+### Canvas
+
+<sup>[API method description.](https://2captcha.com/2captcha-api#canvas)</sup>
+
+The canvas method can be used when you need to draw a line around an object on an image. Returns a set of points' coordinates to draw a polygon.
+
+```js
+solver.canvas({
+    body: 'iVBORw0KGgoAAAANSgAAAcIA...',
+    imginstructions: '/9j/4AAQSkZJRgABAQEA...',
+    textinstructions: 'Highlight the red CIRCLE'
+})
+.then((res) => {

+})
+.catch((err) => {
+    console.log(err);

+ * 
+ * This method can be used to bypass tasks in which you need to circle an object or line in an image.
+ * 
+ * @param {{ body, textinstructions, imginstructions, canSkip, lang, pingback}} params Parameters Canvas as an object.
+ * @param {string} params.body `Base64`- encoded captcha image.
+ * @param {string} params.textinstructions Text will be shown to worker to help him to select object on the image correctly. For example: "*Select cars in the image*". **Optional parameter**, if the instruction already exists in the form of the `imginstructions`. 
+ * @param {string} params.imginstructions Image with instruction for worker to help him to select object on the image correctly. The image must be encoded in `Base64` format. **Optional parameter**, if the instruction already exists in the form of the `textinstructions`.
+ * @param {number} params.canSkip Set the value to `1` only if it's possible that there's no images matching to the instruction. We'll provide a button "No matching images" to worker and you will receive `No_matching_images` as answer.
+ * @param {string} params.lang Language code. [See the list of supported languages](https://2captcha.com/2captcha-api#language).
+ * @param {string} params.pingback params.pingback URL for pingback (callback) response that will be sent when captcha is solved. URL should be registered on the server. [More info here](https://2captcha.com/2captcha-api#pingback).
