Im trying to add a TIFF image (CCIT Group 3) to a PDF using Java and PDFBox 1.8.10. There is an image shown on the output file, but its displayed wrong. Its only some black and white pixels.
String outputPath = "/tmp/PDFImage.pdf";
String imagePath = "/tmp/header.tif";
PDDocument doc = new PDDocument();
PDPage page = new PDPage();
doc.addPage(page);
PDPageContentStream content = new PDPageContentStream(doc, page);
PDXObjectImage ximage = new PDCcitt(doc, new RandomAccessFile(new File(imagePath), "r"));
content.drawImage(ximage, 0, 500);
content.close();
doc.save(outputPath);
doc.close();
The PDFBox dependencies says : To write TIFF images a JAI ImageIO Core library will be needed.
I imported the library and and scanned for plugins, but dont found an example how to use is exactly. Someone can help ?

So as the title says I am looking for a way to turn SVG to PNG with Apache Batik and then attach this image to PDF file using PDFBox without actually creating the svg and png anywhere.
Currently I have a web form that has SVG image with selectable parts of it.
When the form is submitted I take the "html" part of the svg meaning I keep something like <svg bla bla> <path bla bla/></svg> in a string that Spring then uses to create a ".svg" file in a given folder, then Batik creates a PNG file in the same folder and then PDFBox attaches it to the PDF - this works fine(code below).
//Get the svg data from the Form and Create the svg file
String svg = formData.getSvg();
File svgFile = new File("image.svg");
BufferedWriter writer = new BufferedWriter(new FileWriter(svgFile));
writer.write(svg);
writer.close();
// Send to Batik to turn to PNG
PNGTranscoder pngTranscode = new PNGTranscoder();
File svgFile = new File("image.svg");
InputStream in = new FileInputStream(svgFile);
TranscoderInput tIn = new TranscoderInput(in);
OutputStream os = new FileOutputStream("image.png");
TranscoderOutput tOut = new TranscoderOutput(os)
pngTranscode .transcode(tIn , tOut);
os.flush();
os.close();
//Send to PDFBox to attach to pdf
File pngfile = new File("image.png");
String path = pngfile.getAbsolutePath();
PDImageXObject pdImage = PDImageXObject.createFromFile(path, pdf);
PDPageContentStream contents = new PDPageContentStream(pdf, pdf.getPage(1));
contents.drawImage(pdImage, 0, pdf.getPage(1).getMediaBox().getHeight() - pdImage.getHeight());
contents.close();
As you can see there are a lot of files and stuff (need to tidy it up a bit), but is it possible to do this on the run without the creation and constant fetching of the svg and png files?
Given the suggestion in the comments I opted for using ByteArrayOutputStream, ByteArrayInputStream, BufferedImage and LosslessFactory. Its a bit slower than the saving (if you go through it in debug as seems the BufferedImage goes on a holiday first before creating the image).
The sources I found to use are: How to convert SVG into PNG on-the-fly and Print byte[] to pdf using pdfbox
byte[] streamBytes = IOUtils.toByteArray(new ByteArrayInputStream(formData.getSvg().getBytes()));
PNGTranscoder pngTranscoder = new PNGTranscoder();
ByteArrayOutputStream os = new ByteArrayOutputStream();
pngTranscoder.transcode(new TranscoderInput(new ByteArrayInputStream(streamBytes)), new TranscoderOutput(os));
InputStream is = new ByteArrayInputStream(os.toByteArray());
BufferedImage bim = ImageIO.read(is);
PDImageXObject pdImage = LosslessFactory.createFromImage(pdf, bim);
PDPageContentStream contents = new PDPageContentStream(pdf, pdf.getPage(1));
contents.drawImage(pdImage, 0, pdf.getPage(1).getMediaBox().getHeight() - pdImage.getHeight());
contents.close();
Based on the comments and links provided by D.V.D., I also worked through the problem. I just wanted to post the simple but full example, for anyone wanting to review in the future.
