I would like to add total page count as a custom property like ms word does as follow.
Is it possible to similar things for pdf? I am also using aspose for file conversion. I converter many kind of file types to pdf but if we want to show also the document's pagen count as the custom property.
This is from the Aspose Newsgroup:
//open document
Aspose.Pdf.Document pdfDocument = new Aspose.Pdf.Document("Test.pdf");
//set properties
pdfDocument.Metadata["xmp:Nickname"] = "Nickname";
pdfDocument.Metadata["xmp:CreatorTool"] = "Test Value";
pdfDocument.Metadata["xmp:CustomProperty"] = "Custom Value";
//Convert to PDF/A compliant document
pdfDocument.Validate("log.xml", PdfFormat.PDF_A_1A);
pdfDocument.Convert("log.xml", PdfFormat.PDF_A_1A, ConvertErrorAction.Delete);
//save output document
pdfDocument.Save("output_XMP.pdf");
Is this what you are looking for?

Editing a PDF (specifically a user-editable form) using Adobe Acrobat, and using the PDF JavaScript API, is it possible to style separate substrings within a field value? Is there a markup language used, for example?
A bit of pseudocode for what I’m talking about:
This word is <red>red</red>, this word is <bold>bold</bold>. I have spoken.
The answer is to:
a) Make sure the field type is rich text, and
b) Use Adobe's JavaScript methods to set spans within the field's richValue property with the formatting desired, for example:
var field = this.getField("MyRichTextField");
var spans = new Array();
spans[0] = new Object();
spans[0].text = "This word is ";
spans[1] = new Object();
spans[1].text = "red";
spans[1].textColor = color.red;
field.richValue = spans;
Further details and a list of span properties can be found in Acrobat JavaScript Scripting Reference (https://www.adobe.com/content/dam/acom/en/devnet/acrobat/pdfs/Acro6JS.pdf)
I am using grails 2.5.2.
I have created a table which shows all the data from database to gsp page and now i need to save that shown data in a pdf format with a button click.What will be the best way to show them into a PDF and save it to my directory. please Help
You can use itext for converting HTML into pdf using the code below:
public void createPdf(HttpServletResponse response, String args, String css, String pdfTitle) {
response.setContentType("application/force-download")
response.setHeader("Content-Disposition", "attachment;filename=${pdfTitle}.pdf")
Document document = new Document()
Rectangle one = new Rectangle(900, 600)
document.setPageSize(one)
PdfWriter writer = PdfWriter.getInstance(document, response.getOutputStream())
document.open()
ByteArrayInputStream bis = new ByteArrayInputStream(args.toString().getBytes())
ByteArrayInputStream cis = new ByteArrayInputStream(css.toString().getBytes())
XMLWorkerHelper.getInstance().parseXHtml(writer, document, bis, cis)
document.close()
}
Though answering this question late,take a look at grails export plugin.It will be useful if you want to export your data to excel and pdf( useful only if there is no in pre-defined template to export).
Got idea from itext. Used itext 2.1.7 and posted all the values to pdf from a controller method. Used images as background and paragraph and phrase to show values from database.
I am now trying to modify a PDF file with ONLY text content. When I use
TextRenderInfo.getFont()
it returns me a Font which is actually an indirect object.
pdf.inderect.object.belong.to.other.pdf.document.Copy.object.to.current.pdf.document
would be thrown in this case when close the PdfDocument.
Is there a way to let me reuse this Font in a new PDF file? OR, is there a way to in-place edit the text content in PDF (without changing the font, color, fontSize)?
I'm using itext7.
Thanks
First of all, from the error message I see that you are not using the latest version of iText, which is 7.0.2 at the moment. So I recommend that you update your iText version.
Secondly, it is indeed possible to use a font in another document. But to do that, you first have to copy the corresponding font object to that other document (as stated in the exception message by the way). But you should be warned that this approach has some limitations, e.g. in case of a font subset, you will only be able to use the glyphs that are present in the original font subset in the source document and will not be able to use other glyphs.
