BufferedImage bufferedImage = new BufferedImage(width, height, BufferedImage.TYPE_INT_RGB);
BufferedImageGraphicsConfig config = BufferedImageGraphicsConfig.getConfig(bufferedImage);
bufferedImage = config.createCompatibleImage(width, height, Transparency.TRANSLUCENT);方式二
BufferedImage bufferedImage = new BufferedImage(width, height, BufferedImage.TYPE_INT_ARGB);
Graphics2D graphics = bufferedImage.createGraphics();
bufferedImage = graphics.getDeviceConfiguration()
.createCompatibleImage(width, height, Transparency.TRANSLUCENT);方式三
ColorModel cm = ColorModel.getRGBdefault();
WritableRaster wr = cm.createCompatibleWritableRaster(width, height);
BufferedImage bufferedImage = new BufferedImage(cm, wr, cm.isAlphaPremultiplied(), null);画圆形
double centerX=1000/2;
double centerY=1000/2;
double conerX=centerX+100;
double conerY=centerY+100;
Ellipse2D circle=new Ellipse2D.Double();
double radius=Point2D.distance(centerX, centerY, conerX, conerY);
circle.setFrameFromCenter(centerX,centerY,centerX+radius,centerY+radius);
graphics.draw(circle);画正方形
double centerX=1000/2;
double centerY=1000/2;
double conerX=centerX+100;
double conerY=centerY+50;
Rectangle2D rect =new Rectangle2D.Double();
rect.setFrameFromCenter(centerX,centerY,conerX,conerY);画椭圆
double centerX=1000/2;
double centerY=1000/2;
double conerX=centerX+100;
double conerY=centerY+50;
Rectangle2D rect =new Rectangle2D.Double();
rect.setFrameFromCenter(centerX,centerY,conerX,conerY);
Ellipse2D ellipse=new Ellipse2D.Double();
ellipse.setFrame(rect);画线
Line2D line= new Line2D.Double(conerX,conerY,conerX-200,conerY-200);多边形
int px1[]={50,90,10,50};//首末点相重,才能画多边形
int py1[]={10,50,50,10};
int px2[]={140,180,170,180,140,100,110,140};
int py2[]={5,25,35,45,65,35,25,5};
g.setColor(Color.blue);
g.fillPolygon(px1,py1,4);
g.setColor(Color.red);
g.drawPolygon(px2,py2,9);画弧线
g.drawArc(10,40,90,50,0,180);//画圆弧线 BufferedImage inputImage = ImageIO.read(new File("/Users/manager/Desktop/tupian.png"));
Rectangle2D rectangle = new Rectangle(0,0,inputImage.getWidth(),inputImage.getHeight());
TexturePaint tPaint = new TexturePaint(inputImage,rectangle);
BufferedImage bufferedImage = new BufferedImage(100,100,BufferedImage.TYPE_4BYTE_ABGR);
Graphics2D g = bufferedImage.createGraphics();
g.setPaint(tPaint);//填充颜色可以使用g.setColor(new Color(0,204,255))方法替换
//如果需要设置透明度，添加这句代码
g.setComposite(AlphaComposite.getInstance(AlphaComposite.SRC,0.5f));
g.fillPolygon(new int[]{0,100,100,0},new int[]{0,0,100,100},4);
g.dispose();
ImageIO.write(bufferedImage,"png",new File("/Users/manager/Desktop/tupian3.png"));//消除文字锯齿
g2d.setRenderingHint(RenderingHints.KEY_TEXT_ANTIALIASING,RenderingHints.VALUE_TEXT_ANTIALIAS_ON);
//消除画图锯齿
g2d.setRenderingHint(RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_ON);上述内容就是java jwt图形设计是怎样的，你们学到知识或技能了吗？如果还想学到更多技能或者丰富自己的知识储备，欢迎关注亿速云行业资讯频道。
