怎么把BufferedImage转成tiff格式的图片 求代码

Answer 1

为什么又要我自己答....
用到的包:pdfbox和开源icafe

 File sourceFile = new File(emailSavePath + "//" + fileName);
        PDDocument doc = PDDocument.load(sourceFile);
        PDFRenderer renderer = new PDFRenderer(doc);
        int pageCount = doc.getNumberOfPages();
        BufferedImage[] images = new BufferedImage[pageCount];
        for (int i = 0; i < pageCount; ++i) {
            BufferedImage image = renderer.renderImageWithDPI(i, 150, ImageType.GRAY);
            images[i] = image;
        }

        FileOutputStream fos = new FileOutputStream(emailSavePath + "\\" + targetFile);

        RandomAccessOutputStream rout = new FileCacheRandomAccessOutputStream(fos);
        ImageParam.ImageParamBuilder builder = ImageParam.getBuilder();
        ImageParam[] param = new ImageParam[1];
        TIFFOptions tiffOptions = new TIFFOptions();
        tiffOptions.setTiffCompression(Compression.JPG);
        tiffOptions.setJPEGQuality(60);
        /*
         * tiffOptions.setXResolution(200); tiffOptions.setYResolution(200);
         */
        builder.imageOptions(tiffOptions);
        builder.colorType(ImageColorType.GRAY_SCALE);
        // builder.bitsPerPixel(1);
        param[0] = builder.build();
        TIFFTweaker.writeMultipageTIFF(rout, param, images);
