x: number;

property y

y: number;

interface PercentCrop

interface PercentCrop extends Crop {}

property unit

unit: '%';

property ariaLabels

ariaLabels?: {
    cropArea: string;
    nwDragHandle: string;
    nDragHandle: string;
    neDragHandle: string;
    eDragHandle: string;
    seDragHandle: string;
    sDragHandle: string;
    swDragHandle: string;
    wDragHandle: string;
};

An object of labels to override the built-in English ones

property aspect

aspect?: number;

The aspect ratio of the crop, e.g. 1 for a square or 16 / 9 for landscape.

property children

children?: default_2.ReactNode;

The elements that you want to perform a crop on. For example an image or video.

property circularCrop

circularCrop?: boolean;

Show the crop area as a circle. If your aspect is not 1 (a square) then the circle will be warped into an oval shape. Defaults to false.

property className

className?: string;

Classes to pass to the ReactCrop element.

property crop

crop?: Crop;

Since v10 all crop params are required except for aspect. Omit the entire crop object if you don't want a crop. See README on how to create an aspect crop with a % crop.

property disabled

disabled?: boolean;

If true then the user cannot resize or draw a new crop. A class of ReactCrop--disabled is also added to the container for user styling.

property keepSelection

keepSelection?: boolean;

If true is passed then selection can't be disabled if the user clicks outside the selection area.

property locked

locked?: boolean;

If true then the user cannot create or resize a crop, but can still drag the existing crop around. A class of ReactCrop--locked is also added to the container for user styling.

property maxHeight

maxHeight?: number;

A maximum crop height, in pixels.

property maxWidth

maxWidth?: number;

A maximum crop width, in pixels.

property minHeight

minHeight?: number;

A minimum crop height, in pixels.

property minWidth

minWidth?: number;

A minimum crop width, in pixels.

property onChange

onChange: (crop: PixelCrop, percentageCrop: PercentCrop) => void;

A callback which happens for every change of the crop. You should set the crop to state and pass it back into the library via the crop prop.

property onComplete

onComplete?: (crop: PixelCrop, percentageCrop: PercentCrop) => void;

A callback which happens after a resize, drag, or nudge. Passes the current crop state object in pixels and percent.

property onDragEnd

onDragEnd?: (e: PointerEvent) => void;

A callback which happens when a user releases the cursor or touch after dragging or resizing.

property onDragStart

onDragStart?: (e: PointerEvent) => void;

A callback which happens when a user starts dragging or resizing. It is convenient to manipulate elements outside this component.

property renderSelectionAddon

renderSelectionAddon?: (state: ReactCropState) => default_2.ReactNode;

Render a custom element in crop selection.

property ruleOfThirds

ruleOfThirds?: boolean;

Show rule of thirds lines in the cropped area. Defaults to false.

property style

style?: default_2.CSSProperties;

Inline styles object to be passed to the ReactCrop element.

interface ReactCropState

interface ReactCropState {}

property cropIsActive

cropIsActive: boolean;

property newCropIsBeingDrawn

newCropIsBeingDrawn: boolean;

Type Aliases
