I study on a web sharing project in jsf.In this project users can upload documents such as .doc,.pdf,.ppt,..etc . I want show this documents first pages as a thumbnail. After some googling around I found Apache POI.Can anybody has any suggestion for my problem? How can I return thumbnail image of word doc's first page? I try this code.This code just get first picture that word doc contains:
POIFSFileSystem fs = new POIFSFileSystem(new FileInputStream("d:\\test.doc"));
HWPFDocument doc = new HWPFDocument(fs);
PicturesTable pt=doc.getPicturesTable();
List<Picture> p=pt.getAllPictures();
BufferedImage image=ImageIO.read(new ByteArrayInputStream(p.get(0).getContent()));
ImageIO.write(image, "JPG", new File("d:\\test.jpg"));
What's you are doing make nothing. HWPFDocument can extract thumbnail embedded in document (when saving files, check on 'add preview' option). So HWPFDocument can extract only thumbnail of documents having thumbnail.
Even, to do that, you have to make:
{code}
static byte[] process(File docFile) throws Exception {
final HWPFDocumentCore wordDocument = AbstractWordUtils.loadDoc(docFile);
SummaryInformation summaryInformation = wordDocument.getSummaryInformation();
System.out.println(summaryInformation.getAuthor());
System.out.println(summaryInformation.getApplicationName() + ":" + summaryInformation.getTitle());
Thumbnail thumbnail = new Thumbnail(summaryInformation.getThumbnail());
System.out.println(thumbnail.getClipboardFormat());
System.out.println(thumbnail.getClipboardFormatTag());
return thumbnail.getThumbnailAsWMF();
}
{code}
after that, you have to probably convert WMF file format to more common format (jpeg, png...). ImageMagick can help.

I am running into strange issue with generated pdf's from iText7. The generated pdf's are opening properly in Adobe reader and Chrome browser. But the same pdf is opening partially in the Firefox browser. I am getting the below message in Firefox. The strange thing is other pdf, which are not generated via iText are properly rendering in firefox.
Java code
public static byte[] createPdf(List<String> htmlPages, PageSize pageSize, boolean rotate) throws IOException {
ConverterProperties properties = new ConverterProperties();
// Register classpath protocol handler to be able to load HTML resources from class patch
org.apache.catalina.webresources.TomcatURLStreamHandlerFactory.register();
properties.setBaseUri("classpath:/");
// properties.setBaseUri(baseUri);
FontProvider fontProvider = new DefaultFontProvider(true,false,false);
properties.setFontProvider(fontProvider);
ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();
PdfDocument pdf = new PdfDocument(new PdfWriter(byteArrayOutputStream));
PdfMerger merger = new PdfMerger(pdf);
for (String htmlPage : htmlPages) {
ByteArrayOutputStream baos = new ByteArrayOutputStream();
PdfDocument temp = new PdfDocument(new PdfWriter(baos));
if(rotate) {
temp.setDefaultPageSize(pageSize.rotate()); /** Page Size and Orientation */
} else {
temp.setDefaultPageSize(pageSize); /** Page Size and Orientation */
}
HtmlConverter.convertToPdf(htmlPage, temp, properties);
temp = new PdfDocument(new PdfReader(new ByteArrayInputStream(baos.toByteArray())));
merger.merge(temp, 1, temp.getNumberOfPages());
temp.close();
}
pdf.close();
byteArrayOutputStream.flush(); // Tried this
byteArrayOutputStream.close(); // Tried this
byte[] byteArray = byteArrayOutputStream.toByteArray();
Timestamp timestamp = new Timestamp(System.currentTimeMillis());
try (FileOutputStream fileOuputStream = new FileOutputStream("D:\\Labels\\Label_"+timestamp.getTime()+".pdf")){
fileOuputStream.write(byteArray);
}
return byteArray;
}
Thanks in advance.
Edit 1:
You can find pdf and html/css for reproducing issue here.
When you embedded the images into your html using base64 URIs, something weird happened to the image of the barcode: Instead of the 205×59 bitmap image in labelData/barcode.png you embedded a 39578×44 image! (Yes, an image nearly a thousand times wider than high...)
The iText HtmlConverter embedded that image just fine but apparently Firefox has issues displaying an image with those dimensions even though (or probably because?) it is transformed into the desired dimensions (about four times wider than high) on the label. At least my Firefox installation stops drawing label contents right here. (Beware, the order of drawing in the PDF content is not identical to the of the HTML elements; in particular in the PDF the number 3232000... is drawn right before the barcode, not afterwards!)
On Firefox:
On Acrobat Reader:
Thus, you may want to check the transformation of the bar code image to the base64 image URI in your HTML file.
I am trying to go from text to pdf but have only one of the pages rotated 90 degress. Main reason is that some of my text documents are a bit too large and need to be in landscape to look normal. I have tried a few things but it seems like everything rotates the text too. Is there an easy way to rotate the pdf to landscape but keep the text the same rotation?
