图像转换会产生红色图像吗？

Question

我正在尝试通过水平翻转图像并调整其大小来变换图像。问题在于，完成转换后，图片的颜色都变得很怪异，就变成了这种红色调。我想我在某处读到它可能是AWT库中的某些错误，但我不确定吗？

这里是代码：

import java.awt.Graphics2D;
import java.awt.geom.AffineTransform;
import java.awt.image.AffineTransformOp;
import java.awt.image.BufferedImage;
import java.io.File;
import java.io.IOException;
import javax.imageio.ImageIO;

public class LocalImageSizeFlip {

public static void main(String[] args) {
    BufferedImage img = null;

    try {
        img = ImageIO.read(new File("C:\\picture.jpg"));
        AffineTransform tx = AffineTransform.getScaleInstance(1, -1);
        tx.translate(0, -img.getHeight(null));
        AffineTransformOp op = new AffineTransformOp(tx, AffineTransformOp.TYPE_NEAREST_NEIGHBOR);
        img = op.filter(img, null);
        img = resize(img, 100, 75);
        File newFile = new File("newPicture.jpg");
        ImageIO.write(img, "JPEG", newFile);
    } catch (IOException e) {
        e.printStackTrace();
    }
}

private static BufferedImage resize(BufferedImage image, int width, int height) {
    BufferedImage resizedImage = new BufferedImage(width, height,
    BufferedImage.TYPE_INT_ARGB);
    Graphics2D g = resizedImage.createGraphics();
    g.drawImage(image, 0, 0, width, height, null);
    g.dispose();
    return resizedImage;
    }   
}

Answer 1

具有图像色彩的色调通常意味着图像使用错误的色彩空间进行渲染，Adobe RGB与sRGB一直是最受欢迎的。尝试在代码中将TYPE_INT_ARGB更改为TYPE_INT_RGB。

Answer 2

您也可以尝试以下类型：BufferedImage.TYPE_3BYTE_BGR

Answer 3

[如果您已经转换了任何图像，而这些图像几乎变成粉红色/红色。

您可以再次将它们转换为RGB。

try {
        File folder = new File("photo/old");
        File[] list = folder.listFiles();
        for (File f : list) {
            String url = f.getAbsolutePath();
            String replce1 = url.replace('\\', '/');
            File file = new File(replce1);
            if (file.exists()) {
                FileInputStream fis = new FileInputStream(file);

                byte[] buff = new byte[fis.available()];
                fis.read(buff);

                BufferedImage bi = ImageIO.read(file); 
                BufferedImage biOriginal = new BufferedImage(1200, 800,
                    BufferedImage.TYPE_INT_RGB);
                Graphics2D g = resizedImage.createGraphics();
                g.drawImage(bi, 0, 0, 1200, 800, null);
                g.dispose();

                fis.close();

                FileOutputStream fos2 = new FileOutputStream("photo/new/"+file.getName());
                ByteArrayOutputStream baos2 = new ByteArrayOutputStream();
                ImageIO.write(biOriginal, Main.extensionWithotDot, baos2);
                baos2.flush();
                byte[] imageInByte2 = baos2.toByteArray();
                fos2.write(imageInByte2);
                fos2.close();
            }
        }

    } catch (Exception e) {
        e.printStackTrace();
    }
