### Installation

#### Automatically

##### With expo-cli

> ✅ The [Expo client app](https://expo.io/tools) comes with the native code installed!

Install the JavaScript with:

  ```bash
  expo install react-native-svg
  ```

📚 See the [**Expo docs**](https://docs.expo.io/versions/latest/sdk/svg/) for more info or jump ahead to [Usage](#Usage).

##### With react-native-cli

1. Install library from `npm`

   ```bash
   yarn add react-native-svg
   ```

2. Link native code

   With autolinking (react-native 0.60+)

   ```bash
   cd ios && pod install
   ```

   Pre 0.60

   ```bash
   react-native link react-native-svg
   ```

# NOTICE:

Due to breaking changes in react-native, the version given in the left column
(and higher versions) of react-native-svg only supports the react-native version
in the right column (and higher versions, if possible).

It is recommended to use the version of react given in the peer dependencies
of the react-native version you are using.

The latest version of react-native-svg should always work in a clean react-native project.

| react-native-svg | react-native |
| ---------------- | ------------ |
| 3.2.0            | 0.29         |
| 4.2.0            | 0.32         |
| 4.3.0            | 0.33         |
| 4.4.0            | 0.38         |
| 4.5.0            | 0.40         |
| 5.1.8            | 0.44         |
| 5.2.0            | 0.45         |
| 5.3.0            | 0.46         |
| 5.4.1            | 0.47         |
| 5.5.1            | >=0.50       |
| >=6              | >=0.50       |
| >=7              | >=0.57.4     |
| >=8              | >=0.57.4     |
| >=9              | >=0.57.4     |

Or, include [this PR](https://github.com/facebook/react-native/pull/17842) manually for v7+ stability on android for older RN ( [included in 0.57-stable](https://github.com/facebook/react-native/commit/d9f5319cf0d9828b29d0e350284b22ce29985042) and newer).

The latest version of v6, v7, v8 and v9 should all work in the latest react-native version.

v7 and newer requires the patch for making android thread safe, to get native animation support.

#### Manually

##### Android pre RN 0.60

1. `yarn add react-native-svg` In RN 0.60+, this is all you should ever need to do get Android working. Before this, react-native link was responsible for the following steps:

2. Append the following lines to `android/settings.gradle`:

   ```gradle
   include ':react-native-svg'
   project(':react-native-svg').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-svg/android')
   ```

3. Insert the following lines inside the dependencies block in `android/app/build.gradle`:

   ```gradle
   implementation project(':react-native-svg')
   ```

4. Open up `android/app/src/main/java/[...]/MainApplication.java`

- Add `import com.horcrux.svg.SvgPackage;` to the imports at the top of the file
- Add `new SvgPackage()` to the list returned by the `getPackages()` method. Add a comma to the previous item if there's already something there.

##### iOS pre RN 0.60

[Manual linking](http://facebook.github.io/react-native/docs/linking-libraries-ios.html#manual-linking)

To install react-native-svg on iOS visit the link referenced above or do the following (react-native link should do this for you):

1. Open your project in XCode and drag the `RNSVG.xcodeproj` file (located in `.../node_modules/react-native-svg/ios`) into the Libraries directory shown in XCode.
2. Expand the `RNSVG.xcodeproj` file you just added to XCode until you see: `libRNSVG.a` (located in `RNSVG.xcodeproj` > `Products` )
3. Drag `libRNSVG.a` into the Link Binary With Libraries section (located in Build Phases which may be found at the top of the XCode window)

###### CocoaPods

Alternatively, you can use [CocoaPods](https://cocoapods.org/) to manage your native (Objective-C and Swift) dependencies:

1. Add RNSVG to your Podfile (with RN 0.60+ autolinking, this is not needed)

```ruby
pod 'RNSVG', :path => '../node_modules/react-native-svg'
```

If `cocoapods` is used and if error `RNSVGImage.m:12:9: 'React/RCTImageLoader.h' file not found` occurs:

Add the following entry in Podfile:

```ruby
    pod 'React', :path => '../node_modules/react-native', :subspecs => [
        [...]
        'RCTImage', # <-- Add RCTImage
    ]
```

and run `pod install` from `ios` folder

### Troubleshooting

#### Problems with Proguard

When Proguard is enabled (which it is by default for Android release builds), it causes runtine error
To avoid this, add an exception to `android/app/proguard-rules.pro`:

```bash
-keep public class com.horcrux.svg.** {*;}
```

