通天战队|Word文档转换：如何使用Aspose在Java中将Word和图像转换为PDF( 二 )


// The builder makes it simple to add content to the document.
Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);
// Load images from the disk using the appropriate reader.
// The file formats that can be loaded depends on the image readers available on the machine.
ImageInputStream iis = ImageIO.createImageInputStream(new File(inputFileName));
ImageReader reader = ImageIO.getImageReaders(iis).next(); reader.setInput(iis, false);
// Get the number of frames in the image.
int framesCount = reader.getNumImages(true);
// Loop through all frames. for (int frameIdx = 0; frameIdx < framesCount; frameIdx++) {
// Insert a section break before each new page, in case of a multi-frame image.
if (frameIdx != 0)
builder.insertBreak(BreakType.SECTION_BREAK_NEW_PAGE);
// Select active frame.
BufferedImage image = reader.read(frameIdx);
// We want the size of the page to be the same as the size of the image.
// Convert pixels to points to size the page to the actual image size.
PageSetup ps = builder.getPageSetup();
ps.setPageWidth(ConvertUtil.pixelToPoint(image.getWidth()));
ps.setPageHeight(ConvertUtil.pixelToPoint(image.getHeight()));
// Insert the image into the document and position it at the top left corner of the page.
builder.insertImage( image, RelativeHorizontalPosition.PAGE, 0,
RelativeVerticalPosition.PAGE, 0, ps.getPageWidth(), ps.getPageHeight(), WrapType.NONE); }
if (iis != null) { iis.close(); reader.dispose(); }
doc.save(outputFileName); }
