you can see which path i provided to the PDF by checking out the call to createPDFForBoard:atFilePath: as it is done in SudokuViewController class: NSArray *documentPaths = NSSearchPathForDirectoriesInDomains( NSDocumentDirectory, NSUserDomainMask, YES); NSString *file = [[documentPaths objectAtIndex:0] stringByAppendingPathComponent:"Sudoku.pdf"]; � [pdfCreator createPDFForBoard:dataController.board atFilePath:file]; I�m using the documents folder path for the app by calling NSSearchPathForDirectoriesInDomains, and then placing there a file named Sudoku.pdf in the first (and hopefully only) folder there (which is the documents folder). choose the �build phases� tab and open the �Copy Bundle Resources�. The items in Figure 14-1 are just a sample. Later just add the NSData object as an attachment with the right mime types, using addAttachmentData of the MFMailComposeViewController object. Add the universal libs to your app. .. If you do want to use customer streams, that�s possible too with StartPDFWithStream that accepts an IByteWriterWithPosition stream object. We did, however, find this program. ' where PDF operators and their descriptors are mixed with the actual PDF content. ..

NextPrevious Copyright 2001, 2014 Apple Inc. NextPrevious PDF Document ParsingQuartz provides functions that let you inspect the PDF document structure and the content stream. This site here has a good tutorial on how to do that for each of the libraries. The entries in the catalog recursively describe the contents of the PDF document. Stack Overflow Questions Jobs Documentation Tags Users Badges Ask Question Page Not Found We couldn't find the page you requested. Worry not, i�ll explain that too. If the document is encrypted, the code attempts to open is using a blank password. PDFHummus also requires doing this for the accompanying libraries � LibJpeg, LibTiff and Freetype. Terms of Use Privacy Policy Updated: 2014-09-17 . You can also pass any data that your callbacks need.Parses the content stream associated with the scanner.

drag the font file from the �supporting files� group to the �Copy Bundle Resources� area. for PDFHummus to work with it i needed a file. When you write your own code, youd look for the PDF operators appropriate for your application.Table 14-1Marked content operators represent some of the PDF operators that you can parse OperatorDescriptionMPA marked point that has a tag associated with it.DPA marked point that has a tag and a property list or object associated with it.BMCSignals the start of a marked-content sequence (begin marked content) and is paired with the EMC marker that signals the end of the sequence. The following sections show how to parse a content stream to find marked-content operators (see Table 14-1). Consult the PDF Reference for a complete list of PDF operators.You use a CGPDFScanner object ( CGPDFScannerRef data type) to parse a PDF content stream. To send a PDF as email attachment, use the following code (in SudokuViewController): if([MFMailComposeViewController canSendMail]){ MFMailComposeViewController *mail=[[MFMailComposeViewController alloc]init]; mail.mailComposeDelegate=self; [mail setSubject:"Look at my nice Sudoku Board!"]; NSData * pdfData = [NSData dataWithContentsOfFile:inPDFFilePath]; [mail addAttachmentData:pdfData mimeType:"application/pdf" fileName:"Sudoku.pdf"]; NSString * body = ""; [mail setMessageBody:body isHTML:NO]; [self presentViewController:mail animated:YES completion:nil]; } We�re using the MFMailComposeViewController to create a new mail, set the subject, add the PDF file as attachment and later display the email for further edit and sending. For example, the callback for the MP operator thats shown in Listing 14-2 calls the function CGPDFScannerPopName to retrieve the character string associated with the operator from the stack.

Check the code for this, it�s not PDF particular). An operator is specified as a tag that has a property list or an object associated with it. A property list is a dictionary that contains key-value pairs specified by the PDF content creator. The next step is to add the code to create (or parse) PDF files in the app itself. file contain its interface definition.