If you have build errors, then it might be caused by caching issues, please try:

```bash
watchman watch-del-all
rm -fr $TMPDIR/react-*
react-native start --reset-cache

Or,

rm -rf node_modules
yarn
react-native start --reset-cache
```

#### Unexpected behavior

If you have unexpected behavior, please create a clean project with the latest versions of react-native and react-native-svg

```bash
react-native init CleanProject
cd CleanProject/
yarn add react-native-svg
cd ios && pod install && cd ..
```

Make a reproduction of the problem in `App.js`

```bash
react-native run-ios
react-native run-android
```

# Opening issues

Verify that it is still an issue with the latest version as specified in the previous step. If so, open a new issue, include the entire `App.js` file, specify what platforms you've tested, and the results of running this command:

```bash
react-native info
```

If you suspect that you've found a spec conformance bug, then you can test using your component in a react-native-web project by forking this codesandbox, to see how different browsers render the same content: <https://codesandbox.io/s/pypn6mn3y7> If any evergreen browser with significant userbase or other svg user agent renders some svg content better, or supports more of the svg and related specs, please open an issue asap.

### Usage

Here's a simple example. To render output like this:

![SVG example](https://raw.githubusercontent.com/react-native-community/react-native-svg/master/screenshots/svg.png)

Use the following code:

```jsx
import Svg, {
  Circle,
  Ellipse,
  G,
  Text,
  TSpan,
  TextPath,
  Path,
  Polygon,
  Polyline,
  Line,
  Rect,
  Use,
  Image,
  Symbol,
  Defs,
  LinearGradient,
  RadialGradient,
  Stop,
  ClipPath,
  Pattern,
  Mask,
} from 'react-native-svg';

/* Use this if you are using Expo
import * as Svg from 'react-native-svg';
const { Circle, Rect } = Svg;
*/

import React from 'react';
import { View, StyleSheet } from 'react-native';

export default class SvgExample extends React.Component {
  render() {
    return (
      <View
        style={[
          StyleSheet.absoluteFill,
          { alignItems: 'center', justifyContent: 'center' },
        ]}
      >
        <Svg height="50%" width="50%" viewBox="0 0 100 100">
          <Circle
            cx="50"
            cy="50"
            r="45"
            stroke="blue"
            strokeWidth="2.5"
            fill="green"
          />
          <Rect
            x="15"
            y="15"
            width="70"
            height="70"
            stroke="red"
            strokeWidth="2"
            fill="yellow"
          />
        </Svg>
      </View>
    );
  }
}
```

### Use with content loaded from uri

```jsx
import * as React from 'react';
import { SvgUri } from 'react-native-svg';

export default () => (
  <SvgUri
    width="100%"
    height="100%"
    uri="http://thenewcode.com/assets/images/thumbnails/homer-simpson.svg"
  />
);
```

#### CSS Support

If remote SVG file contains CSS in `<style>` element, use `SvgCssUri`:

```jsx
import * as React from 'react';
import { SvgCssUri } from 'react-native-svg';

export default () => (
  <SvgCssUri
    width="100%"
    height="100%"
    uri="http://thenewcode.com/assets/svg/accessibility.svg"
  />
);
```

### Use with svg files

Try [react-native-svg-transformer](https://github.com/kristerkari/react-native-svg-transformer) to get compile time conversion and cached transformations.
<https://github.com/kristerkari/react-native-svg-transformer#installation-and-configuration>
<https://github.com/kristerkari/react-native-svg-transformer#for-react-native-v057-or-newer--expo-sdk-v3100-or-newer>

`metro.config.js`

```js
const { getDefaultConfig } = require('metro-config');

module.exports = (async () => {
  const {
    resolver: { sourceExts, assetExts },
  } = await getDefaultConfig();
  return {
    transformer: {
      babelTransformerPath: require.resolve('react-native-svg-transformer'),
    },
    resolver: {
      assetExts: assetExts.filter(ext => ext !== 'svg'),
      sourceExts: [...sourceExts, 'svg'],
    },
  };
})();
```

Import your .svg file inside a React component:

```jsx
import Logo from './logo.svg';
```

You can then use your image as a component:

```jsx
<Logo width={120} height={40} />
```

Alternatively, you can use SvgXml with [babel-plugin-inline-import](https://github.com/credcollective/babel-plugin-inline-import/), but with transforms done at run-time.

