Pdf settings

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)

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,

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”);

Hello,


I gone through example provided in link given by you, but getting some issue while replacing text.

1. Content after 1999-2005 are blank after replacing it with xxxx-xxxx. (e.g. paragarphs contains 1995-2005 in middle of the paragraph then all next statement after 1995-2005 are blank after executing code given in sample)
2. If Content is wrap in next line then it is not replace with xxxx-xxxx eg. 1999- in first line and then due to no much space in same line 2005 are wrap in next line then this code is not working.
3. First case working fine if we put this line in table.

Please reply as soon as possible

Thanks,

Hi Jignesh,


Can you please share the source PDF file along with code snippet which you are using so that we can test the scenario at our end.

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

Hi Jignesh,

Thanks for sharing the resource files.

I have tested the scenario and have noticed that above stated issue occurs when using the API in trial mode. The problem does not appear when using a valid license. For your reference, I have also attached the resultant PDF generated over my end.

tatvasoft2014:

I have tested the scenario and I am able to
notice the same problem. For the sake of correction, I have logged this problem
as PDFNEWNET-36746 in our issue tracking system.

When using the valid license, you can get the font size and name information and use the same information while replacing the text.

You may consider setting the link target to null. Please follow the instructions specified over Update Links in a PDF File. In case the problem still persists, please share the sample PDF file. We are sorry for your inconvenience.

Hi Jignesh,


Please follow the instructions specified over following link for further details on how to Get a temporary license

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);

}


Please reply ASAP.

Hi Jignesh,


Thanks for your inquiry. I am afraid while testing the scenario with Aspose.Pdf for .NET 9.1.0, we are unable to replicate the issue. Please download and try latest version of Aspose.Pdf for .NET, it will fix the issue. If issue persist then we will appreciate if you please share a console application to help reproduce the issue for further investigation.

We are sorry for the inconvenience caused.

Hello,


Thanks for sharing new Dll. I check and it works fine. Still I have one more question regarding PDF. How can I disable all links from PDF document.

Please find attached pdf file for sample. In this PDF I have added one link, and I dont want to allow user to click on that link and open URL. I Check this with below code but it is not working.

Code :
----------------------------
string urlPattern = @“http(s)?://([\w-]+.)+[\w-]+(/[\w- ./?%&=]*)?”;
foreach (Aspose.Pdf.Page page in pdfDocument.Pages)
{
//LinkAnnotation linkAnnot = (LinkAnnotation)pdfDocument.Pages[1].Annotations[1];
foreach (LinkAnnotation linkAnnot in page.Annotations)
{
Regex rgxURL = new Regex(urlPattern);
if (rgxURL.IsMatch(((Aspose.Pdf.InteractiveFeatures.GoToURIAction)(linkAnnot.Action)).URI))
{
page.Annotations.Delete(linkAnnot);
}
}
}

Please reply ASAP.

Thanks,

Jignesh Chuahan.

Hi Jignesh,


Thanks for your inquiry. Please check following code snippet to set empty URI for the link. Hopefully it will help you to accomplish the task.

// load the PDF
file
<o:p></o:p>

Document doc = new Document(myDir + "Web+URL.pdf");

// get the first link annotation from first page of document

LinkAnnotation linkAnnot = (LinkAnnotation)doc.Pages[1].Annotations[1];

// Modification link: change link URI

GoToURIAction goToAction = (GoToURIAction)linkAnnot.Action;

// specify the URI for link object

goToAction.URI = String.Empty;

// save the document with updated link

doc.Save(myDir+"PDFLINK_Modified_output.pdf");

Please feel free to contact us for any further assistance.


Best Regards,

Dear
Tilal Ahmad


I have also tried above sample code, but if We set goToAction.URI = string.empty then it is not open current URL but user is able to click on that link and new window of browser is opened. So need to disable that link not want to set action to blank, because while I set action to blank then it is open blank page in browser.

In my previous post I gave you sample code which I used but that code is working in case of I am updating the text (e.g. In document Url is www.aspose.com when I replace this URL with xxxxxxxxx and execute that code then it works fine.)

- OR -

Is there any way to remove all the hyperlinks from the document.

Thanks,

Jignesh Chauhan

Hi Jignesh,

Thanks for sharing the details.

I am afraid the current release of Aspose.Pdf for .NET does not support the feature to remove hyperlinks from PDF file. However for the sake of correction, I have logged this requirement in our issue tracking system as PDFNEWNET-36764. We will investigate this issue in details and will keep you updated on the status of a correction.

We apologize for your inconvenience.
