图像变换会产生红色图像?
我正在尝试通过水平翻转图像并调整其大小来转换图像。问题是,当转换完成后,图片的颜色都很奇怪,它已经变成了微红色调。是否有可能以某种方式解决这个问题,我想我在某处读到这可能是 AWT 库中的一些错误,但我不确定?
这是代码:
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;
}
}
I am trying to transform an image by flipping it horizontally and resizing it. The problem is that when the transformation is done the picture's colors are all weird, it has gotten this reddish tone. Is it possible to fix this somehow, I think I read somewhere that it might be some bug in the AWT library but I am not sure?
Here is the code:
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;
}
}

图像出现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 是长期最受欢迎的颜色空间。尝试在代码中将 TYPE_INT_ARGB 更改为 TYPE_INT_RGB。
Having an image develop a tint usually means the image is being rendered using the wrong colorspace, Adobe RGB vs. sRGB being a perennial favorite. Try changing TYPE_INT_ARGB to TYPE_INT_RGB in your code.
您还可以尝试以下类型:BufferedImage.TYPE_3BYTE_BGR
You can also try the following type: BufferedImage.TYPE_3BYTE_BGR
如果您有任何已转换的图像,并且这些图像几乎是粉红色/红色的。
您可以再次将它们转换为 RGB。
If you have any images already converted and those are almost pinkish/reddish.
You can convert those into RGB again.