.babelrc

```json
{
  "presets": ["module:metro-react-native-babel-preset"],
  "plugins": [
    [
      "babel-plugin-inline-import",
      {
        "extensions": [".svg"]
      }
    ]
  ]
}
```

App.js

```jsx
import * as React from 'react';
import { SvgXml } from 'react-native-svg';
import testSvg from './test.svg';
export default () => <SvgXml width="200" height="200" xml={testSvg} />;
```

### Use with xml strings

```jsx
import * as React from 'react';
import { SvgXml } from 'react-native-svg';

const xml = `
  <svg width="32" height="32" viewBox="0 0 32 32">
    <path
      fill-rule="evenodd"
      clip-rule="evenodd"

`;

export default () => <SvgXml xml={xml} width="100%" height="100%" />;
```

#### CSS support

If xml string contains CSS in `<style>` element, use `SvgCss`:

```jsx
import * as React from 'react';
import { SvgCss } from 'react-native-svg';

const xml = `
  <svg width="32" height="32" viewBox="0 0 32 32">
    <style>
      .red {
        fill: #ff0000;
      }
    </style>
    <rect class="red" x="0" y="0" width="32" height="32" />
  </svg>
`;

export default () => <SvgCss xml={xml} width="100%" height="100%" />;
```

### Supported elements:

#### Svg

```jsx
<Svg height="100" width="100">
  <Rect x="0" y="0" width="100" height="100" fill="black" />
  <Circle cx="50" cy="50" r="30" fill="yellow" />
  <Circle cx="40" cy="40" r="4" fill="black" />
  <Circle cx="60" cy="40" r="4" fill="black" />
  <Path d="M 40 60 A 10 10 0 0 0 60 60" stroke="black" />
</Svg>
```

Colors set in the Svg element are inherited by its children:

</Svg>
```

![Pencil](https://raw.githubusercontent.com/react-native-community/react-native-svg/master/screenshots/pencil.png)

Code explanation:

- The fill prop defines the color inside the object.
- The stroke prop defines the color of the line drawn around the object.
- The color prop is a bit special in the sense that it won't color anything by itself, but define a kind of color variable that can be used by children elements. In this example we're defining a "green" color in the Svg element and using it in the second Path element via stroke="currentColor". The "currentColor" is what refers to that "green" value, and it can be used in other props that accept colors too, e.g. fill="currentColor".

#### Rect

The <Rect> element is used to create a rectangle and variations of a rectangle shape:

```jsx
<Svg width="200" height="60">
  <Rect
    x="25"
    y="5"
    width="150"
    height="50"
    fill="rgb(0,0,255)"
    strokeWidth="3"
    stroke="rgb(0,0,0)"
  />
</Svg>
```

![Rect](https://raw.githubusercontent.com/react-native-community/react-native-svg/master/screenshots/rect.png)

Code explanation:

- The width and height props of the <Rect> element define the height and the width of the rectangle.
- The x prop defines the left position of the rectangle (e.g. x="25" places the rectangle 25 px from the left margin).
- The y prop defines the top position of the rectangle (e.g. y="5" places the rectangle 5 px from the top margin).

#### Circle

The <Circle> element is used to create a circle:

```jsx
<Svg height="100" width="100">
  <Circle cx="50" cy="50" r="50" fill="pink" />
</Svg>
```

![Rect](https://raw.githubusercontent.com/react-native-community/react-native-svg/master/screenshots/circle.png)

Code explanation:

- The cx and cy props define the x and y coordinates of the center of the circle. If cx and cy are omitted, the circle's center is set to (0,0)
- The r prop defines the radius of the circle

#### Ellipse

The <Ellipse> element is used to create an ellipse.

An ellipse is closely related to a circle. The difference is that an ellipse has an x and a y radius that differs from each other, while a circle has equal x and y radius.

```jsx
<Svg height="100" width="110">
  <Ellipse
    cx="55"
    cy="55"
    rx="50"
    ry="30"
    stroke="purple"
    strokeWidth="2"
    fill="yellow"
  />
</Svg>
```

![Rect](https://raw.githubusercontent.com/react-native-community/react-native-svg/master/screenshots/ellipse.png)

Code explanation:

- The cx prop defines the x coordinate of the center of the ellipse
- The cy prop defines the y coordinate of the center of the ellipse
- The rx prop defines the horizontal radius
- The ry prop defines the vertical radius

#### Line

The <Line> element is an SVG basic shape, used to create a line connecting two points.

