I got the following exception in itextsharp 5.0.6 library when I am trying to parse one PDF file Keep it 1 8 25.
IText Group NV Partner Member iText Group is a global leader in PDF technology, including iText 7 Suite and iText DITO. IText 7 Suite is a comprehensive open source PDF SDK which includes iText 7 Core and optional add-ons to give you the flexibility to fit your needs. IText 7 Core is a PDF library that you can build into your own applications and is a reimagining of the popular iText 5 engine. Changes in 1.2 1) Fixed size of windows to work with very low and very high resolutions. 2) More settings in Join PDF files option. Changes in 1.1 1) Allow multiple file selection in Join's File open dialog window 2) Added new feature to generate PDF from xml file. Please note JRE/JDK (version 1.4 or above) is required to run PDFTools.
here is the link of that PDF File https://backup.filesanywhere.com/fs/v.aspx?v=8c726b8f5a6673b56b6d
The content stream of the first page of the PDF contains an array start bracket '[' inside the array operand of a TJ operator. This is not allowed as the array operand of a TJ operator may only contain strings and numbers.
Furthermore there is no matching array end bracket ']' inside that array operand, so the end bracket of the array operand itself closes this (illegal) inner array and the array operand does not have a closing bracket anymore. Thus, iText parses all the remaining content stream into the array and at the end of the content stream runs into the exception.
Adobe Reader is well known to ignore certain errors and try to fix others on the run. Knowing that there are no nested arrays allowed in page content descriptions, it seems to simply ignore the illegal opening bracket. This behavior of Adobe Reader is quite a nuisance because it allows defect PDF creation software to flourish.
PS: The line in question:
