Inconsistencies in extracting text from a PDF file

[Jesús]

Hi:

I am performing a series of tests extracting text from a PDF document. I have found a possible problem in the following lines:

            // Create a list to store the text data

            List<TextData> textDataCollection = new List<TextData>();

            //Extract text and get the text data

            string extractedText = loadedPage.ExtractText(out textDataCollection);

The extractedText string contains all the text on the page, however the textDataCollection the text is incomplete, mainly in the central part of the page. The project and the pdf file are attached.

Additionally, I have observed that the "y" is repeated in the extracted text string. highlighted in bold and underlined

Thank you

nosolvidaría en muchos años (es posible que nunca), y encima habríamos disfrutadode todo el tiempo empleado en cada una de las visualizaciones. Esta es la razónpor la que este curso tiene un guión muy progresivo, fácil de seguir, yy está

óptimamente distribuido durante días sucesivos. Su contenido creará sólidas

bases de conocimiento y nos permitirá avanzar con rapidez sin tener ninguna

sensación de dificultad. En vez de ver la misma película varias veces seguidas,vamos a ver una serie cuya trama bien entrelazada nos aportará mucha mayor«cultura cinéfila». En el aprendizaje hay que repartir tareas yy saber dejar cosaspara mañana, pero ojo, también hay que ser muyy constantes si queremos tener

éxito.Como en mis libros anteriores, el lector podrá encontrar aquí las tablas devocabulario completamente traducidas y asociadas. yEn ellas se incluyyen lostérminos en español y alemán, la pronunciación figurada de cada palabra

(my apologies for the Spanish text)

Thank you

Regards,

Jesús

Hi Jesus,

We have included the fix for the reported issue “Text cut down issue occurs while extracting the text from the PDF document" in our weekly release (v28.1.38). Please use the below link to download our latest NuGet.

 

https://www.nuget.org/packages/Syncfusion.Pdf.WinForms/28.1.38

 

Root cause:

The input document contains escape sequences in the content. It is not handled properly to skip the escape sequence and causes invalid index. It leads to the issue and draws with cut down content.