```jsx
<Svg height="100" width="100">
  <Line x1="0" y1="0" x2="100" y2="100" stroke="red" strokeWidth="2" />
</Svg>
```

![Rect](https://raw.githubusercontent.com/react-native-community/react-native-svg/master/screenshots/line.png)

Code explanation:

- The x1 prop defines the start of the line on the x-axis.
- The y1 prop defines the start of the line on the y-axis.
- The x2 prop defines the end of the line on the x-axis.
- The y2 prop defines the end of the line on the y-axis.

#### Polygon

The <Polygon> element is used to create a graphic that contains at least three sides. Polygons are made of straight lines, and the shape is "closed" (all the lines connect up).

```jsx
<Svg height="100" width="100">
  <Polygon
    points="40,5 70,80 25,95"
    fill="lime"
    stroke="purple"
    strokeWidth="1"
  />
</Svg>
```

![Rect](https://raw.githubusercontent.com/react-native-community/react-native-svg/master/screenshots/polygon.png)

Code explanation:

- The points prop defines the x and y coordinates for each corner of the polygon

#### Polyline

The <Polyline> element is used to create any shape that consists of only straight lines:

```jsx
<Svg height="100" width="100">
  <Polyline
    points="10,10 20,12 30,20 40,60 60,70 95,90"
    fill="none"
    stroke="black"
    strokeWidth="3"
  />
</Svg>
```

![Rect](https://raw.githubusercontent.com/react-native-community/react-native-svg/master/screenshots/polyline.png)

Code explanation:

- The points prop defines the x and y coordinates for each point of the polyline

#### Path

The <Path> element is used to define a path.

The following commands are available for path data:

- M = moveto
- L = lineto
- H = horizontal lineto
- V = vertical lineto
- C = curveto
- S = smooth curveto
- Q = quadratic Bézier curve
- T = smooth quadratic Bézier curveto
- A = elliptical Arc
- Z = closepath

`Note:` All of the commands above can also be expressed with lower letters. Capital letters means absolutely positioned, lower cases means relatively positioned. See [Path document of SVG](https://www.w3.org/TR/SVG/paths.html) to know parameters for each command.

```jsx
<Svg height="100" width="100">
  <Path
    d="M25 10 L98 65 L70 25 L16 77 L11 30 L0 4 L90 50 L50 10 L11 22 L77 95 L20 25"
    fill="none"
    stroke="red"
  />
</Svg>
```

![Rect](https://raw.githubusercontent.com/react-native-community/react-native-svg/master/screenshots/path.png)

#### Text

The <Text> element is used to define text.

```jsx
<Svg height="60" width="200">
  <Text
    fill="none"
    stroke="purple"
    fontSize="20"
    fontWeight="bold"
    x="100"
    y="20"
    textAnchor="middle"
  >
    STROKED TEXT
  </Text>
</Svg>
```

![Text](https://raw.githubusercontent.com/react-native-community/react-native-svg/master/screenshots/text.png)

#### TSpan

The <TSpan> element is used to draw multiple lines of text in SVG. Rather than having to position each line of text absolutely, the <TSpan> element makes it possible to position a line of text relatively to the previous line of text.

```jsx
<Svg height="160" width="200">
  <Text y="20" dx="5 5">
    <TSpan x="10">tspan line 1</TSpan>
    <TSpan x="10" dy="15">
      tspan line 2
    </TSpan>
    <TSpan x="10" dx="10" dy="15">
      tspan line 3
    </TSpan>
  </Text>
  <Text x="10" y="60" fill="red" fontSize="14">
    <TSpan dy="5 10 20">12345</TSpan>
    <TSpan fill="blue" dy="15" dx="0 5 5">
      <TSpan>6</TSpan>
      <TSpan>7</TSpan>
    </TSpan>
    <TSpan dx="0 10 20" dy="0 20" fontWeight="bold" fontSize="12">
      89a
    </TSpan>
  </Text>
  <Text y="140" dx="0 5 5" dy="0 -5 -5">
    delta on text
  </Text>
</Svg>
```

![TSpan](https://raw.githubusercontent.com/react-native-community/react-native-svg/master/screenshots/tspan.png)

#### TextPath

In addition to text drawn in a straight line, SVG also includes the ability to place text along the shape of a <Path> element. To specify that a block of text is to be rendered along the shape of a <Path>, include the given text within a <TextPath> element which includes an href attribute with a reference to a <Path> element.

