Add Text to the Image

HI

Im currently developing an application where i have to add the text over the image at any position in the image(not subview) and the output should开发者_StackOverflow be the single image file with the original image and the text embedded in it,any help will be appreciable.

eg : water mark on the image

Thanks sivasankar

UIImage *myImage = loadUnwatermarkedImage();
NSString *myWatermarkText = @"Watermark";
UIImage *watermarkedImage = nil;

UIGraphicsBeginImageContext(myImage.size);
[myImage drawAtPoint: CGPointZero];
[myWatermarkText drawAtPoint: CGPointMake(10, 10) withFont: [UIFont systemFontOfSize: 12]];
watermarkedImage = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();

Upon completion the watermarkedImage will be an autoreleased watermarked image. loadUnwatermarkedImage() is a fictional function providing an original image.
