CropProperties class

The crop properties of an object enclosed in a container.

For example, an Image. The crop properties is represented by the offsets of four edges which define a crop rectangle. The offsets are measured in percentage from the corresponding edges of the object's original bounding rectangle towards inside, relative to the object's original dimensions. - If the offset is in the interval (0, 1), the corresponding edge of crop rectangle is positioned inside of the object's original bounding rectangle.

  • If the offset is negative or greater than 1, the corresponding edge of crop rectangle is positioned outside of the object's original bounding rectangle. - If the left edge of the crop rectangle is on the right side of its right edge, the object will be flipped horizontally. - If the top edge of the crop rectangle is below its bottom edge, the object will be flipped vertically. - If all offsets and rotation angle is 0, the object is not cropped. After cropping, the content in the crop rectangle will be stretched to fit its container.

Properties

angle double?
The rotation angle of the crop window around its center, in radians.
getter/setter pair
bottomOffset double?
The offset specifies the bottom edge of the crop rectangle that is located above the original bounding rectangle bottom edge, relative to the object's original height.
getter/setter pair
hashCode int
The hash code for this object.
no setterinherited
leftOffset double?
The offset specifies the left edge of the crop rectangle that is located to the right of the original bounding rectangle left edge, relative to the object's original width.
getter/setter pair
rightOffset double?
The offset specifies the right edge of the crop rectangle that is located to the left of the original bounding rectangle right edge, relative to the object's original width.
getter/setter pair
runtimeType Type
A representation of the runtime type of the object.
no setterinherited
topOffset double?
The offset specifies the top edge of the crop rectangle that is located below the original bounding rectangle top edge, relative to the object's original height.
