iTextSharp.LGPLv2.Core

iTextSharp.LGPLv2.Core is an unofficial port of the last LGPL version of the iTextSharp (V4.1.6) to .NET Core.

Install via NuGet

To install iTextSharp.LGPLv2.Core, run the following command in the Package Manager Console:

PM> Install-Package iTextSharp.LGPLv2.Core

You can also view the package page on NuGet.

Linux (and containers) support

The SkiaSharp library needs extra dependencies to work on Linux and containers. Please install the following NuGet packages:

PM> Install-Package SkiaSharp.NativeAssets.Linux.NoDependencies
PM> Install-Package HarfBuzzSharp.NativeAssets.Linux

You also need to modify your .csproj file to include some MSBuild directives that ensure the required files are in a good place. These extra steps are normally not required but seems to be some issues on how .NET loads them.

<Target Name="CopyFilesAfterPublish" AfterTargets="AfterPublish">

FAQ

The pdf is created, but when I try to view it, it says that the document is in use by another process.

You should dispose the FileStream/MemoryStream explicitly. It won't be closed and disposed automatically at the end.

I can't find what would be the equivalent of the PdfTextExtractor class.

PdfTextExtractor exists in v5.0.2+ with AGPL license (Current project is based on the iTextSharp 4.x, not 5.x).

It can't display Unicode characters.

You can find more samples about how to define and use Unicode fonts here.

Table rowspans don't work correctly.

This version which is based on iTextSharp V4.1.6 doesn't support rowspans correctly (iTextSharp supports row spans correctly since v5.4.3, not before that). A solution based on the current version: use nested tables to simulate it.

iTextSharp.text.html.simpleparser.HTMLWorker does not exist.

It has been renamed to HtmlWorker.

Licensing

You have three license choices when it comes to iTextSharp: LGPL/MPL, AGPL, or a commercial license. The LGPL/MPL license is only an option with the older 4.1.6 version (used here). After that version, they switched to a dual AGPL/Commercial.

If you need a more recent version, you either have to make your project open-source or pay the license fee.

Hi,
I have multipage PDF files. I try to read page by page and get each page data as byte array to save as jpeg files. However, I couldn't find out why I am getting Parameter is not valid exception.
Here is my sample code.
Could you please about my issue? How can I save my each page of pdf as a jpg file.
Note: My test pdf file contains only images.
Thanks!

Document in use until .net process is ended

I'm having an issue where when I create a document in a .net core web app. The pdf is created, but when I try to view it is says that the document is in use by another process. I have to stop my web app in order to see the created pdf. I've been using itextsharp for years and in my old version I didn't have this issue.
Below is some code i'm using to create the pdf.

var document = new Document();
PdfWriter.GetInstance(document, new FileStream(path + "\\" + lastName + ", " + firstName + " " + todaysDate + ".pdf", FileMode.Create));
document.Open();

Do some work on document (code omitted for brevity)

document.Close();

Multiple fonts not working in Phrase

Summary of the issue

I have added multiple TTF fonts to font factory. When adding a phrase I have two blocks of text in two separate chunks added to the phrase, each of these chunks has a different font (retrieved from the font factory) when rendering the text all looks exactly the same.

Environment

The in-use version: v1.5.0
Operating system: macOS
IDE: Visual Studio Code
Language: C# / dotnet core 2.2

Example code/Steps to reproduce:

Apologies for some of the method calls here, but this is what I am using to detect a change in font (between runs) and if it is different alter it.

I can see that the new font is being successfully retrieved from the font factory, and I can see it being correctly added to the chunk. I have checked the font files and the fonts are noticeably different to look at (one being a lot thinner) but when it is rendered it is all the same (with what appears to be the original font)

FontFactory.Register("Fonts/TTF/Swis721-BT.ttf", "SWIS721-BT");
FontFactory.Register("Fonts/TTF/Swis721-Thin-BT.ttf", "SWIS721-THIN-BT");

...

foreach (var run in textElement.Runs)
{
    var runFont = originalFontFromFactory;
    if(run.FontFamily != textElement.FontFamily && !String.IsNullOrEmpty(run.FontFamily))
    {
        runFont = FontFactory.GetFont(FontNameConvertor.GetAliasForMapItemFont(run.FontFamily), textElement.FontSize + (adjustment.IncreaseFont + increaseFont))
    }
    var chunk = new Chunk($"\u00A0{run.Text}\u00A0", runFont);
    phrase.Add(chunk);
}

Output:

System.Drawing.Common dependency problem

An assembly specified in the application dependencies manifest (*.deps.json) was not found:
package: 'System.Drawing.Common', version: '4.5.0-preview1-25914-04'
path: 'lib/netcoreapp2.0/System.Drawing.Common.dll'

must removing System.Drawing.Common from *.deps.json then solved.

PdfPTable is throwing an Error when creating new page

Summary of the issue

When creating a new page which clones rows from the previous page I'm getting an exception from the RowSpanAbove in PdfPTable class.

