如何在 BufferedImage 中隔离红/绿/蓝通道:我有以下代码不起作用:`
public static BufferedImage isolateChannel(BufferedImage image,
EIsolateChannel channel)
{
BufferedImage result=new BufferedImage(image.getWidth(),
image.getHeight(),
image.getType());
int iAlpha=0;
int iRed=0;
int iGreen=0;
int iBlue=0;
int newPixel=0;
for(int i=0; i<image.getWidth(); i++)
{
for(int j=0; j<image.getHeight(); j++)
{
iAlpha=new Color(image.getRGB(i, j)).getAlpha();
iRed=new Color(image.getRGB(i, j)).getRed();
iGreen=new Color(image.getRGB(i, j)).getGreen();
iBlue=new Color(image.getRGB(i, j)).getBlue();
if(channel.equals(EIsolateChannel.ISOLATE_RED_CHANNEL))
{
newPixel=iRed;
}
if(channel.equals(EIsolateChannel.ISOLATE_GREEN_CHANNEL))
{
newPixel=iGreen;
}
if(channel.equals(EIsolateChannel.ISOLATE_BLUE_CHANNEL))
{
newPixel=iBlue;
}
result.setRGB(i,
j,
newPixel);
}
}
return result;
}`
隔离通道是指如果选择红色通道进行隔离,例如,仅显示图片的红色分量!
