My code is as below. I get the error as
Assertion failed: (s->stack->next != NULL), function CGGStackRestore, file Context/CGGStack.c, line 116.
Code:
CGPDFPageRef page = CGPDFDocumentGetPage(document, i+1);
CGRect pageRect = CGPDFPageGetBoxRect(page, kCGPDFMediaBox);
CGFloat pdfScale = width/pageRect.size.width;
pageRect.size = CGSizeMake(pageRect.size.width*pdfScale, pageRect.size.height*pdfScale);
pageRect.origin = CGPointZero;
UIGraphicsBeginImageContext(pageRect.size);
CGContextRef context = UIGraphicsGetCurrentContext();
// White BG CGContextSetRGBFillColor(context, 1.0,1.0,1.0,1.0); CGContextFillRect(context,pageRect); CGContextSaveGState(context);
CGContextTranslateCTM(context, 0.0, pageRect.size.height);
CGContextScaleCTM(context, 1.0, -1.0);
CGContextConcatCTM(context, CGPDFPageGetDrawingTransform(page, kCGPDFMediaBox, pageRect, 0, true));
CGContextDrawPDFPage(context, page);
CGContextRestoreGState(context);
UIImage *thm = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
NSLog(@"Image %@",thm);
pdfImage = [[UIImageView alloc] initWithImage:thm];
NSLog(@"Image View: %@",pdfImage);
[self.view addSubview:pdfImage];
[self.view reloadInputViews
];
Please Help.
There is no CGContextSaveGState
before CGContextRestoreGState
!
