可以使用iText库来实现ceb文件转pdf,以下是示例代码:
```java
import com.itextpdf.text.Document;
import com.itextpdf.text.PageSize;
import com.itextpdf.text.pdf.PdfWriter;
import com.itextpdf.text.pdf.RandomAccessFileOrArray;
import com.itextpdf.text.pdf.codec.TiffImage;
import java.io.File;
import java.io.FileOutputStream;
public class CebToPdfConverter {
public static void convertCebToPdf(String cebFilePath, String pdfFilePath) throws Exception {
// 创建PDF文档对象
Document document = new Document(PageSize.A4, 0, 0, 0, 0);
PdfWriter.getInstance(document, new FileOutputStream(pdfFilePath));
// 打开ceb文件
RandomAccessFileOrArray raf = new RandomAccessFileOrArray(new File(cebFilePath).getAbsolutePath());
// 将ceb文件转换为tiff格式的图像
int numberOfPages = TiffImage.getNumberOfPages(raf);
for (int i = 1; i <= numberOfPages; i++) {
TiffImage tiffImage = TiffImage.getTiffImage(raf, i);
document.add(tiffImage);
}
// 关闭文件和文档
raf.close();
document.close();
}
}
```
使用方法:
```java
String cebFilePath = "path/to/your/ceb/file.ceb";
String pdfFilePath = "path/to/your/pdf/file.pdf";
CebToPdfConverter.convertCebToPdf(cebFilePath, pdfFilePath);
```
