Java利用Apache PDFBox库实现PPT转PDF的详细教程

要将Java PPT转换为PDF，可以使用Apache PDFBox库。以下是一个简单的示例： 1. 首先，需要添加Apache PDFBox依赖项到项目中。如果使用Maven，可以在pom.xml文件中添加以下依赖： ```xml <dependency> <groupId>org.apache.pdfbox</groupId> <artifactId>pdfbox</artifactId> <version>2.0.24</version> </dependency> ``` 2. 然后，可以使用以下代码将PPT转换为PDF： ```java import org.apache.poi.xslf.usermodel.XMLSlideShow; import org.apache.poi.xslf.usermodel.XSLFSlide; import org.apache.pdfbox.pdmodel.PDDocument; import org.apache.pdfbox.pdmodel.PDPage; import org.apache.pdfbox.pdmodel.common.PDRectangle; import org.apache.pdfbox.pdmodel.PDPageContentStream; import org.apache.pdfbox.pdmodel.graphics.image.PDImageXObject; import java.awt.*; import java.awt.geom.AffineTransform; import java.awt.image.BufferedImage; import java.io.File; import java.io.FileInputStream; import java.io.IOException; import java.util.List; public class PptToPdfConverter { public static void main(String[] args) throws IOException { String pptPath = "path/to/your/ppt/file.pptx"; String pdfPath = "path/to/your/output/pdf/file.pdf"; convertPptToPdf(pptPath, pdfPath); } public static void convertPptToPdf(String pptPath, String pdfPath) throws IOException { try (FileInputStream fis = new FileInputStream(new File(pptPath)); XMLSlideShow ppt = new XMLSlideShow(fis); PDDocument pdf = new PDDocument()) { Dimension pageSize = ppt.getPageSize(); float scale = 1.0f; // 可以根据需要调整缩放比例 int width = (int) (pageSize.width * scale); int height = (int) (pageSize.height * scale); for (XSLFSlide slide : ppt.getSlides()) { PDPage pdfPage = new PDPage(new PDRectangle(width, height)); pdf.addPage(pdfPage); try (PDPageContentStream contentStream = new PDPageContentStream(pdf, pdfPage)) { BufferedImage bufferedImage = new BufferedImage(width, height, BufferedImage.TYPE_INT_RGB); Graphics2D graphics = bufferedImage.createGraphics(); graphics.setPaint(Color.white); graphics.fill(new Rectangle(0, 0, width, height)); graphics.setRenderingHint(RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_ON); graphics.setRenderingHint(RenderingHints.KEY_RENDERING, RenderingHints.VALUE_RENDER_QUALITY); graphics.setRenderingHint(RenderingHints.KEY_INTERPOLATION, RenderingHints.VALUE_INTERPOLATION_BICUBIC); graphics.setRenderingHint(RenderingHints.KEY_FRACTIONALMETRICS, RenderingHints.VALUE_FRACTIONALMETRICS_ON); AffineTransform transform = AffineTransform.getTranslateInstance(0, 0); transform.scale(scale, scale); graphics.drawRenderedShape(slide.getShapes(), transform); PDImageXObject pdImage = PDImageXObject.createFromImage(pdf, bufferedImage, null); contentStream.drawImage(pdImage, 0, 0, width, height); } } pdf.save(pdfPath); } } } ``` 这段代码将读取指定的PPT文件，并将其转换为PDF文件。请确保将`pptPath`和`pdfPath`变量设置为实际的文件路径。 ######[AI写代码神器 | 1030点数解答 | 2024-05-28 13:56:08]
