is there any other way using aspose.pdf to achieve this functionality
eg. create one blank pdf document and then copy each page from original file to newly created file
with some margin (eg. header height is 100px then we can copy page from old document and start it from 120px in new document)
We have create one web application, in .net and we need to do some manipulation in PDF while user upload pdf file before saving it on server.
Suppose i need to redact any information from Pdf then how can i do this.
our requirement is we remove email address from Pdf file and then we need to save it

Hi Jignesh,
Thanks for contacting support.
You may consider parsing the PDF document and try removing the email address information. May be you can use RegularExpression to search for email addresses or search for @ character and remove the text after it. For more information, please visit Replace Text Based on a Regular Expression
Hello,
is there any other way using aspose.pdf to achieve this functionalityeg. create one blank pdf document and then copy each page from original file to newly created filewith some margin (eg. header height is 100px then we can copy page from old document and start it from 120px in new document)Hi Jignesh,In order to accomplish above stated requirement, first you need to concatenate the pages of PDF files using Document class and then you can update page dimensions (to set new starting point for page contents), you can use ResizeContents(…) method of PdfFileEditor class. Please try using the following code snippet to accomplish this requirement. In case the problem still persists, please share the resource files which you are using so that we can test the scenario at our end.[C#]//open
first PDF document<o:p></o:p>Document pdfDocument = new Document("e:/pdftest/RotatedImage.pdf");
// open second PDF file
Document pdfDocument2 = new Document("e:/pdftest/TestPdf (1).pdf");
// add the pages of second PDF file to pages collection of first document
pdfDocument.Pages.Add(pdfDocument2.Pages);
//Create PdfFileEditor Object
PdfFileEditor fileEditor = new PdfFileEditor();
//Specify Parameter to be used for resizing
PdfFileEditor.ContentsResizeParameters parameters = new PdfFileEditor.ContentsResizeParameters(
//left margin = 10% of page width
PdfFileEditor.ContentsResizeValue.Percents(10),
//new contents width calculated automatically as width - left margin - right margin (100% - 10% - 10% = 80%)
null,
//right margin is 10% of page
PdfFileEditor.ContentsResizeValue.Percents(10),
//top margin = 10% of height
PdfFileEditor.ContentsResizeValue.Percents(10),
//new contents height is calculated automatically (similar to width)
null,
//bottom margin is 10%
PdfFileEditor.ContentsResizeValue.Percents(10)
);
//Resize Page Contents
fileEditor.ResizeContents(pdfDocument, new int[] { 2, 3 }, parameters);
//save document into new location.
pdfDocument.Save(“e:/pdftest/ContentsResized_output.pdf”);

Hi Jignesh,
Hello,
Please find attached files in which I perform replace some value. In this demo I replace year(xxxx-xxxx) fromat.
In Demo35 some information is removed. For reference I also attached generated file in zip.
In Demo32 value is not replace due to value is split in two rows.
Code :
//open document
Document pdfDocument = new Document(txtFilePath.Text);
//create TextAbsorber object to find all instances of the input search phrase
TextFragmentAbsorber textFragmentAbsorber = new TextFragmentAbsorber("\d{4}-\d{4}"); //like 1999-2000
//set text search option to specify regular expression usage
TextSearchOptions textSearchOptions = new TextSearchOptions(true);
textFragmentAbsorber.TextSearchOptions = textSearchOptions;
//accept the absorber for all the pages
pdfDocument.Pages.Accept(textFragmentAbsorber);
//get the extracted text fragments
TextFragmentCollection textFragmentCollection = textFragmentAbsorber.TextFragments;
//loop through the fragments
foreach (TextFragment textFragment in textFragmentCollection)
{
//update text and other properties
textFragment.Text = “xxxx-xxxx”;
//set to an instance of an object.
textFragment.TextState.Font = FontRepository.FindFont(“Calibri”);
//textFragment.TextState.FontSize = 22;
//textFragment.TextState.ForegroundColor = Aspose.Pdf.Color.FromRgb(System.Drawing.Color.Blue);
//textFragment.TextState.BackgroundColor = Aspose.Pdf.Color.FromRgb(System.Drawing.Color.Green);
}
pdfDocument.Save(txtNewFile.Text);
And also I need to apply same font and size as original text in PDF while replacing year with xxxx because of if font size of the text is less than which I used in above code then next statement is overwrite with replaced value(xxxx-xxxx)
And also let me know how I can remove mailto link from PDF Document.
Please reply ASAP.
Thanks,
Jignesh Chauhan

Hello,
When I am going to replace 10 digit with xxxxxxxxxx using below code. It is working properly if there is single occurrence of 10 digit but same code is not working if I keep 10 digit two times in line. For eg. If I keep 9898989898 it will replace with xxxxxxxxxx but when I keep this as 9898989898 / 1234567890 then code is replace only first occurrence (9898989898 is replaced) but 1234567890 is remains as it is.
I got same issue while replacing email address instead of 10 digit.
Code which I used is as Under
TextFragmentAbsorber textFragmentAbsorberForPhoneNumber = new TextFragmentAbsorber("\\d{10}"); //like 1999-2000
//set text search option to specify regular expression usage
textFragmentAbsorberForPhoneNumber.TextSearchOptions = textSearchOptions;
//accept the absorber for all the pages
pdfDocument.Pages.Accept(textFragmentAbsorberForPhoneNumber);
//get the extracted text fragments
textFragmentCollection = textFragmentAbsorberForPhoneNumber.TextFragments;
//loop through the fragments
foreach (TextFragment textFragment in textFragmentCollection)
{
//update text and other properties
textFragment.Text = "XXXXXXXXXX";
textFragment.TextState.ForegroundColor = Aspose.Pdf.Color.FromRgb(System.Drawing.Color.Black);
textFragment.TextState.BackgroundColor = Aspose.Pdf.Color.FromRgb(System.Drawing.Color.Black);
}
