-
-[](https://github.com/Brooooooklyn/canvas/actions/workflows/CI.yaml)
-
-[](https://packagephobia.com/result?p=@napi-rs/canvas)
-[](https://npmcharts.com/compare/@napi-rs/canvas?minimal=true)
-
-> 🚀 Help me to become a full-time open-source developer by [sponsoring me on Github](https://github.com/sponsors/Brooooooklyn)
-
-Google Skia binding to Node.js via [Node-API](https://napi.rs), **0 System dependencies!**
-
-⚠️ This project is in pre-release stage. And there may be some bugs.
-For details on planned features and future direction please refer to the [Roadmap](https://github.com/Brooooooklyn/canvas/issues/113).
-
-[中文文档](./README-zh.md)
-
-# Install
-
-```bash
-yarn add @napi-rs/canvas
-npm install @napi-rs/canvas
-```
-
-# Support matrix
-
-## System requirement
-
-### `arm64`
-
-[**_cortex-a57_**](https://en.wikipedia.org/wiki/ARM_Cortex-A57) or newer CPU architecture on **Linux**.
-
-All Apple M chips on **macOS**.
-
-### `armv7`
-
-[**_cortex-a7_**](https://en.wikipedia.org/wiki/ARM_Cortex-A7) or newer CPU architecture.
-
-### glibc
-
-Since Skia relies on the [glibc](https://www.gnu.org/software/libc/) 2.18 API, you need to have at least glibc version >= 2.18 on your system.
-
-## AWS Lambda usage
-
-To use this library on Lambda you will need to use a Lambda layer.
-
-You can simply attach a lambda layer by getting an ARN from [Canvas-Lambda-Layer](https://github.com/ShivamJoker/Canvas-Lambda-Layer)
-
-> Make sure to exclude `@napi-rs/canvas` while bundling your Lambda.
-
-# Usage
-
-```js
-const { promises } = require('node:fs')
-const { join } = require('node:path')
-const { createCanvas, loadImage } = require('@napi-rs/canvas')
-
-const canvas = createCanvas(300, 320)
-const ctx = canvas.getContext('2d')
-
-ctx.lineWidth = 10
-ctx.strokeStyle = '#03a9f4'
-ctx.fillStyle = '#03a9f4'
-
-// Wall
-ctx.strokeRect(75, 140, 150, 110)
-
-// Door
-ctx.fillRect(130, 190, 40, 60)
-
-// Roof
-ctx.beginPath()
-ctx.moveTo(50, 140)
-ctx.lineTo(150, 60)
-ctx.lineTo(250, 140)
-ctx.closePath()
-ctx.stroke()
-
-async function main() {
- // load images from disk or from a URL
- const catImage = await loadImage('path/to/cat.png')
- const dogImage = await loadImage('https://example.com/path/to/dog.jpg')
-
- ctx.drawImage(catImage, 0, 0, catImage.width, catImage.height)
-
- ctx.drawImage(dogImage, canvas.width / 2, canvas.height / 2, dogImage.width, dogImage.height)
-
- // export canvas as image
- const pngData = await canvas.encode('png') // JPEG, AVIF and WebP are also supported
- // encoding in libuv thread pool, non-blocking
- await promises.writeFile(join(__dirname, 'simple.png'), pngData)
-}
-
-main()
-```
-
-
-
-## Emoji text
-
-```js
-const { writeFileSync } = require('fs')
-const { join } = require('path')
-
-const { createCanvas, GlobalFonts } = require('@napi-rs/canvas')
-
-GlobalFonts.registerFromPath(join(__dirname, '..', 'fonts', 'AppleColorEmoji@2x.ttf'), 'Apple Emoji')
-GlobalFonts.registerFromPath(join(__dirname, '..', '__test__', 'fonts', 'COLRv1.ttf'), 'COLRv1')
-
-console.info(GlobalFonts.families)
-
-const canvas = createCanvas(760, 360)
-const ctx = canvas.getContext('2d')
-
-ctx.font = '50px Apple Emoji'
-ctx.strokeText('😀😃😄😁😆😅😂🤣☺️😊😊😇', 50, 150)
-
-ctx.font = '100px COLRv1'
-ctx.fillText('abc', 50, 300)
-
-const b = canvas.toBuffer('image/png')
-
-writeFileSync(join(__dirname, 'draw-emoji.png'), b)

-## PathKit
-
-`PathKit` is a toolset for manipulating Path in `Skia`, supporting **_quadratic beziers_**, **_cubic beziers_** and **_conics_**.
-The main features are.
-
-### Path Operation
-
-`.op(path, PathOp)`
-
-```js
-const pathOne = new Path2D(
- 'M8 50H92C96.4183 50 100 53.5817 100 58V142C100 146.418 96.4183 150 92 150H8C3.58172 150 0 146.418 0 142V58C0 53.5817 3.58172 50 8 50Z',
-)
-const pathTwo = new Path2D(
- '"M58 0H142C146.418 0 150 3.58172 150 8V92C150 96.4183 146.418 100 142 100H58C53.5817 100 50 96.4183 50 92V8C50 3.58172 53.5817 0 58 0Z',
-)
-
-pathOne.op(pathTwo, PathOp.Intersect).toSVGString()
-// => "M100 100L58 100C53.5817 100 50 96.4183 50 92L50 50L92 50C96.4183 50 100 53.5817 100 58L100 100Z"
-```
-
-- **Union**, subtract the op path from the first path
-- **Difference**, intersect the two paths
-- **ReverseDifference**, union (inclusive-or) the two paths
-- **Intersect**, exclusive-or the two paths
-- **XOR**, subtract the first path from the op path
-
-
-
-### Covert `FillType` in **_Path_**
-
-`.asWinding()`
-
-You can convert `fill-rule="evenodd"` to `fill-rule="nonzero"` in SVG.
-This is useful for **OpenType** font-related tools, as `fill-rule="nonzero"` is only supported in **OpenType** fonts.
-