PdfFont font = textRenderInfo.getFont(); // font from source document
PdfDocument newPdfDoc = ... // new PdfDocument you want to write some text to
// copy the font dictionary to the new document
PdfDictionary fontCopy = font.getPdfObject().copyTo(newPdfDoc);
// create a PdfFont instance corresponding to the font in the new document
PdfFont newFont = PdfFontFactory.createFont(fontCopy);
// Use newFont in newPdfDoc, e.g.:
Document doc = new Document(newPdfDoc);
doc.add(new Paragraph("Hello").setFont(newFont));
I want to write a Java code which update a document's content from a MS-word file to a pdf file in IBM Filenet Content Engine 4.5.No conversion as of now required, just updation of the content only. Metadata Properties etc remain unchanged from the word file.
Many Thanks
Do you have any problem using code samples from the documentation?
Based on Setting a Document's Content:
// references to the document and file you are working with
Document document;
File file;
document.checkout(ReservationType.EXCLUSIVE, null, null, null);
document.save(RefreshMode.REFRESH);
Document reservation = (Document) document.get_Reservation();
ContentTransfer contentTransfer = Factory.ContentTransfer.createInstance();
InputStream inputStream = new FileInputStream(file);
ContentElementList contentList = Factory.ContentTransfer.createList();
contentTransfer.setCaptureSource(inputStream);
contentList.add(contentTransfer);
reservation.set_ContentElements(contentList);
reservation.save(RefreshMode.REFRESH);
reservation.checkin(AutoClassify.DO_NOT_AUTO_CLASSIFY, CheckinType.MAJOR_VERSION);
reservation.save(RefreshMode.REFRESH);
How do I figure out the font family and the font size of the words in a pdf document? We are actually trying to generate a pdf document programmatically using iText, but we are not sure how to find out the font family and the font size of the original document which needs to be generated. document properties doesn't seem to contain this information
Fonts are stored in the catalog (I suppose in a sub-catalog of type font). If you open a pdf as a text file, you should be able to find catalog entries (they begin and end with "<<" and ">>" respectively.
On a simple pdf file, i found the following:
<</Type/Font/BaseFont/Helvetica-Bold/Subtype/Type1/Encoding/WinAnsiEncoding>>
thus searching for the prefix should help you (in some pdf files, there are spaces between
the commponents but '/Type /Font' should be ok).
Of course this is a manual process, while you would probably prefer an automatic one.
On another note, we sometime use identifont or what the font to find uncommon fonts that give us problem (logo font).

Edit : the following code will find all font in the pages. To be short, you search the dictionnary of each page for the subdictionnary "ressource" and then the subdictionnary "font". Each entry in the later is a font dictionnary, describing a font.
PdfReader reader = new PdfReader(
new FileInputStream(new File("file.pdf")));
int nbmax = reader.getNumberOfPages();
System.out.println("nb pages " + nbmax);
for (int i = 1; i <= nbmax; i++) {
System.out.println("----------------------------------------");
System.out.println("Page " + i);
PdfDictionary dico = reader.getPageN(i);
PdfDictionary ressource = dico.getAsDict(PdfName.RESOURCES);
PdfDictionary font = ressource.getAsDict(PdfName.FONT);
// we got the page fonts
Set keys = font.getKeys();
Iterator it = keys.iterator();
while (it.hasNext()) {
PdfName name = (PdfName) it.next();
PdfDictionary fontdict = font.getAsDict(name);
PdfObject typeFont = fontdict.getDirectObject(PdfName.SUBTYPE);
PdfObject baseFont = fontdict.getDirectObject(PdfName.BASEFONT);
System.out.println(baseFont.toString());
}
}
The name (variable "name" in the following code) is what is used in the text to change font. In the PDF, you'll have to find it next to a text. The following number is the size. Here for example, it's size 12. (sorry, still no code for this part).
BT
/F13 12 Tf
288 720 Td
the text to find Tj
ET
Depending on the PDF, if it hasn't been outlined you may be able to open it in Adobe Illustrator, double click the text and select some of it to see it's font family, size, etc.
If the text is outlined then use one of those online tools that PATRY suggests to find out the font.
Good luck
If you have Adobe Acrobat you can see the fonts inside and examine the objects and text streams. I wrote a blog post on this at http://pdf.jpedal.org/java-pdf-blog/bid/10479/Viewing-PDF-objects
