所需jar 包为icepdf-core.jar、icepdf-extra.jar、icepdf-pro-intl.jar、icepdf-pro.jar和icepdf-viewer.jar。
示例代码如下:
package file; import java.awt.image.BufferedImage; import java.awt.image.RenderedImage; import java.io.File; import java.io.IOException; import javax.imageio.ImageIO; import org.icepdf.core.pobjects.Document; import org.icepdf.core.pobjects.Page; import org.icepdf.core.util.GraphicsRenderingHints; public class ICEPdfToImage { public static void main(String[] args) { String filePath = "e:/test/移动方案.pdf"; Document document = new Document(); try { document.setFile(filePath); } catch (Exception ex) { } // save page caputres to file. float scale = 2f; float rotation = 0f; // Paint each pages content to an image and write the image to file for (int i = 0; i < document.getNumberOfPages(); i++) { BufferedImage image = (BufferedImage)document.getPageImage(i, GraphicsRenderingHints.SCREEN, Page.BOUNDARY_CROPBOX, rotation, scale); RenderedImage rendImage = image; // capture the page image to file try { System.out.println("/t capturing page " + i); File file = new File("E:\\test\\移动方案\\image_" + i + ".png"); ImageIO.write(rendImage, "png", file); } catch (IOException e) { e.printStackTrace(); } image.flush(); } // clean up resources document.dispose(); } }
