Iphone中的ImageMagick：如何在iphone中将Image对象转换为UIImage [英] ImageMagick in Iphone: how to convert Image object to UIImage in iphone

问题描述

我正试图在Iphone中使用imageMagick创建图像失真。
以下是我的代码：

I am trying to create a distortion in image using imageMagick in Iphone. Following is my code:

Image *img = GetImageFromMagickWand(magick_wand);
const double ctrlPts[8] = {150,150,50,50,10,20,90,10};
const size_t q = 4;
ExceptionInfo *d = AcquireExceptionInfo() ;
const RectangleInfo r = {10,10,5,4};
size_t my_size;
Image *distortedImage = DistortImage(img, AffineDistortion, q, ctrlPts, MagickTrue, d);

现在我在这里陷入困境。如何将这个distortedImage对象转换为UIImage对象，以便我可以使用该图像。

Now I am meshed over here. How to convert this distortedImage object to UIImage object so that I can use that Image.

推荐答案

NSData * data = [[NSData alloc] initWithBytes:distortedImage length:my_size];
free(distortedImage);
UIImage * image = [[UIImage alloc] initWithData:data];

如果您不知道尺寸，请尝试以下方法：

if you don't know the size try the following:

NSData *data = UIImagePNGRepresentation(initWithBytes:distortedImage);
free(distortedImage);
UIImage * image = [[UIImage alloc] initWithData:data];