```jsx
<Svg height="100" width="200">
  <Defs>
    <Path id="path" d={path} />
  </Defs>
  <G y="20">
    <Text fill="blue">
      <TextPath href="#path" startOffset="-10%">
        We go up and down,
        <TSpan fill="red" dy="5,5,5">
          then up again
        </TSpan>
      </TextPath>
    </Text>
    <Path d={path} fill="none" stroke="red" strokeWidth="1" />
  </G>
</Svg>
```

![TextPath](https://raw.githubusercontent.com/react-native-community/react-native-svg/master/screenshots/text-path.png)

#### G

The <G> element is a container used to group other SVG elements. Transformations applied to the g element are performed on all of its child elements, and any of its props are inherited by its child elements. It can also group multiple elements to be referenced later with the [&lt;Use /&gt;](#use) element.

```jsx
<Svg height="100" width="200">
  <G rotation="50" origin="100, 50">
    <Line x1="60" y1="10" x2="140" y2="10" stroke="#060" />

    <Rect x="60" y="20" height="50" width="80" stroke="#060" fill="#060" />

    <Text x="100" y="75" stroke="#600" fill="#600" textAnchor="middle">
      Text grouped with shapes
    </Text>
  </G>
</Svg>
```

![G](https://raw.githubusercontent.com/react-native-community/react-native-svg/master/screenshots/g.png)

#### Use

The <Use> element can reuse an SVG shape from elsewhere in the SVG document, including <G> elements and <Symbol> elements. The reused shape can be defined inside the [&lt;Defs&gt;](#defs) element (which makes the shape invisible until used) or outside.

```jsx
<Svg height="100" width="300">
  <Defs>
    <G id="shape">
      <G>
        <Circle cx="50" cy="50" r="50" />
        <Rect x="50" y="50" width="50" height="50" />
        <Circle cx="50" cy="50" r="5" fill="blue" />
      </G>
    </G>
  </Defs>
  <Use href="#shape" x="20" y="0" />
  <Use href="#shape" x="170" y="0" />
</Svg>
```

This example shows a <G> element defined inside a [&lt;Defs&gt;](#defs) element. This makes the <G> invisible unless referenced by a <Use> element.

Before the <G> element can be referenced, it must have an ID set on it via its id prop. The <Use> element references the <G> element via its `href` prop. Notice the # in front of the ID in the prop value.

The <Use> element specifies where to show the reused shapes via its x and y props. Notice that the shapes inside the <G> element are located at 0,0. That is done because their position is added to the position specified in the <Use> element.

![use](https://raw.githubusercontent.com/react-native-community/react-native-svg/master/screenshots/use.png)

#### Symbol

The SVG <Symbol> element is used to define reusable symbols. The shapes nested inside a <Symbol> are not displayed unless referenced by a <Use> element.

```jsx
<Svg height="150" width="110">
  <Symbol id="symbol" viewBox="0 0 150 110" width="100" height="50">
    <Circle cx="50" cy="50" r="40" strokeWidth="8" stroke="red" fill="red" />
    <Circle
      cx="90"
      cy="60"
      r="40"
      strokeWidth="8"
      stroke="green"
      fill="white"
    />
  </Symbol>

  <Use href="#symbol" x="0" y="0" />
  <Use href="#symbol" x="0" y="50" width="75" height="38" />
  <Use href="#symbol" x="0" y="100" width="50" height="25" />
</Svg>
```

![Symbol](https://raw.githubusercontent.com/react-native-community/react-native-svg/master/screenshots/symbol.png)

#### Defs

The <Defs> element is used to embed definitions that can be reused inside an SVG image. For instance, you can group SVG shapes together and reuse them as a single shape.

#### Image

The <Image> element allows a raster image to be included in an Svg component.

