iOS - UIImage creating a blurry image

Question

I am creating an image with UIImage, and overlaying some text on top.

The end result is coming out blurry, and I want it to be clear

UIImage* DrawTextOnImage(NSString *text, UIImage *image)

{
    UIGraphicsBeginImageContextWithOptions(image.size, YES, 0.0);

    [image drawInRect:CGRectMake(0, 0, image.size.width, image.size.height)];
    CGRect rect = CGRectMake(10, 50, image.size.width-20, image.size.height-60);

    NSMutableParagraphStyle *paragraph = [[NSParagraphStyle defaultParagraphStyle] mutableCopy];
    paragraph.lineBreakMode = NSLineBreakByWordWrapping;
    paragraph.alignment = NSTextAlignmentCenter;

    NSShadow *shadow = [NSShadow.alloc init];
    shadow.shadowColor = [UIColor clearColor];

    NSDictionary *attributes = @{NSForegroundColorAttributeName:[UIColor whiteColor], NSFontAttributeName:[UIFont systemFontOfSize:18], NSParagraphStyleAttributeName:paragraph, NSShadowAttributeName:shadow};

    [text drawInRect:CGRectIntegral(rect) withAttributes:attributes];

    UIImage *newImage = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();

    return newImage;
}

I have seen others having problems when setting the scale wrong, but changing it doesn't affect mine. Anyone else having similar issues?

That question looks like it wants it to be blurry. I want it to be clear — mwiggs, Sep 07 '14 at 20:21
Can you post an image? It’s hard to say what the problem is without seeing it. — Zev Eisenberg, Sep 08 '14 at 01:36
Also, why are you adding a shadow with a clear color? Why not just omit the shadow? — Zev Eisenberg, Sep 08 '14 at 01:37
I can't post images as I don't have a reputation higher than 10. I have tried with and without the shadow, it makes no difference. I posted the image here [link](http://i62.tinypic.com/11ift03.jpg) — mwiggs, Sep 08 '14 at 22:05