Example code/Steps to reproduce:

From the looks of things this is because my header rows which I'm duplicating are using merging which causes the code to get confused. I had look in the PdfPTable class and there this line of code (Line: 1361) which checks the aboveCell isn't null and then get's the next cell.

  if (aboveCell == null)
            {
                int col = currCol - 1;
                aboveCell = aboveRow.GetCells()[col];
                while ((aboveCell == null) && (row > 0))
                    aboveCell = aboveRow.GetCells()[--col];
                return aboveCell != null && aboveCell.Rowspan > distance;
            }

This should work but clearly the while statement is checking the row hasn't gone below 0 not the column. Simple fix this while statement should be (col > 0) not row

  if (aboveCell == null)
            {
                int col = currCol - 1;
                aboveCell = aboveRow.GetCells()[col];
                while ((aboveCell == null) && (col > 0))
                    aboveCell = aboveRow.GetCells()[--col];
                return aboveCell != null && aboveCell.Rowspan > distance;
            }

Compatibility of PdfStamper

Summary of the issue

When I tried to modify acrofields of a non-English pdf. I found that I cannot save the pdf file. It stuck at the PdfStamperImp.cs Line 892. The program stopped but did not throw any exception. The pdf was created from a Microsoft Word document by Phantom PDF.

Then I tried a different version of PDF, PDFs directly produced by Microsoft Word are normal. The altMetadata seemed to be different in Phantom PDF.

   at iTextSharp.text.pdf.PdfDocument.Add(IElement element)
   at iTextSharp.text.Document.Add(IElement element)

Fix:

We cloned the project and debugged it in order to find why we're getting this error.
We found that the problem is at line 1365 of PdfPTable class:

while ((aboveCell == null) && (row > 0))
{
aboveRow = (PdfPRow)rows[--row];
aboveCell = aboveRow.GetCells()[currCol];
}

We did a modification in the while to handle aboveRow object in case it would be null:

while ((aboveCell == null) && (row > 0))
{
aboveRow = (PdfPRow)rows[--row];
if (aboveRow == null) return false;
aboveCell = aboveRow.GetCells()[currCol];
}

With this modification the component worked like a charm.

It would great if you can include this modification in the future releases of the component.
I also should mention that you did a good job porting iTextSharp to .NET core.

Hi,

I was trying to use your project for my .NetCore app, to replace the usage of the .net 4.0 lib which I can't use.

I managed to create the PdfReader, but I can't find what would be the equivalent of PdfTextExtractor class, do you have any idea?

Encoding problem with extracted text from Ghostscript generated pdf

Summary of the issue

Hi there,

We've been using this library for a long time now in order to extract text from pdfs. However, since we've switched methods for generating the input pdfs, the resulting extracted text is nothing but gibberish. To me it looks like an interesting encoding problem :)

I've compared the extracted text with another pdf library called PdfPig which extracts the text as expected. However, for performance reasons, iTextSharp is still the prefered option.

To debug the problem, I've looked at the differences in the tokenization code. Here you can find it in the alternative implementation. Certain parts look very familiar, but I noticed that PdfPig also corrects for endianness. I've reimplemented that in the PrTokenizer, but that didn't seem to be the solution.

We would really appreciate it if you could help us find a solution. Thanks!

Environment

The in-use version: 1.5.1
Operating system: Windows
IDE: VS2019

Example code/Steps to reproduce:

• sample-original.pdf This is the original file, where text extraction works in both methods.
• sample-recostar.pdf This is the file after it's gone through OCR software (I think it uses Ghostscript to generate the pdf).

            var fileNames = new[]
            {

                "sample-recostar.pdf"
            };

            ExtractWithItext(fileNames);
            ExtractWithPdfPig(fileNames);

            Console.ReadLine();
        }

        public static void ExtractWithItext(IEnumerable<string> fileNames)
        {
            Console.WriteLine($"ITEXT");
            foreach (var fileName in fileNames)
            {
                var reader = new iTextSharp.text.pdf.PdfReader(fileName);

                Console.WriteLine($"OUTPUT {fileName}: ");

                var content = reader.GetPageContent(1);

                var tokenizer = new iTextSharp.text.pdf.PrTokeniser(new iTextSharp.text.pdf.RandomAccessFileOrArray(content));
                while (tokenizer.NextToken())
                {
                    if (tokenizer.TokenType == iTextSharp.text.pdf.PrTokeniser.TK_STRING)
                    {
                        Console.Write(tokenizer.StringValue);
                    }
                }

                Console.WriteLine();
            }
        }

        private static void ExtractWithPdfPig(IEnumerable<string> fileNames)
        {
            Console.WriteLine($"PDFPIG");
            foreach (var fileName in fileNames)
            {
                Console.WriteLine($"OUTPUT {fileName}: ");
                using(var stream = File.OpenRead(fileName))
                using (UglyToad.PdfPig.PdfDocument document = UglyToad.PdfPig.PdfDocument.Open(stream))
                {
                    var page = document.GetPage(1);

                    string fullText = string.Join(" ", page.GetWords());

                    Console.WriteLine(fullText);

                }
            }

PdfContentByte.ShowTextAligned rotation is ignored

There is a bug in PdfContentByte.showTextAligned method. It goes like this:

if (rotation.ApproxNotEqual(0)) {
    // branch which assumes rotation is 0    
}
else {
    // branch which assumes rotation is not 0
}

So rotation is effictively ignored, because branches are switched. Changing that to

if (rotation.ApproxEquals(0)) {

} else {

}

fixes the issue.