```jsx
<Svg height="100" width="100">
  <Defs>
    <ClipPath id="clip">
      <Circle cx="50%" cy="50%" r="40%" />
    </ClipPath>
  </Defs>
  <Rect x="0" y="0" width="100%" height="100%" fill="red" />
  <Rect x="5%" y="5%" width="50%" height="90%" />

  <Image
    x="5%"
    y="5%"
    width="50%"
    height="90%"
    preserveAspectRatio="xMidYMid slice"
    opacity="0.5"
    href={require('../image.jpg')}
    clipPath="url(#clip)"
  />
  <Text
    x="50"
    y="50"
    textAnchor="middle"
    fontWeight="bold"
    fontSize="16"
    fill="blue"
  >
    HOGWARTS
  </Text>
</Svg>
```

![Image](https://raw.githubusercontent.com/react-native-community/react-native-svg/master/screenshots/image.png)

#### ClipPath

The <ClipPath> SVG element defines a clipping path. A clipping path is used/referenced using the clipPath property

```jsx
<Svg height="100" width="100">
  <Defs>
    <RadialGradient
      id="grad"
      cx="50%"
      cy="50%"
      rx="50%"
      ry="50%"
      fx="50%"
      fy="50%"
      gradientUnits="userSpaceOnUse"
    >
      <Stop offset="0%" stopColor="#ff0" stopOpacity="1" />
      <Stop offset="100%" stopColor="#00f" stopOpacity="1" />
    </RadialGradient>
    <ClipPath id="clip">
      <G scale="0.9" x="10">
        <Circle cx="30" cy="30" r="20" />
        <Ellipse cx="60" cy="70" rx="20" ry="10" />
        <Rect x="65" y="15" width="30" height="30" />
        <Polygon points="20,60 20,80 50,70" />
        <Text
          x="50"
          y="30"
          fontSize="32"
          fonWeight="bold"
          textAnchor="middle"
          scale="1.2"
        >
          Q
        </Text>
      </G>
    </ClipPath>
  </Defs>
  <Rect
    x="0"
    y="0"
    width="100"
    height="100"
    fill="url(#grad)"
    clipPath="url(#clip)"
  />
</Svg>
```

![ClipPath](https://raw.githubusercontent.com/react-native-community/react-native-svg/master/screenshots/clip-path.png)

#### LinearGradient

The <LinearGradient> element is used to define a linear gradient.
The <LinearGradient> element must be nested within a [&lt;Defs&gt;](#defs) tag. The [&lt;Defs&gt;](#defs) tag is short for definitions and contains definition of special elements (such as gradients).

Linear gradients can be defined as horizontal, vertical or angular gradients:

- Horizontal gradients are created when y1 and y2 are equal and x1 and x2 differ
- Vertical gradients are created when x1 and x2 are equal and y1 and y2 differ
- Angular gradients are created when x1 and x2 differ and y1 and y2 differ

```jsx
<Svg height="150" width="300">
  <Defs>
    <LinearGradient id="grad" x1="0" y1="0" x2="1" y2="0">
      <Stop offset="0" stopColor="#FFD080" stopOpacity="1" />
      <Stop offset="1" stopColor="red" stopOpacity="1" />
    </LinearGradient>
  </Defs>
  <Ellipse cx="150" cy="75" rx="85" ry="55" fill="url(#grad)" />
</Svg>
```

Code explanation:

- The id prop of the <LinearGradient> tag defines a unique name for the gradient
- The x1, x2, y1,y2 props of the <LinearGradient> tag define the start and end position of the gradient
- The color range for a gradient can be composed of two or more colors. Each color is specified with a <Stop> tag. The offset prop is used to define where the gradient color begin and end
- The fill prop links the ellipse element to the gradient

![LinearGradient](https://raw.githubusercontent.com/react-native-community/react-native-svg/master/screenshots/lineargradient.png)

_NOTICE:_
LinearGradient also supports percentage as prop:

```jsx
<LinearGradient id="grad" x1="0%" y1="0%" x2="100%" y2="0%">
  <Stop offset="0%" stopColor="rgb(255,255,0)" stopOpacity="0" />
  <Stop offset="100%" stopColor="red" stopOpacity="1" />
</LinearGradient>
```

This result is same as the example before. But it's recommend to use exact number instead; it has performance advantages over using percentages.

#### RadialGradient

The <RadialGradient> element is used to define a radial gradient. The <RadialGradient> element must be nested within a [&lt;Defs&gt;](#defs) tag. The [&lt;Defs&gt;](#defs) tag is short for definitions and contains definition of special elements (such as gradients).

