//it completely fit in view in uiview,pdf pages are get images in view
  CGPDFDocumentRef PDFfile;    
     CFURLRef pdfURL = CFBundleCopyResourceURL(CFBundleGetMainBundle(), CFSTR("iPhoneAppProgrammingGuide.pdf"), NULL, NULL);
                PDFfile = CGPDFDocumentCreateWithURL((CFURLRef)pdfURL);
                CFRelease(pdfURL);

            CGPDFPageRef page = CGPDFDocumentGetPage(PDFfile,currentpage);

            context = UIGraphicsGetCurrentContext();
            CGContextSaveGState(context);
            CGContextSetRGBFillColor(context, 1.0, 1.0, 1.0, 1.0);
            CGContextFillRect(context,self.bounds);   
            CGContextTranslateCTM(context, -1.0, [self bounds].size.height);
            CGContextScaleCTM(context, 1.0, -1.0);
            CGContextConcatCTM(context, CGPDFPageGetDrawingTransform(page,  kCGPDFArtBox, [self bounds], 0, true));
            CGContextDrawPDFPage(context, page);    
            CGContextRestoreGState(context);
            CGAffineTransform transform = aspectFit(CGPDFPageGetBoxRect(page, kCGPDFMediaBox),
                                                        CGContextGetClipBoundingBox(context));

               CGContextConcatCTM(context, transform);
                 UIGraphicsBeginImageContext(CGSizeMake(self.bounds.size.width, self.bounds.size.height));
