使用JColorChooser的圖像顏色我怎麼可以在Java
圖片使用JColorChooser的這樣
到
圖片2

File input = new File("dprocessing.jpg"); 
image = ImageIO.read(input); 
width = image.getWidth(); 
height = image.getHeight(); 

for(int i=0; i<height; i++){ 
    for(int j=0; j<width; j++){ 
    Color c = new Color(image.getRGB(j, i)); 
    int red = (int)(c.getRed() * 0.299); 
    int green = (int)(c.getGreen() * 0.587); 
    int blue = (int)(c.getBlue() *0.114); 
    Color newColor = new Color(red+green+blue,red+green+blue,red+green+blue); 

    image.setRGB(j,i,newColor.getRGB()); 
    } 
} 

File ouptut = new File("new_Image.jpg"); 
ImageIO.write(image, "jpg", ouptut);

你可以溶膠這已經通過其更改爲這樣：

File input = new File("dprocessing.jpg"); 
    image = ImageIO.read(input); 
    width = image.getWidth(); 
    height = image.getHeight(); 

    for(int i=0; i<height; i++){ 

     for(int j=0; j<width; j++){ 

      Color c = new Color(image.getRGB(j, i)); 
      int red = (int)(c.getRed() * 0.299); 
      int green = (int)(c.getGreen() * 0.587); 
      int blue = (int)(c.getBlue() *0.114); 
      if(c.getRed()>200&&c.getGreen()>200&&c.getBlue()<100){ //this is to make sure that the pixel is some form of yellow. if it is yellow, change it to purple. if it isn't keep the color the same 
       Color newColor = new Color(red,green,blue); //before you were making every field the sum of all 3 colors, I don't know why 
       image.setRGB(j,i,newColor.getRGB()); 
      } 
      else{ 
       image.setRGB(j,i,c.getRGB()); 
      } 

     } 
    } 

    File ouptut = new File("new_Image.jpg"); 
    ImageIO.write(image, "jpg", ouptut);