```jsx
<Svg height="150" width="300">
  <Defs>
    <RadialGradient
      id="grad"
      cx="150"
      cy="75"
      rx="85"
      ry="55"
      fx="150"
      fy="75"
      gradientUnits="userSpaceOnUse"
    >
      <Stop offset="0" stopColor="#ff0" stopOpacity="1" />
      <Stop offset="1" stopColor="#83a" stopOpacity="1" />
    </RadialGradient>
  </Defs>
  <Ellipse cx="150" cy="75" rx="85" ry="55" fill="url(#grad)" />
</Svg>
```

Code explanation:

- The id prop of the <radialGradient> tag defines a unique name for the gradient
- The cx, cy and r props define the outermost circle and the fx and fy define the innermost circle
- The color range for a gradient can be composed of two or more colors. Each color is specified with a <stop> tag. The offset prop is used to define where the gradient color begin and end
- The fill prop links the ellipse element to the gradient

![RadialGradient](https://raw.githubusercontent.com/react-native-community/react-native-svg/master/screenshots/radialgradient.png)

#### Mask

In SVG, you can specify that any other graphics object or ‘G’ element can be used as an alpha mask for compositing the current object into the background.

A mask is defined with a ‘Mask’ element. A mask is used/referenced using the ‘mask’ property.

A ‘Mask’ can contain any graphical elements or container elements such as a ‘G’.

The <Mask> element must be nested within a [&lt;Defs&gt;](#defs) tag. The [&lt;Defs&gt;](#defs) tag is short for definitions and contains definition of special elements (such as gradients).

<https://www.w3.org/TR/SVG11/images/masking/mask01.svg>

```jsx
<Svg width="100%" height="100%" viewBox="0 0 800 300">
  <Defs>
    <LinearGradient
      id="Gradient"
      gradientUnits="userSpaceOnUse"
      x1="0"
      y1="0"
      x2="800"
      y2="0"
    >
      <Stop offset="0" stopColor="white" stopOpacity="0" />
      <Stop offset="1" stopColor="white" stopOpacity="1" />
    </LinearGradient>
    <Mask
      id="Mask"
      maskUnits="userSpaceOnUse"
      x="0"
      y="0"
      width="800"
      height="300"
    >
      <Rect x="0" y="0" width="800" height="300" fill="url(#Gradient)" />
    </Mask>
    <Text
      id="Text"
      x="400"
      y="200"
      fontFamily="Verdana"
      fontSize="100"
      textAnchor="middle"
    >
      Masked text
    </Text>
  </Defs>
  <Rect x="0" y="0" width="800" height="300" fill="#FF8080" />
  <Use href="#Text" fill="blue" mask="url(#Mask)" />
  <Use href="#Text" fill="none" stroke="black" stroke-width="2" />
</Svg>
```

Code explanation: <https://www.w3.org/TR/SVG11/masking.html#MaskElement>

![Mask](https://www.w3.org/TR/SVG11/images/masking/mask01.svg)

v10 adds experimental support for using masks together with native elements.
If you had native elements inside any Svg root before (which was unsupported),
Then your content might change appearance when upgrading,
as e.g. transforms and masks now take effect.

#### Pattern

A pattern is used to fill or stroke an object using a pre-defined graphic object which can be replicated ("tiled") at fixed intervals in x and y to cover the areas to be painted. Patterns are defined using a ‘pattern’ element and then referenced by properties ‘fill’ and ‘stroke’ on a given graphics element to indicate that the given element shall be filled or stroked with the referenced pattern.
The <Pattern> element must be nested within a [&lt;Defs&gt;](#defs) tag. The [&lt;Defs&gt;](#defs) tag is short for definitions and contains definition of special elements (such as gradients).

<https://www.w3.org/TR/SVG11/images/pservers/pattern01.svg>