public class App {
private static String OUTPUT_PATH = "D:\\so52875145\\output\\PdfWithPngImage.pdf";
public static void main(String[] args) {
try {
// obtain the SVG source (hardcoded here, but the OP would obtain the String from form data)
byte[] svgByteArray = "<svg xmlns=\"http://www.w3.org/2000/svg\" xmlns:xlink=\"http://www.w3.org/1999/xlink\"><polygon points=\"200,10 250,190 160,210\" style=\"fill:lime;stroke:purple;stroke-width:1\" /></svg>".getBytes();
System.out.println("Converted svg to byte array...");
// convert SVG into PNG image
PNGTranscoder pngTranscoder = new PNGTranscoder();
ByteArrayOutputStream os = new ByteArrayOutputStream();
pngTranscoder.transcode(new TranscoderInput(new ByteArrayInputStream(svgByteArray)), new TranscoderOutput(os));
System.out.println("Transcoded svg to png...");
// create PDF, and add page to it
PDDocument pdf = new PDDocument();
pdf.addPage(new PDPage());
// generate in-memory PDF image object, using the transcoded ByteArray stream
BufferedImage bufferedImage = ImageIO.read( new ByteArrayInputStream(os.toByteArray()) );
PDImageXObject pdImage = LosslessFactory.createFromImage(pdf, bufferedImage);
System.out.println("Created PDF image object...");
// write the in-memory PDF image object to the PDF page
PDPageContentStream contents = new PDPageContentStream(pdf, pdf.getPage(0));
contents.drawImage(pdImage, 0, 0);
contents.close();
System.out.println("Wrote PDF image object to PDF...");
pdf.save(OUTPUT_PATH);
pdf.close();
System.out.println("Saved PDF to path=[" + OUTPUT_PATH + "]");
}
catch (Exception e) {
e.printStackTrace();
}
}

I am trying to create pdf in java using pdfbox 1.8, but problem is I am not able to show CMYK image on pdf so I try to solution on same like below code:
File filePath = new File("C:/Users/msuryawanshi/Documents/10734730431625_C1LA.jpg");
JPEGImageDecoder jpegDecoder = JPEGCodec.createJPEGDecoder(new FileInputStream(filePath));
BufferedImage image = jpegDecoder.decodeAsBufferedImage();
imageUrl = "http://extranet.handgards.com/gs1/10734730431625_C1LA.jpg";
File f = new File("C:/Users/msuryawanshi/Documents/10734730431625_C1LA.jpg");
String url = "http://extranet.handgards.com/gs1/10734730431625_C1LA.jpg";
Iterator readers = ImageIO.getImageReadersByFormatName("JPEG");
ImageReader reader = null;
while (readers.hasNext()) {
reader = (ImageReader) readers.next();
if (reader.canReadRaster()) {
break;
}
}
//Stream the image file (the original CMYK image)
ImageInputStream input = ImageIO.createImageInputStream(f);
reader.setInput(input);
//Read the image raster
Raster raster = reader.readRaster(0, null);
//Create a new RGB image
BufferedImage bi = new BufferedImage(raster.getWidth(), raster.getHeight(),
BufferedImage.TYPE_4BYTE_ABGR);
//Fill the new image with the old raster
bi.getRaster().setRect(raster);
PDXObjectImage ximage = new PDPixelMap(document, bi);
contentStream.drawXObject(ximage, margin + 5, texty, 170, 100);
but image is not meaningful, I have attached output pdf and original image which i want display on my pdf. please help for the same.
PDFBox doesn't support embedding CMYK images at all because java itself can't read such images. You might be able to embed it as an RGB image by using the twelvemonkeys library instead of Java ImageIO to read the JPEG into a BufferedImage. From there, just use PDPixelMap (in 1.8) or LosslessFactory (in 2.0).
I'm writing a simple scanning application using jfreesane and Apache PDFBox.
Here is the scanning code:
InetAddress address = InetAddress.getByName("192.168.0.17");
SaneSession session = SaneSession.withRemoteSane(address);
List<SaneDevice> devices = session.listDevices();
SaneDevice device = devices.get(0);
device.open();
device.getOption("resolution").setIntegerValue(300);
BufferedImage bimg = device.acquireImage();
File file = new File("test_scan.png");
ImageIO.write(bimg, "png", file);
device.close();
And making PDF:
PDDocument document = new PDDocument();
float width = bimg.getWidth();
float height = bimg.getHeight();
PDPage page = new PDPage(new PDRectangle(width, height));
document.addPage(page);
PDImageXObject pdimg = LosslessFactory.createFromImage(document, bimg);
PDPageContentStream stream = new PDPageContentStream(document, page, PDPageContentStream.AppendMode.APPEND, true);
stream.drawImage(pdimg, 0, 0);
stream.close();
document.save(filename);
document.close();
And here is the result:
As you can see the PDF image is more "pale" (saturation? - sorry, I'm not good at color theory and don't know how to name it correctly).
