I am getting PdfError at "PdfString str1( ar.c_str() );": PoDoFo encountered an error. Error: 8 ePdfError_InternalLogic Error Description: An internal error occurred. Callstack: #0 Error Source: podofo/base/PdfString.cpp:171
My guess is that in order to join these characters you would need to do kerning (https://en.wikipedia.org/wiki/Kerning) or use ligatures/alternates (https://en.wikipedia.org/wiki/Orthographic_ligature). From my observation podofo does not support these things: https://sourceforge.net/p/podofo/mailman/message/36260915/ https://sourceforge.net/p/podofo/mailman/message/36683139/ >From what I googled indicates that seems truetype fonts do not support ligatures but opentype fonts do support them. And seems podofo does not support opentype fonts (also from my experience regarding font subsetting): https://sourceforge.net/p/podofo/mailman/message/21215446/ On Mon, Nov 18, 2019 at 8:50 AM Anand Ramasamy <ramasam...@hcl.com> wrote: > Dear All, > > > > Thanks in advance for the help. > > > > We are facing an issue with Arabic characters when using Podofo library to > draw it in PDF file. > > > > The characters are not joined together in the output pdf file. > > Below is the code that we have implemented to draw Arabic characters in > PDF file. > > > > Attached the expected output and actual output snapshots. > > > > Kindly let us know whether any other settings needs to be enabled or > should we use any other API. > > > > ... > > pFont = document->CreateFont("Arabic Typesetting", false, false, false, > PdfEncodingFactory::GlobalIdentityEncodingInstance(), > PoDoFo::PdfFontCache::eFontCreationFlags_None); > > painter.SetFont(pFont); > > ... > > wstring ar = L"ابناء الشيخ"; > > std::reverse(ar.begin(), ar.end()); > > PdfString str1( ar.c_str() ); > > PdfString pString = str1.ToUnicode(); > > > > painter.AddText(pString, pString.GetCharacterLength()); > > ... > > > > Below are our observations regarding this issue. > > 1.