```jsx
<Svg width="100%" height="100%" viewBox="0 0 800 400">
  <Defs>
    <Pattern
      id="TrianglePattern"
      patternUnits="userSpaceOnUse"
      x="0"
      y="0"
      width="100"
      height="100"
      viewBox="0 0 10 10"
    >
      <Path d="M 0 0 L 7 0 L 3.5 7 z" fill="red" stroke="blue" />
    </Pattern>
  </Defs>
  <Rect fill="none" stroke="blue" x="1" y="1" width="798" height="398" />
  <Ellipse
    fill="url(#TrianglePattern)"
    stroke="black"
    strokeWidth="5"
    cx="400"
    cy="200"
    rx="350"
    ry="150"
  />
</Svg>
```

#### Marker

A marker is a symbol which is attached to one or more vertices of ‘path’, ‘line’, ‘polyline’ and ‘polygon’ elements. Typically, markers are used to make arrowheads or polymarkers. Arrowheads can be defined by attaching a marker to the start or end vertices of ‘path’, ‘line’ or ‘polyline’ elements. Polymarkers can be defined by attaching a marker to all vertices of a ‘path’, ‘line’, ‘polyline’ or ‘polygon’ element.

The graphics for a marker are defined by a ‘marker’ element. To indicate that a particular ‘marker’ element should be rendered at the vertices of a particular ‘path’, ‘line’, ‘polyline’ or ‘polygon’ element, set one or more marker properties (‘marker’, ‘marker-start’, ‘marker-mid’ or ‘marker-end’) to reference the given ‘marker’ element.

<https://www.w3.org/TR/SVG11/images/painting/marker.svg>

```jsx
<Svg width="400" height="200" viewBox="0 0 4000 2000">
  <Defs>
    <Marker
      id="Triangle"
      viewBox="0 0 10 10"

#### ForeignObject

SVG is designed to be compatible with other XML languages for describing and rendering other types of content. The ‘foreignObject’ element allows for inclusion of elements in a non-SVG namespace which is rendered within a region of the SVG graphic using other user agent processes. The included foreign graphical content is subject to SVG transformations, filters, clipping, masking and compositing.

One goal for SVG is to provide a mechanism by which other XML language processors can render into an area within an SVG drawing, with those renderings subject to the various transformations and compositing parameters that are currently active at a given point within the SVG content tree. One particular example of this is to provide a frame for XML content styled with CSS or XSL so that dynamically reflowing text (subject to SVG transformations and compositing) could be inserted into the middle of some SVG content.

#### Touch Events

Touch events are supported in react-native-svg. These include:

- `disabled`
- `onPress`
- `onPressIn`
- `onPressOut`
- `onLongPress`
- `delayPressIn`
- `delayPressOut`
- `delayLongPress`

You can use these events to provide interactivity to your react-native-svg components.

```jsx
<Circle
  cx="50%"
  cy="50%"
  r="38%"
  fill="red"
  onPress={() => alert('Press on Circle')}
/>
```

For more examples of touch in action, checkout the [TouchEvents.js examples](https://github.com/magicismight/react-native-svg-example/blob/master/examples/TouchEvents.js).

### Serialize

```jsx
import * as React from 'react';
import { Platform, StyleSheet, TouchableOpacity } from 'react-native';
import { Svg, Rect } from 'react-native-svg';
import ReactDOMServer from 'react-dom/server';

const isWeb = Platform.OS === 'web';

const childToWeb = child => {
  const { type, props } = child;
  const name = type && type.displayName;
  const webName = name && name[0].toLowerCase() + name.slice(1);
  const Tag = webName ? webName : type;
  return <Tag {...props}>{toWeb(props.children)}</Tag>;
};

const toWeb = children => React.Children.map(children, childToWeb);

export default class App extends React.Component {
  renderSvg() {
    return (
      <Svg height="100%" width="100%" style={{ backgroundColor: '#33AAFF' }}>
        <Rect
          x="50"
          y="50"
          width="50"
          height="50"
          fill="#3399ff"
          strokeWidth="3"
          stroke="rgb(0,0,0)"
        />
      </Svg>
    );
  }
  serialize = () => {
    const element = this.renderSvg();
    const webJsx = isWeb ? element : toWeb(element);
    const svgString = ReactDOMServer.renderToStaticMarkup(webJsx);
    console.log(svgString);
  };
  render() {
    return (
      <TouchableOpacity style={styles.container} onPress={this.serialize}>
        {this.renderSvg()}
      </TouchableOpacity>
    );
  }
}

const styles = StyleSheet.create({
  container: {
    flex: 1,
    justifyContent: 'center',
    backgroundColor: '#ecf0f1',
    padding: 8,
  },
});
```
