We want to straighten a document placed diagonally. The technology to transform the image is amazing
It is a method of performing image transformation like a document scanner.
We want to cut out the documents straight we put.
If you place documents on your desk and shoot at an angle, it will move to a trapezoid.
To make this a straight rectangle, you need to deform the image.
DDPerspectiveTransform can be used
With the library, we can use a UI that allows you to easily format images manually.
How to use
Put the DDPerspectiveTransform in your project and display the UI.
It doesn’t have a crop button, so add a button and add a cropAction of the DDPerspectiveTransformViewController.
The formatted image can be received by the delegate.
The angle of the characters is also neatly shaped.
