我想在UIimage中添加模糊效果,而不是UIImage View。 我可以添加模糊效果到UIImage的观点 就像这样:如何使用Swift将模糊效果添加到UIImage中?
let blurEffect = UIBlurEffect(style: UIBlurEffectStyle.light)
let blurEffectView = UIVisualEffectView(effect: blurEffect)
blurEffectView.frame = img.bounds
blurEffectView.autoresizingMask = [.flexibleWidth, .flexibleHeight]
img.addSubview(blurEffectView)
但是,我真的很想加入到UIImage的。因为我必须用文字画图。所以这里是我的功能:
func textToImageWithPhoto(drawText text: NSString, inImage image: UIImage, atPoint point: CGPoint) -> UIImage {
let scale = UIScreen.main.scale
UIGraphicsBeginImageContextWithOptions(CGSize.init(width: 375, height: 375), false, scale)
image.draw(in: CGRect(origin: CGPoint.init(x: 0, y: -100), size: CGSize(width: 375, height: 375*1.5)))
let rect = CGRect(origin: CGPoint.init(x: 0, y: 187.5 - 150/2), size: CGSize.init(width: 375, height: 375))
text.draw(in: rect, withAttributes: textFontAttributes)
let newImage = UIGraphicsGetImageFromCurrentImageContext()
UIGraphicsEndImageContext()
self.saveData(img: newImage!, text: self.quotesTxt.text!) //SAVE CORE DATA
return newImage!
}
是否有某种方式来添加模糊效果内绘制函数?

在返回新图像的同时在图像上添加文本之后,在'blurredImage = UIImageEffects.imageByApplyingLightEffect(to:newImage)' –
@Mukesh之前执行此操作,但是,当添加模糊图像时,图像大小会发生变化!保持图像大小,我该如何解决它? –