What I have found out:
Printing BufferedImage to JLabel using JLabel(new ImageIcon(bimg))
constructor produces the same result as with PDF ("pale" colors)
so I guess PDFBox is not the reason.
Changing scanning resolution -
no effect.
bimg.getTransparency() returns 1 (OPAQUE)
bimg.getType() returns 0 (TYPE_CUSTOM)

There was an issue in JFreeSane with colorspaces, it was fixed in version 0.97:

I try to create a PDF file with PDFBox and then to create from it an image using commercial library jPDFImages (Qoppa software). Yes, i know that PDFBox is able too to create images from PDFs, but for some reasons I need to use commercial library.
I created PDF file and pass it to jPDFImajes, but I have an error: "Unable to find PDF trailer". Qoppa software describe this error.
The problem is seems to be in the PDF trailer, which is created by PDFBox, but I don`t understand how to set it up in right mode? (I have a problem only with PDFs created with PDFBox)
Here is my code for pdf creation:
public void createPDFFromImage( String file) throws Exception {
PDDocument doc = null;
try {
doc = new PDDocument();
BufferedImage bufferedImage = ImageIO.read(new File(/home/.../files/test.png));
PDPage page = new PDPage();
doc.addPage( page );
PDJpeg ximage = new PDJpeg(doc,bufferedImage, (float) 0.95);
PDPageContentStream contentStream = new PDPageContentStream(doc, page);
contentStream.drawXObject(ximage, x, y, W, H);
contentStream.close();
doc.save(file);
} finally {
if( doc != null ) {
doc.close();
}
}
}
Here is an error from commercial library:
java.lang.RuntimeException: com.qoppa.pdf.PDFException: Unable to find PDF trailer.
Caused by: com.qoppa.pdf.PDFException: Unable to find PDF trailer.
I think the problem is, how do I create pdf. Maybe I need to add some information to the pdf to make it valid?
I'm writing a java app that creates a pdf from scratch using the pdfbox library.
I need to place a jpg image in one of the page.
I'm using this code:
PDDocument document = new PDDocument();
PDPage page = new PDPage(PDPage.PAGE_SIZE_A4);
document.addPage(page);
PDPageContentStream contentStream = new PDPageContentStream(document, page);
/* ... */
/* code to add some text to the page */
/* ... */
InputStream in = new FileInputStream(new File("c:/myimg.jpg"));
PDJpeg img = new PDJpeg(document, in);
contentStream.drawImage(img, 100, 700);
contentStream.close();
document.save("c:/mydoc.pdf");
When I run the code, it terminates successfully, but if I open the generated pdf file using Acrobat Reader, the page is completely white and the image is not placed in it.
The text instead is correctly placed in the page.
Any hint on how to put my image in the pdf?
Definitely add the page to the document. You'll want to do that, but I've also noticed that PDFBox won't write out the image if you create the PDPageContentStream BEFORE the PDJpeg. It's unexplained why this is so, but if you look close at the source of ImageToPDF that's what they do. Create the PDPageContentStream after PDJpeg and it magically works.
...
PDJpeg img = new PDJpeg(document, in);
PDPageContentStream stream = new PDPageContentStream( doc, page );
...
Looks like you're missing just a document.addPage(page) call.
See also the ImageToPDF example class in PDFBox for some sample code.
this is how default constructor for PDPageContentStream looks like:
public PDPageContentStream(PDDocument document, PDPage sourcePage) throws IOException
{
this(document, sourcePage, AppendMode.OVERWRITE, true, false);
}
Problem is AppendMode.OVERWRITE for me using another constructor with parameter PDPageContentStream.AppendMode.APPEND resolved a problem
For me this worked:
PDPageContentStream contentStream =
new PDPageContentStream(document, page, PDPageContentStream.AppendMode.APPEND, true, false);
