Creating a PDF section using a byte array

August 13, 2014, 6:17 am

Hello,

Im building a big pdf out of multiple sources including other PDFs, which are retrieved via API in the form of a byte array. Using Generator.Pdf.Import(streamreader) seems like it is built for that, but it is giving me a blank section every time.

Here is my code

                       MemoryStream mstream = new MemoryStream(pdfByteArray);                        Pdf pdf = new Pdf();                        pdf.Import(new StreamReader(mstream));                        Section section = new Section(pdf);

finalPdf.Sections.Insert(finalPdf.Sections.Count, section);

it is blank,  so perhaps this is not the proper way of doing it?
the documentation is light on this subject,  
http://www.aspose.com/docs/display/pdfnet/Import+Overload_1
so I hope you can help.

My name is Fabio Rosa.
I'm the develop manager of Industrial area of Fabril/Forwood System of the Lógica Informática company.
I tested the Aspose.PDF 9.5 to verify the issue correction.
The conversion work is better, but not perfect yet... In some cases, (and I don't know why) the blanks columns didn't respected yet.
Follow one example. Please, pay attention in 'Saldo Inicial' column, where the first value (13,0000) is in the erlier column... and on the ninth value either...

Would you adjust it?

Below is our code

ExcelSaveOptions options = new ExcelSaveOptions();

options.InsertBlankColumnAtFirst = false;

options.UniformWorksheets = true;

//options.MinimizeTheNumberOfWorksheets = true;

Document pdfDoc = new Document(_filePath);

var saveDialog = new SaveFileDialog();

var startIndex = _filePath.LastIndexOf(@"\") + 1;

var endIndex = _filePath.Length - startIndex - (_filePath.Length - _filePath.LastIndexOf('.'));

saveDialog.FileName = _filePath.Substring(startIndex, endIndex) + ".xls";

saveDialog.DefaultExt = ".xls";

saveDialog.Filter = "Pasta de Trabalho do Excel (agrupado)|*.xls|Pasta de Trabalho do Excel (páginas)|*.xls";

var result = saveDialog.ShowDialog();

(...)

pdfDoc.Save(saveDialog.FileName, options);

Hi,

I have a requirement to stamp an image to pdf document. I would like to place the stamp on a certain position in the pdf. The position of the stamp is captured from an image generated from the pdf and stored in our backend. How do I use that information in your Java APIs to exactly stamp at that position?

I've just downloaded the Java Components from the downloads page and got a .ZIP file.

I'm looking to start using the trial to convert text documents to PDFs however there's nothing in that .ZIP that tells me what purpose any of the files have. I see some JARs in there, but I'm not if they're there for developing or as part of the example.

Any help would be greatly appreciated.

Is it normal that Java Aspose library can not get attachements from a PDF document generated with Acrobat 11? (pdfDocument.getEmbeddedFiles().size() returns me 0 ). Or do I need an license to do this ? I'haven't got any evaluation License. How can I get one and how should I install It?

For example : For sample attached image, when the same image used to create 55 MultiPage PDF, it would create larger Multipage PDF.

Hi,

We have the issue while adding attachment into a PDF file by using FileSpecification with stream.

using (System.IO.Stream ms = ...)

{

pdf.EmbeddedFiles.Add(new FileSpecification(ms, file.ID));

}

The Modified date for the attachments added by this way is Unknown. Check attached image.

The problem is that we have this information and willing to update it. But

FileSpecification->FileParams.ModDate is the ReadOnly property.

How can we specify CreationDate, ModDate if we use FileSpecification stream constructor?

Dear Aspose,

I am having trouble specifying the default view for Pdf documents. I would like them all to open to fit the page width and open at the very start of the document i.e. top edge of first page.

This is the code I am using and while it zooms to the page width it does not start at the top of the document. Aspose.Pdf version 9.4.0.

Please help!

var pdfDocument = new Aspose.Pdf.Document(pdfDocumentStream);
pdfDocument.OpenAction = new GoToAction(new FitHExplicitDestination(pdfDocument.Pages[1], 0d));
pdfDocument.OptimizeResources(new Aspose.Pdf.Document.OptimizationOptions

PDF header signature not found

≫ Next: Questions about new PDF library

≪ Previous: Pdf Open Action default view

We are using another tool that creates an image from a scanner from our web application. That image is then passed from the client to the server and to our Aspose logic as a stream. Then we create an Aspose Pdf document from the stream, add a FreeTextAnnotation and save the file to disk. Out of the 4,000 or so documents we have created, around 10 have been corrupt and we are unable to open with Adobe reader for example. We did find that Chrome was able to view the documents though. After some debugging using itextsharp, we see the error PDF Header signature not found. When we open up the documents in notepad, the first few bytes look off. Generally the first few characters in the pdf file begin with something like “%PDF-1.6” (without the quotes). The corrupt files are missing the version number and look something like “%PDF “.

Just wondering if you have any ideas on why the files would be missing the needed header information. Aspose pdf was able to open up the corrupt files and then we copied the pages to a new pdf document and saved and everything is good.

Ok this will work without ERROR!
thx

but now I have some questions how I should to things with this code and the new PDF library

1. How can I set the PDF Conformance to PdfFormat.PDF_A_1B
2. How can I set the PDF to an A4 or an A3 Page size
3. How can I write a text with one or more rows over the picture (like watermarker) on the bottom corner centered or on the right corner centered?
4. How can I set the Font of the new text over my picture
5. I need to insert the picture in the A4 document without margin but also without fitting the image to the page, so if the original sized image fit into the page without resizing is ok, if not I have to resize the Image to 50% if now it fit into the page its OK, if not I have to do this severeal times! I hope I explained it ok!

≪ Previous: Questions about new PDF library

Hello,

I tried your sample code in C# "Adding Text Stamp in the PDF File":

//open document

Document pdfDocument = new Document("input.pdf");

//create text stamp

TextStamp textStamp = new TextStamp("Sample Stamp Polish Chars ęąśłóńźżć");

//set whether stamp is background

textStamp.Background = true;

//set origin

textStamp.XIndent = 100;

textStamp.YIndent = 100;

//set text properties

textStamp.TextState.Font = FontRepository.FindFont("Helvetica");

textStamp.TextState.FontSize = 14.0F;

textStamp.TextState.FontStyle = FontStyles.Italic;

textStamp.TextState.ForegroundColor = Aspose.Pdf.Color.FromRgb(System.Drawing.Color.Aqua);

//add stamp to particular page

pdfDocument.Pages[1].AddStamp(textStamp);

//save output document

pdfDocument.Save("output.pdf");

but with this differrence that I chose Helvetica font (core PDF font) and used Polish Characters in TextStamp. When I use Polish Characters in combination with Helvetica font the feature FontStyles.Italic dosen't work.

How to use Polish Characters or where can I change encoding?
