Detailed Description

An ImageDocument is the base class of the ImageEditor.

This class handles various image manipulation and contains an undo stack to allow reverting the last actions. This class does not display the image, use ImageItem for this task.

KQuickImageEditor.ImageDocument {
   id: imageDocument
   path: myModel.image
}
 
Kirigami.Actions {
   iconName: "object-rotate-left"
   onTriggered: imageDocument.rotate(-90);
}
 
KQuickImageEditor.ImageItem {
    image: imageDocument.image
}
