Here's the code I used. You have to either change the sources so that
TIFFUtil is a public class, or copy the TIFFUtil source code, or just
add this segment to a local copy of the PDFBox sources.
void saveAsMultipageTIFF(ArrayList<BufferedImage> bimTab, String
filename, int dpi)
throws IOException
{
Iterator<ImageWriter> writers =
ImageIO.getImageWritersByFormatName("tiff");
ImageWriter imageWriter = writers.next();
ImageOutputStream ios = ImageIO.createImageOutputStream(new
File(filename));
imageWriter.setOutput(ios);
imageWriter.prepareWriteSequence(null);
for (BufferedImage image : bimTab)
{
ImageWriteParam param = imageWriter.getDefaultWriteParam();
IIOMetadata metadata =
imageWriter.getDefaultImageMetadata(new ImageTypeSpecifier(image), param);
param.setCompressionMode(ImageWriteParam.MODE_EXPLICIT);
TIFFUtil.setCompressionType(param, image);
TIFFUtil.updateMetadata(metadata, image, dpi);
imageWriter.writeToSequence(new IIOImage(image, null,
metadata), param);
}
imageWriter.endWriteSequence();
imageWriter.dispose();
ios.flush();
ios.close();
}
