我正在使用Java和RCP,并且尝试在Acrobat上显示pdf文档。
我不需要更改它们。
我的这段代码有这个错误。任何想法如何解决此问题?附言:这一次效果很好。
PDFFile pdfFile;
pdfFile = PdfFileLoader.loadPdf(file, new NullProgressMonitor());
PdfDocument pdfDocument = new OneDimensionalPdfDocument(pdfFile, new NullProgressMonitor());
pdfViewer.setPdfDocument(pdfDocument);
Error from PdfDocument pdfDocument = new OneDimensionalPdfDocument(pdfFile, new NullProgressMonitor()) : Unsupport CMap format: 6

最佳答案
看看这些免费的pdf渲染器...

更新
根据http://www.icepdf.org/,
对于基本功能,您必须在类路径中包括
icepdf-core.jar
和icepdf-viewer.jar
。根据要求,您还可以添加SVG支持。取自iceface示例文件夹:
import org.icepdf.ri.common.SwingController;
import org.icepdf.ri.common.SwingViewBuilder;
import javax.swing.*;
/**
* The <code>ViewerComponentExample</code> class is an example of how to use
* <code>SwingController</code> and <code>SwingViewBuilder</code>
* to build a PDF viewer component. A file specified at the command line is
* opened in a JFrame which contains the viewer component.
*
* @since 2.0
*/
public class ViewerComponentExample {
public static void main(String[] args) {
// Get a file from the command line to open
String filePath = args[0];
// build a component controller
SwingController controller = new SwingController();
SwingViewBuilder factory = new SwingViewBuilder(controller);
JPanel viewerComponentPanel = factory.buildViewerPanel();
// add interactive mouse link annotation support via callback
controller.getDocumentViewController().setAnnotationCallback(
new org.icepdf.ri.common.MyAnnotationCallback(
controller.getDocumentViewController()));
JFrame applicationFrame = new JFrame();
applicationFrame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
applicationFrame.getContentPane().add(viewerComponentPanel);
// Now that the GUI is all in place, we can try openning a PDF
controller.openDocument(filePath);
// show the component
applicationFrame.pack();
applicationFrame.setVisible(true);
}
}
上面的代码可帮助您在回转组件上显示PDF。您可以在SWT环境中进行相同的操作(虽然很难看
SwingViewBuilder
..,但是SWT的外观和感觉很不错),也可以使用org.eclipse.swt.awt.SWT_AWT
(有点简单...但是会有swing + swt的外观和感觉)。尽管这两种方法都能解决您的目的。还要检查许可证文件夹中的适用许可证。希望这会有所帮助。
