   Hi there! 😄

   My library is just merely a thin wrapper of libHaru, so I guess something is wrong with your usage of libHaru API. Here's a simple tutorial of libHaru usage:
   http://libharu.sourceforge.net/how_to_use.html

   As far as I can see, you may just call HPDF_AddPage() each time after you have drawn your page content, like this:

   // Create a data context
   PDFService_userData userData;
   HPDF_Doc pdf = HPDF_New(PDFService_defaultErrorHandler, &userData);
   userData.pdf = pdf;
   userData.service = self;
   userData.filePath = filePath;
   
   // Add page 1
   LOG(@"[libharu] Adding page 1");
   HPDF_Page page1 = HPDF_AddPage(pdf);
   LOG(@"[libharu] SetSize page 1");
   HPDF_Page_SetSize(page1, HPDF_PAGE_SIZE_A4, HPDF_PAGE_LANDSCAPE);
   
   // Draw something in page 1...
   // After you're done
   
   // Add page 2
   LOG(@"[libharu] Adding page 2");
   HPDF_Page page2 = HPDF_AddPage(pdf);
   LOG(@"[libharu] SetSize page 2");
   HPDF_Page_SetSize(page2, HPDF_PAGE_SIZE_A4, HPDF_PAGE_LANDSCAPE);
   
   // And draw something in page 2...
   // and so on...
   // Once you're done drawing all pages you need, then
   
   // Save the drawn PDF file to a specified path
   pathCString = [filePath cStringUsingEncoding:1];
   LOG(@"[libharu] SaveToFile filePath:%@\n pathCString:%s", filePath, pathCString);
   HPDF_SaveToFile(pdf, pathCString);
   
   

   ...but something could be wrong. Would you mind copy&paste your code here so I can consult further?