OutputStream outputStream = response.getOutputStream();
PDFMergerUtility pdfMergerUtility = new PDFMergerUtility();
Map<String, Documents> documents = getDocuments(user, documentReports);
try (PDDocument documentToPrint = new PDDocument()){
for(Document doc : documentReports){
TextToPDF textToPDF = new TextToPDF();
textToPDF.setFont(PDType1Font.COURIER);
textToPDF.setFontSize(8);
Document documentReport = documents.get(doc.getId());
try(PDDocument pdDocument = textToPDF.createPDFFromText(new InputStreamReader(new ByteArrayInputStream(documentReport.getReportText().getBytes())))) {
pdfMergerUtility.appendDocument(documentToPrint, pdDocument);
}
}
pdfMergerUtility.mergeDocuments(MemoryUsageSetting.setupMainMemoryOnly());
LocalDateTime localUtcTime = Java8TimeUtil.getCurrentUtcTime();
documentToPrint.getDocumentInformation().setTitle(localUtcTime.toString());
response.setHeader("Content-Disposition", "inline; filename=" + localUtcTime + ".pdf");
response.setContentType("application/pdf");
documentToPrint.save(outputStream);
}
So this might not work for everyone but I figured it out for my specific requirement. TextToPDF has a method called setLandscape before creating the pdf from text. textToPDF.setLandscape(true);
I'am looking for some "stable" method to convert DOCX file from MS WORD into PDF. Since now I have used OpenOffice installed as listener but it often hangs. The problem is that we have situations when many users want to convert SXW,DOCX files into PDF at the same time. Is there some other possibility? I tryed with examples from this site: https://angelozerr.wordpress.com/2012/12/06/how-to-convert-docxodt-to-pdfhtml-with-java/ but the output result is not good (converted documents have errors and layout is quite modified).
here is "source" docx document:
here is document converted with docx4j with some exception text inside document. Also the text in upper right corner is missing.
this one is PDF created with OpenOffice as converter from docx to pdf. Some text is missing "upper right corner"
Is there some other option to convert docx into pdf with Java?
There are lot of methods to do conversion
One of the used method is using POI and DOCX4j
InputStream is = new FileInputStream(new File("your Docx PAth"));
WordprocessingMLPackage wordMLPackage = WordprocessingMLPackage
.load(is);
List sections = wordMLPackage.getDocumentModel().getSections();
for (int i = 0; i < sections.size(); i++) {
wordMLPackage.getDocumentModel().getSections().get(i)
.getPageDimensions();
}
Mapper fontMapper = new IdentityPlusMapper();
PhysicalFont font = PhysicalFonts.getPhysicalFonts().get(
"Comic Sans MS");//set your desired font
fontMapper.getFontMappings().put("Algerian", font);
wordMLPackage.setFontMapper(fontMapper);
PdfSettings pdfSettings = new PdfSettings();
org.docx4j.convert.out.pdf.PdfConversion conversion = new org.docx4j.convert.out.pdf.viaXSLFO.Conversion(
wordMLPackage);
//To turn off logger
List<Logger> loggers = Collections.<Logger> list(LogManager
.getCurrentLoggers());
loggers.add(LogManager.getRootLogger());
for (Logger logger : loggers) {
logger.setLevel(Level.OFF);
}
OutputStream out = new FileOutputStream(new File("Your OutPut PDF path"));
conversion.output(out, pdfSettings);
System.out.println("DONE!!");
This works perfect and even tried on multiple DOCX files.
It's my first time posting here :)
I want with apache POI to embed a file inside a .docx and reference it via an icon or a link inside the document.
I guess I've managed to embed the file.
My problem : I can't display a reference to the embed file.
To illustrate my problem:
With the following code, I've manage to embed inside myWord.docx the file "first.txt" at the location "/word/embeddings/first.txt".
I don't know how to reference it.
This is my code :
public void saveToDocx(OutputStream myOutputStream){
Resource r = new ClassPathResource("/myWord.docx") ;
try (FileInputStream fis= new FileInputStream(r.getFile())){
OPCPackage pkg = OPCPackage.open(fis);
XWPFDocument docx = new XWPFDocument(pkg);
fis.close();
// first.txt
final PackagePartName partName = PackagingURIHelper.createPartName("/word/embeddings/first.txt");
final PackagePart pkgPart = pkg.createPart(partName, "application/vnd.openxmlformats-officedocument.oleobject");
final OutputStream partOutputStream = pkgPart.getOutputStream();
partOutputStream.write("test test test".getBytes());
partOutputStream.close();
pkgPart.addRelationship(partName, TargetMode.INTERNAL, "http://schemas.openxmlformats.org/officeDocument/2006/relationships/oleObject");
//image.jpg
String imageName = "C:/image.jpg";
InputStream imageIS = new FileInputStream(imageName);
imageIS.close();
imgPartOutputStream.close();
//add simple picture to my document
XWPFParagraph myParagraph = docx.createParagraph();
XWPFRun run = myParagraph.createRun();
run.addPicture(imageIS, XWPFDocument.PICTURE_TYPE_JPEG, imageName, Units.toEMU(77.25), Units.toEMU(49.5));
docx.write(myOutputStream);
//pkg.save(myOutputStream); there is a difference between this and docx.write ?
