pdfbox-3.0.0-RC1.jar
要从PDF文件中删除图片,可以使用Apache PDFBox 3.0.0-RC1中的以下代码:
```
import java.io.File;
import java.io.IOException;
import org.apache.pdfbox.cos.COSName;
import org.apache.pdfbox.pdmodel.PDDocument;
import org.apache.pdfbox.pdmodel.PDPage;
import org.apache.pdfbox.pdmodel.graphics.image.PDImageXObject;
public class RemoveImageFromPDF {
public static void main(String[] args) throws IOException {
// Load the PDF document
File file = new File("sample.pdf");
PDDocument document = PDDocument.load(file);
// Get the first page of the PDF document
PDPage page = document.getPage(0);
// Get all the images on the page
for (PDImageXObject image : page.getResources().getXObjectNames().stream()
.map(name -> page.getResources().getXObject(name))
.filter(obj -> obj instanceof PDImageXObject)
.map(obj -> (PDImageXObject) obj)
.toArray(PDImageXObject[]::new)) {
// Remove the image from the page resources dictionary
page.getResources().getCOSObject().removeItem(COSName.XOBJECT, image.getCOSObject());
// Remove the image from the document's object pool
document.getDocument().getObjects().remove(image.getCOSObject());
}
// Save the modified document
document.save("sample_without_images.pdf");
// Close the document
document.close();
}
}
```
该代码将从第一页中的PDF文档中删除所有图像,并将修改后的文档保存到“sample_without_images.pdf”文件中。请注意,这将从文档中永久删除图像,因此在执行此操作之前请务必备份原始文档。
