Bufferedimage成圈形状 [英] Bufferedimage into circle shape

问题描述

我有一个来自字节数组的缓冲图像。我如何将图像变成一个圆圈？作物？我不想要一个圆圈，我想让原始图像变成圆形并显示出来。

  def bufferedImage = imgSvc.convertByteArrayToBufferedImage（ crop.image）
  

解决方案

使用下面的代码：

  int width = bufferedImage.getWidth（）; 
 BufferedImage circleBuffer = new BufferedImage（width，width，BufferedImage.TYPE_INT_ARGB）; 
 Graphics2D g2 = circleBuffer.createGraphics（）; 
 g2.setClip（new Ellipse2D.Float（0，0，width，width））; 
 g2.drawImage（bufferedImage，0，0，width，width，null）; 
  

你可以在 circleBuffer

I have a buffered image from byte array. How do I make the image into a circle? Crop? I don't want a circle, I want the orginal image to become circle shape and display

 def bufferedImage = imgSvc.convertByteArrayToBufferedImage(crop.image)

解决方案

If bufferedImage is squared, then with this code :

int width = bufferedImage.getWidth();
BufferedImage circleBuffer = new BufferedImage(width, width, BufferedImage.TYPE_INT_ARGB);
Graphics2D g2 = circleBuffer.createGraphics();
g2.setClip(new Ellipse2D.Float(0, 0, width, width));
g2.drawImage(bufferedImage, 0, 0, width, width, null);

you get a circular cropped image in circleBuffer
