This is a simple cropper of images using SwiftUI. So you can customize the cropper easily and crop image in iOS/iPadOS even in macOS.
I make a demo in iOS/iPadOS to help you know how it works, and it also shows the size of image in pixel. It will show an image I inputted in advance. Then you can crop it in your mind, and touch the symbol "crop". The cropped image will show! It works like below in iPhone and iPad:
iPhone：
iPhone.mp4
iPad：
iPad.mov
You can follow the Usage to take SwiftUI_ImageCropper into your app or project! Enjoy it!
Copy or drag "CropperView" and "CropImage" to your project. (The package is developping, coming soon)
Then you can use following code to call it in any View:
CropperView(inputImage: UIImage, croppedImage: Binding<UIImage>, cropBorderColor: Color?, cropVerticesColor: Color, cropperOutsideOpacity: Double)
There are some parameters for you to customize or use the cropper(If you want more, please "issue" me):
| Parameter | Type | Default | Description |
|---|---|---|---|
| inputImage | UIImage | You must assign it | Image you want to be cropped |
| croppedImage | Binding | You must assign it | The cropped image(it need you create a UIImage first), you can show or save it |
| cropBorderColor | Color? | Color.white | As name said, it control the color of border of cropper |
| cropVerticesColor | Color | Color.pink | As name said, it control the color of Vertices of cropper |
| cropperOutsideOpacity | Double | 0.4 | The opacity of dark mask out of cropper |
There are some demoes to show the changes in order (Defult vs Changed).
cropBorderColor: Defult vs Color.yellow
cropVerticesColor: Defult vs Color.yellow
cropperOutsideOpacity: Defult vs 0.8
If you check the source code, you will find some issues "Invalid frame dimension (negative or non-finite)." Rest assured, they will not affect the operation.
If you find a bug, please report it!
