Hello,
I add the picture to my pdf document using :
- (NSMutableData *)vAddImage:(NSData *)data withRect:(PDF_RECT)rect
( According to www.radaeepdf.com/forum/ios-dev/2580-how-to-add-a-picture )

Is there a way to get the full path of the document after saving the picture ? Or converting it to binary data(NSDATA )?

Thank you

Hi,

the path is the same used to open the pdf file.
You can get the file data using the contentsAtPath method of NSFileManager class.

Thank you for your prompt reply.

But when I called
NSData*pdfData = [[NSFileManager defaultManager]contentsAtPath:fullPath];
into the add Image method I get the pdf document without the new added image?
Thank you

is possible that your pdf is not in a writable directory?

Well the pdf is in a writable directory.But I am not sure if the image is saved properly or not.Here is my code.
That's how I call the add method :
- (NSData *)vAddImage:(NSData *)data withRect:(PDF_RECT)rect
{
   NSString *tp = NSTemporaryDirectory();
    tp = [tp stringByAppendingPathComponent:@"cache.dat"];
    [m_doc setCache:tp];
    PDFPage *page = [m_doc page:m_cur_page];
    CGImageRef ref = [UIImage imageWithData:data].CGImage;
    [page addAnnotBitmap:ref :NO :&rect];
    
    [m_view vRenderSync:m_cur_page];
    [self refresh];
    [m_doc save];
    NSData *pdfData = [[NSFileManager defaultManager]contentsAtPath: fullPath];
    return pdfData;

}

Please tell me;is there something missing in my code above for adding and saving the image into pdf?

You can try to check the save result with something like bool res = [m_doc save];
if the result is YES, the pdf is saved correctly.
Are you able to see the pdf page with the image after vAddImage method has been called?
