Properties

| Prop | Type | Description | | :---------------------- | :--------: | :------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | | style | object | Styles to be applied on canvas component | | strokeColor | string | Set the color of stroke, which can be #RRGGBB or #RRGGBBAA. If strokeColor is set to #00000000, it will automatically become an eraser. NOTE: Once an eraser path is sent to Android, Android View will disable hardware acceleration automatically. It might reduce the canvas performance afterward. | | strokeWidth | number | The thickness of stroke | | drawMode | string | Drawing mode: 'draw' for freehand drawing, or a shape type ('line', 'rectangle', 'circle', 'arrow'). Default is 'draw'. | | shapeFilled | boolean | Deprecated: Fill functionality has been removed as the component is optimized for outlining images. This prop has no effect. | | shapes | array | Array of shape objects to render on the canvas | | onStrokeStart | function | An optional function which accepts 2 arguments x and y. Called when user's finger touches the canvas (starts to draw) | | onStrokeChanged | function | An optional function which accepts 2 arguments x and y. Called when user's finger moves | | onStrokeEnd | function | An optional function called when user's finger leaves the canvas (end drawing) | | onShapeStart | function | An optional function which accepts 2 arguments x and y. Called when user starts drawing a shape | | onShapeChanged | function | An optional function which accepts 1 argument shape. Called when user is drawing a shape | | onShapeEnd | function | An optional function which accepts 1 argument shape. Called when user completes drawing a shape | | onTextTapped | function | An optional function which accepts 1 argument textId. Called when user taps on a text element. The text will be automatically selected for dragging | | onTextEditingComplete | function | An optional function which accepts 1 argument text. Called when text editing is completed | | pendingTextMode | boolean | When true, the next tap on the canvas will add a text element at that position. Default is false | | onTextPlaced | function | An optional function which accepts 1 argument position (an object with x and y coordinates). Called when a text is placed on the canvas in pendingTextMode | | onSketchSaved | function | An optional function which accepts 2 arguments success and path. If success is true, image is saved successfully and the saved image path might be in second argument. In Android, image path will always be returned. In iOS, image is saved to camera roll or file system, path will be set to null or image location respectively. | | onPathsChange | function | An optional function which accepts 1 argument pathsCount, which indicates the number of paths. Useful for UI controls. | | onShapesChange | function | An optional function which accepts 1 argument shapesCount, which indicates the number of shapes. Useful for UI controls. | | user | string | An identifier to identify who draws the path or shape. Useful when undo between two users | | touchEnabled | bool | If false, disable touching. Default is true. | | text | array | Array of text objects to render on the canvas. Each text object can include enhanced formatting options (see Text Properties) | | localSourceImage | object | Require an object (see below) which consists of filename, directory(optional) and mode(optional).

Background Image

To use an image as background, localSourceImage(see below) reqires an object, which consists of filename, directory(optional) and mode(optional). Note: Because native module cannot read the file in JS bundle, file path cannot be relative to JS side. For example, '../assets/image/image.png' will fail to load image.

Typical Usage

Load image from app native bundle
- Android:
  1. Put your images into android/app/src/main/res/drawable.

Performance

For non-transparent path, both Android and iOS performances are good. Because when drawing non-transparent path, only last segment is drawn on canvas, no matter how long the path is, CPU usage is stable at about 20% and 15% in Android and iOS respectively.
For transparent path, CPU usage stays at around 25% in Android, however, in iOS, CPU usage grows to 100%.