}catch(Exception e){
e.printStackTrace();
}
}
Can someone please try to help me? I'm really stuck (since last Friday). Thanks guys!
(Do forgive me for my grammar, i'm not a native :/)
I am desperately trying to insert an image into an existing pdf with droidtext.
The original version of this project was made with iText.
So the code already exists and was modified to fit for Android.
What I do is I take an existing PDF as background.
Insert text and crosses at specified positions within this pdf.
Like filling out a form.
This works quite well so far without changing the code drastically.
Now I want to set an image to the bottom of the page to sign the form.
I used my original code and adapted it a little.
Which doesn't work at all.
I tried to set the image at a specific position. Maybe that was the error.
So i tried to do it the "official" way.
The Pengiuns.jpg image is located on the sd-card.
try {
Document document = new Document();
File f=new File(Environment.getExternalStorageDirectory(), "SimpleImages.pdf");
PdfWriter.getInstance(document,new FileOutputStream(f));
document.open();
document.add(new Paragraph("Simple Image"));
String path = Environment.getExternalStorageDirectory()+"/Penguins.jpg";
if (new File(path).exists()) {
System.out.println("filesize: " + path + " = " + new File(path).length());
}
Image image =Image.getInstance(path);
document.add(image);
document.close();
} catch (Exception ex) {
System.out.println("narf");
}
But still no image at all.
What I get is an PDF with the words "Simple Image" on it and nothing else.
I can access the picture. I get the correct filesize by the if().
No exceptions are thrown.
So my questions are, how do I get an Image located on the SD-Card into my pdf?
What is the mistake here?
But most importantly how do I set the image to a specific location with size within the pdf?
In my original code i use setAbsolutePosition( x, y ) for that.
Eclipse is not complaining when I use it in the code but is it really working?
The reason why you are getting the "Simple Image" is because you have it in Paragraph. In order to add an image, use:
Image myImg1 = Image.getInstance(stream1.toByteArray());
If you want to have it as a footer in the last page you can use the following code but it works with text. You can try to manipulate it for image:
Phrase footerText = new Phrase("THIS REPORT HAS BEEN GENERATED USING INSPECTIONREPORT APP");
HeaderFooter pdfFooter = new HeaderFooter(footerText, false);
doc.setFooter(pdfFooter);
Here is sample code. Here I have uploaded an image to Imageview and then added to pdf. Hope this helps.
private String NameOfFolder = "/InspectionReport";
Document doc = new Document();
try { //Path to look for App folder
String path = Environment.getExternalStorageDirectory().getAbsolutePath() + NameOfFolder;
String CurrentDateAndTime= getCurrentDateAndTime();
// If App folder is not there then create one
File dir = new File(path);
if(!dir.exists())
dir.mkdirs();
//Creating new file and naming it
int i = 1;
File file = new File(dir, "Inspection"+Integer.toString(i)+"-" + CurrentDateAndTime+".pdf");
while(file.exists()) {
file = new File(dir, "Inspection"+Integer.toString(i++)+"-" + CurrentDateAndTime+".pdf");}
String filep= file.toString();
FileOutputStream fOut = new FileOutputStream(file);
Log.d("PDFCreator", "PDF Path: " + path);
PdfWriter.getInstance(doc, fOut);
Toast.makeText(getApplicationContext(),filep , Toast.LENGTH_LONG).show();
//open the document
doc.open();
ImageView img1 = (ImageView)findViewById(R.id.img1);
ByteArrayOutputStream stream1 = new ByteArrayOutputStream();
Bitmap bitmap1 = ((BitmapDrawable)img1.getDrawable()).getBitmap();
bitmap1.compress(Bitmap.CompressFormat.JPEG, 100 , stream1);
Image myImg1 = Image.getInstance(stream1.toByteArray());
myImg1.setAlignment(Image.MIDDLE);
doc.add(myImg1);
Try following code:
/* Inserting Image in PDF */
ByteArrayOutputStream stream = new ByteArrayOutputStream();
Bitmap bitmap = BitmapFactory.decodeResource(getBaseContext().getResources(), R.drawable.android);
bitmap.compress(Bitmap.CompressFormat.JPEG, 100 , stream);
Image myImg = Image.getInstance(stream.toByteArray());
myImg.setAlignment(Image.MIDDLE);
//add image to document
doc.add(myImg);
