Apache Commons Imaging - convert tiff to jpg
问题
我需要使用Apache Commons Imaging将一个 tiff 图像转换为 jpg 格式。我尝试过了，但是我无法弄清楚如何使用这个库来实现。
final BufferedImage image = Imaging.getBufferedImage(new File(image));
final ImageFormat format = ImageFormats.JPEG;
final Map<String, Object> params = new HashMap<>();
return Imaging.writeImageToBytes(image, format, params);
其中 image 是我要转换的 tiff 文件，但是我得到了以下错误信息：
> org.apache.commons.imaging.ImageWriteException: 无法写入此图像格式（Jpeg-Custom）。
我不明白我做错了什么，有人可以帮帮我吗？

I need to convert a tiff image into a jpg one using Apache Commons Imaging.
I tried to but I can't figure out how to do it using this library.
final BufferedImage image = Imaging.getBufferedImage(new File(image));
final ImageFormat format = ImageFormats.JPEG;
final Map<String, Object> params = new HashMap<>();
return Imaging.writeImageToBytes(image, format, params);
Where image is my tiff file to be converted, but I get
> org.apache.commons.imaging.ImageWriteException: This image format (Jpeg-Custom) cannot be written.
I don't understand what I'm doing wrong could someone help?

尝试使用 Java AWT：
import java.awt.Color;
import java.awt.image.BufferedImage;
import java.io.File;
import java.io.IOException;
import javax.imageio.ImageIO;
和代码部分：
// 读取 TIFF 图像文件
BufferedImage tiffImage = ImageIO.read(new File("tiff-image.tiff"));
// 在写入之前准备图像 - 使用相同的尺寸
BufferedImage jpegImage = new BufferedImage(
tiffImage.getWidth(),
tiffImage.getHeight(),
BufferedImage.TYPE_INT_RGB);
// 从原始 TIFF 图像绘制到新的 JPEG 图像
jpegImage.createGraphics().drawImage(tiffImage, 0, 0, Color.WHITE, null);
// 将图像以 JPEG 格式写入磁盘
ImageIO.write(jpegImage, "jpg", new File("jpeg-image.jpg"));

Try the use of java AWT:
import java.awt.Color;
import java.awt.image.BufferedImage;
import java.io.File;
import java.io.IOException;
import javax.imageio.ImageIO;
And code:
// TIFF image file read
BufferedImage tiffImage = ImageIO.read(new File("tiff-image.tiff"));
// Prepare the image before writing - with same dimensions
BufferedImage jpegImage = new BufferedImage(
tiffImage.getWidth(),
tiffImage.getHeight(),
BufferedImage.TYPE_INT_RGB);
// Draw image from original TIFF to the new JPEG image
jpegImage.createGraphics().drawImage(tiffImage, 0, 0, Color.WHITE, null);
// Write the image as JPEG to disk
ImageIO.write(jpegImage, "jpg", new File("jpeg-image.jpg"));
