> Hello,
> I am faced to this issue when i want to convert only the first page of a pdf
> image to a tiff image file.
> This is my java method :
> {code:java}
> private static ByteArrayOutputStream extractFirstPageAsTiff(File pdfsource)
> throws IOException {
> ByteArrayOutputStream out = new ByteArrayOutputStream();
> ImageOutputStream imageOut = new MemoryCacheImageOutputStream(out);
> // Load the PDF
> try (PDDocument pdf = PDDocument.load(pdfsource)) {
> // Initialize PDF renderer
> PDFRenderer ren = new PDFRenderer(pdf);
> // Setup Image Writer
> ImageWriter writer = ImageIO.getImageWritersBySuffix("tiff").next();
> writer.setOutput(imageOut);
> // Setup Image Writer Parameters
> ImageWriteParam params = writer.getDefaultWriteParam();
> params.setCompressionMode(ImageWriteParam.MODE_EXPLICIT);
> params.setCompressionType(COMPRESSION_TYPE_GROUP4FAX);
> // Writer pages to the image writer
> // capture the page image to file
> BufferedImage src = ren.renderImageWithDPI(0, RESOLUTION);
> int[] cmap = new int[] { 0xFF000000, 0xFFFFFFFF };
> BufferedImage src4BitColourDepth = ConvertUtil.convert4(src, cmap);
> // Prepare the Image
> Writer writer.prepareWriteSequence(null);
> writer.writeToSequence(new IIOImage(src4BitColourDepth, null, null),
> params);
> // End Writer Sequence
> writer.endWriteSequence();
> imageOut.close();
> }
> return out;
> }
> {code}
