, and {@link #CAP_SQUARE}. * <dt><i>line joins</i> * <dd>The decoration applied at the intersection of two path segments * and at the intersection of the endpoints of a subpath that is closed * using {@link java.awt.geom.PathIterator#SEG_CLOSE SEG_CLOSE}. * The three different decorations are: {@link #JOIN_BEVEL}, * {@link #JOIN_MITER}, and {@link #JOIN_ROUND}. * <dt><i>miter limit</i> * <dd>The limit to trim a line join that has a JOIN_MITER decoration. * A line join is trimmed when the ratio of miter length to stroke * width is greater than the miterlimit value. The miter length is * the diagonal length of the miter, which is the distance between * the inside corner and the outside corner of the intersection. * The smaller the angle formed by two line segments, the longer * the miter length and the sharper the angle of intersection. The * default miterlimit value of 10.0f causes all angles less than * 11 degrees to be trimmed. Trimming miters converts * the decoration of the line join to bevel. * <dt><i>dash attributes</i> * <dd>The definition of how to make a dash pattern by alternating * between opaque and transparent sections. * </dl> * All attributes that specify measurements and distances controlling * the shape of the returned outline are measured in the same * coordinate system as the original unstroked {@code Shape} * argument. When a {@code Graphics2D} object uses a * {@code Stroke} object to redefine a path during the execution * of one of its {@code draw} methods, the geometry is supplied * in its original form before the {@code Graphics2D} transform * attribute is applied. Therefore, attributes such as the pen width * are interpreted in the user space coordinate system of the * {@code Graphics2D} object and are subject to the scaling and * shearing effects of the user-space-to-device-space transform in that * particular {@code Graphics2D}. * For example, the width of a rendered shape's outline is determined * not only by the width attribute of this {@code BasicStroke}, * but also by the transform attribute of the * {@code Graphics2D} object. Consider this code: * <blockquote><pre>{@code * // sets the Graphics2D object's Transform attribute * g2d.scale(10, 10); * // sets the Graphics2D object's Stroke attribute * g2d.setStroke(new BasicStroke(1.5f)); * }</pre></blockquote> * Assuming there are no other scaling transforms added to the * {@code Graphics2D} object, the resulting line * will be approximately 15 pixels wide. * As the example code demonstrates, a floating-point line * offers better precision, especially when large transforms are * used with a {@code Graphics2D} object. * When a line is diagonal, the exact width depends on how the * rendering pipeline chooses which pixels to fill as it traces the * theoretical widened outline. The choice of which pixels to turn * on is affected by the antialiasing attribute because the * antialiasing rendering pipeline can choose to color * partially-covered pixels. * <p> * For more information on the user space coordinate system and the * rendering process, see the {@code Graphics2D} class comments. * @see Graphics2D * @author Jim Graham */ public class BasicStroke implements Stroke { /** * Joins path segments by extending their outside edges until * they meet. */ @Native public static final int JOIN_MITER = 0; /** * Joins path segments by rounding off the corner at a radius * of half the line width. */ @Native public static final int JOIN_ROUND = 1; /** * Joins path segments by connecting the outer corners of their * wide outlines with a straight segment. */ @Native public static final int JOIN_BEVEL = 2; /** * Ends unclosed subpaths and dash segments with no added * decoration. */ @Native public static final int CAP_BUTT = 0; /** * Ends unclosed subpaths and dash segments with a round * decoration that has a radius equal to half of the width * of the pen. */ @Native public static final int CAP_ROUND = 1; /** * Ends unclosed subpaths and dash segments with a square * projection that extends beyond the end of the segment * to a distance equal to half of the line width. */ @Native public static final int CAP_SQUARE = 2; float width; int join; int cap; float miterlimit; float dash[]; float dash_phase; /** * Constructs a new {@code BasicStroke} with the specified * attributes. * @param width the width of this {@code BasicStroke}.