Strong name missing warning

Summary of the issue

When used in VS2017 and Nuget after rebuild it warn:

Severity Code Description Project File Line Suppression State
Warning CS8002 Referenced assembly 'iTextSharp.LGPLv2.Core, Version=1.4.4.0, Culture=neutral, PublicKeyToken=null' does not have a strong name. Sestavy D:\Pracovni\git-repos\Lezeni-Core\Sestavy\CSC 1 Active

It is possible build it with strong name. We want replace are locally referenced downloade original dll with nuget version and in future switch to .netstandard and core.

Thanks for answer and migration of this LGPL version.

PdfTextExtractor

Hello! I'm currently using itextsharp 5.+ on my application, but I would like to port it to work in ASP.NET Core 2.0. The functionality I'm using right now is provided by PdfTextExtractor and related classes.

By now, the only migration project I've found is this, but it's 4.x. Do you have plans to upgrade it?

Thanks!

Newlines being ignored

Summary of the issue

I cannot get text to manually break to a new line within "columnText.SetSimpleColumn" I have added a new chunk with just "\n" in it, I have manually stripped out "\n" from my text and added a Chunk.NewLine, it seems to be ignoring my \n and any attempt to break onto a new line. The break characters are not displayed however, so they are being stripped out or processed somehow.

All my text is wrapping on top of itself as well. While it's unreadable, it might be 'breaking' but not moving down a line, however I can't find a way to fix it.

Environment

The in-use version: v1.5.0
Operating system: macOS
IDE: Visual Studio Code
Language: C# / dotnet core 2.2

Example code/Steps to reproduce:

NB: the unicode chars "\u00A0" are added to add a space before/after the text that doesn't get stripped out, but with/without this is makes no difference.

var ct = new ColumnText(cb);
var paragraph = new Paragraph();

var listofstrings = new List<string>();
listofstrings.Add("Some text that should \n break there \n and here");
foreach (var astring in listofstrings)
{
    var chunk = new Chunk($"\u00A0{astring}\u00A0", font);
    paragraph.Add(chunk);
}

ct.SetSimpleColumn(paragraph, ll_x, ll_y, ur_x, ur_y, 0, textElement.TextAlignment);
var status = ct.Go();

Output:

As you can see in the above picture, the text just wraps ontop of itself.

Any support for fdfWriter.SetFieldAsImage() ?

Summary of the issue

Previously in iTextSharp we were able to add images for image fields in FdfWriter like so:

//Add barcode image
Image img = Image.GetInstance(barcode_jpg);
fdfWriter.SetFieldAsImage("Barcode", img);
fdfWriter.Write();

Is there a way to do this with the .Net Core port that i am not seeing?
Thanks in advance.

Environment

Khmer Unicode is not rendering properly

I follow the step to create pdf succesfully and dispalyed the khmer text . but not proper rendering. And Lost English text.

private Font GetFont(string fontNameWithExtension, int fontSize = 12)
      {
          // string fontLocation = $"{Directory.GetCurrentDirectory()}{"/wwwwroot/fonts/" + fontNameWithExtension}";
          string path = _webHostEnviroment.WebRootPath + "/fonts";
          string fontPath = Path.Combine(path, fontNameWithExtension);

          iTextSharp.text.FontFactory.Register(fontPath);

          BaseFont bf = BaseFont.CreateFont(fontPath, BaseFont.IDENTITY_H, BaseFont.EMBEDDED);
          Font f = new Font(bf, fontSize);
          


          return f;

Example code/Steps to reproduce:

dotent test will throw an exception because of windows '\' directory separator characters.

 Test method iTextSharp.LGPLv2.Core.FunctionalTests.XmlITextTests.Verify_iTextXML_To_PDF_File_CanBeCreated threw exception: 
System.IO.DirectoryNotFoundException: Could not find a part of the path '/Users/breiter/src/vahidn/iTextSharp.LGPLv2.Core/src/iTextSharp.LGPLv2.Core.FunctionalTests/iTextExamples\resources\img/hitchcock.png'.

Solution: replace "iTextExamples\resources\img" with individual strings for each directory name and allow Path.Combine() to choose the appropriate Path.DirectorySeparatorChar for the OS.
