+## Introduction
+
+Stamp image repeatly on [canvas](canvas.md), similar with [TileSprite](tilesprite.md).  
+It has better rendering result when the texture size is not power of 2, in `WebGL` and `pixelArt` mode.

+## Usage
+
+[Sample code](https://github.com/rexrainbow/phaser3-rex-notes/tree/master/examples/repeat-image)
+
+### Install plugin
+
+#### Load minify file
+
+- Load plugin (minify file) in preload stage
+    ```javascript
+    scene.load.plugin('rexrepeatimageplugin', 'https://raw.githubusercontent.com/rexrainbow/phaser3-rex-notes/master/dist/rexrepeatimageplugin.min.js', true);
+    ```
+- Add repeat-image object
+    ```javascript
+    var image = scene.add.rexRepeatImage(x, y, width, height, key, frame);
+    ```
+
+#### Import plugin
+
+- Install rex plugins from npm
+    ```
+    npm i phaser3-rex-plugins
+    ```
+- Install plugin in [configuration of game](game.md#configuration)
+    ```javascript
+    import RepeatImagePlugin from 'phaser3-rex-plugins/plugins/repeatimage-plugin.js';
+    var config = {
+        // ...
+        plugins: {
+            global: [{
+                key: 'rexRepeatImagePlugin',
+                plugin: RepeatImagePlugin,
+                start: true
+            },
+            // ...
+            ]
+        }
+        // ...
+    };
+    var game = new Phaser.Game(config);
+    ```
+- Add repeat-image object
+    ```javascript
+    var image = scene.add.rexRepeatImage(x, y, width, height, key, frame);
+    ```
+
+#### Import class
+
+- Install rex plugins from npm
+    ```
+    npm i phaser3-rex-plugins
+    ```
+- Import class
+    ```javascript
+    import RepeatImage from 'phaser3-rex-plugins/plugins/repeatimage.js';
+    ```
+- Add repeat-image object
+    ```javascript    
+    var image = new RepeatImage(scene, x, y, key, frame, config);
+    scene.add.existing(image);
+    ```
+
+### Install plugin
+
+Install plugin in [configuration of game](game.md#configuration)
+
+```javascript
+var config = {
+    // ...
+    plugins: {
+        global: [{
+            key: 'rexRepeatImagePlugin',
+            plugin: RepeatImagePlugin,
+            start: true
+        },
+        // ...
+        ]
+    }
+    // ...
+};
+var game = new Phaser.Game(config);
+```
+
+### Create instance
+
+```javascript
+var image = scene.add.rexRepeatImage(x, y, width, height, key, frame);
+```
+
+Add image from JSON
+
+```javascript
+var image = scene.make.rexRepeatImage({
+    x: 0,
+    y: 0,
+    width: 512,
+    height: 512,
+    key: '',
+    
+    add: true
+});
+```
+
+### Custom class
+
+- Define class
+    ```javascript
+    class MyImage extends RepeatImage {
+        constructor(scene, x, y, width, height, key, frame) {
+            super(scene, x, y, width, height, key, frame);
+            // ...
+            scene.add.existing(this);
+        }
+        // ...
+
+        // preUpdate(time, delta) {}
+    }
+    ```
+    - `scene.add.existing(gameObject)` : Adds an existing Game Object to this Scene.
+        - If the Game Object renders, it will be added to the Display List.
+        - If it has a `preUpdate` method, it will be added to the Update List.
+- Create instance
+    ```javascript
+    var image = new MyImage(scene, x, y, width, height, key, frame);
+    ```
+
+### Set texture
+
+```javascript
+image.setTexture(key, frame);
+```
+
+### Properties of tiles
+
+- Position
+    ```javascript
+    image.setTilePosition(x, y);
+    ```
+    or
+    ```javascript
+    image.tilePositionX = x;
+    image.tilePositionY = y;
+    ```
+- Scale
+    ```javascript
+    image.setTileScale(scaleX, scaleY);
+    ```
+    or
+    ```javascript
+    image.tileScaleX = scaleX;
+    image.tileScaleY = scaleY;
+    ```
+
+### Other properties
+
+See [game object](gameobject.md)
+
+### Create mask
+
+```javascript
+var mask = image.createBitmapMask();
+```
+
+See [mask](mask.md)
+
+### Shader effects
+
+Support [preFX and postFX effects](shader-builtin.md)
+
+### Compare with [TileSprite](tilesprite.md)
+
+Using this RepeatImage when the texture size is not power of 2, in `WebGL` and `pixelArt` mode.  
+Otherwise, using [tileSprite](tilesprite.md)