-You can build this project from source, the system requirements are here: https://skia.org/docs/user/build
-
-```sh
-# Clone the code:
-$ git clone --recurse-submodules https://github.com/Brooooooklyn/canvas.git
-$ cd canvas
-
-# Build Skia:
-$ node scripts/build-skia.js
-
-# Install NPM packages, build the Node.js addon:
-$ npm install -g yarn
-$ yarn install --mode=skip-build # Here are modules that are used for benchmarking and are hard to install, you can skip it by specifying `--mode=skip-build`
-$ sudo dnf install clang # https://fedora.pkgs.org/34/fedora-x86_64/clang-12.0.0-0.3.rc1.fc34.x86_64.rpm.html

- * but as the **Cb** and **Cr** channels are only sampled on each alternate line in this scheme, the vertical resolution is halved.
- * The data rate is thus the same.
- * This fits reasonably well with the PAL color encoding system, since this has only half the vertical chrominance resolution of [NTSC](https://en.wikipedia.org/wiki/NTSC).
- * It would also fit extremely well with the [SECAM](https://en.wikipedia.org/wiki/SECAM) color encoding system,
- * since like that format, 4:2:0 only stores and transmits one color channel per line (the other channel being recovered from the previous line).
- * However, little equipment has actually been produced that outputs a SECAM analogue video signal.
- * In general, SECAM territories either have to use a PAL-capable display or a [transcoder](https://en.wikipedia.org/wiki/Transcoding) to convert the PAL signal to SECAM for display.

-
-[](https://packagephobia.com/result?p=@napi-rs/canvas)
-[](https://npmcharts.com/compare/@napi-rs/canvas?minimal=true)
-
-> 🚀 Help me to become a full-time open-source developer by [sponsoring me on Github](https://github.com/sponsors/Brooooooklyn)
-
-Google Skia binding to Node.js via [Node-API](https://napi.rs), **0 System dependencies!**
-
-⚠️ This project is in pre-release stage. And there may be some bugs.
-For details on planned features and future direction please refer to the [Roadmap](https://github.com/Brooooooklyn/canvas/issues/113).
-
-[中文文档](./README-zh.md)
-
-# Install
-
-```bash
-yarn add @napi-rs/canvas
-npm install @napi-rs/canvas
-```
-
-# Support matrix
-
-## System requirement
-
-### `arm64`
-
-[**_cortex-a57_**](https://en.wikipedia.org/wiki/ARM_Cortex-A57) or newer CPU architecture on **Linux**.
-
-All Apple M chips on **macOS**.
-
-### `armv7`
-
-[**_cortex-a7_**](https://en.wikipedia.org/wiki/ARM_Cortex-A7) or newer CPU architecture.
-
-### glibc
-
-Since Skia relies on the [glibc](https://www.gnu.org/software/libc/) 2.18 API, you need to have at least glibc version >= 2.18 on your system.
-
-## AWS Lambda usage
-
-To use this library on Lambda you will need to use a Lambda layer.
-
-You can simply attach a lambda layer by getting an ARN from [Canvas-Lambda-Layer](https://github.com/ShivamJoker/Canvas-Lambda-Layer)
-
-> Make sure to exclude `@napi-rs/canvas` while bundling your Lambda.
-
-# Usage
-
-```js
-const { promises } = require('node:fs')
-const { join } = require('node:path')
-const { createCanvas, loadImage } = require('@napi-rs/canvas')
-
-const canvas = createCanvas(300, 320)
-const ctx = canvas.getContext('2d')
-
-ctx.lineWidth = 10
-ctx.strokeStyle = '#03a9f4'
-ctx.fillStyle = '#03a9f4'
-
-// Wall
-ctx.strokeRect(75, 140, 150, 110)
-
-// Door
-ctx.fillRect(130, 190, 40, 60)
-
-// Roof
-ctx.beginPath()
-ctx.moveTo(50, 140)
-ctx.lineTo(150, 60)
-ctx.lineTo(250, 140)
-ctx.closePath()
-ctx.stroke()
-
-async function main() {
- // load images from disk or from a URL
- const catImage = await loadImage('path/to/cat.png')
- const dogImage = await loadImage('https://example.com/path/to/dog.jpg')
-
- ctx.drawImage(catImage, 0, 0, catImage.width, catImage.height)
-
- ctx.drawImage(dogImage, canvas.width / 2, canvas.height / 2, dogImage.width, dogImage.height)
-
- // export canvas as image
- const pngData = await canvas.encode('png') // JPEG, AVIF and WebP are also supported
- // encoding in libuv thread pool, non-blocking
- await promises.writeFile(join(__dirname, 'simple.png'), pngData)
-}
-
-main()
-```
-
-
-
-## Emoji text
-
-```js
-const { writeFileSync } = require('fs')
-const { join } = require('path')
-
-const { createCanvas, GlobalFonts } = require('@napi-rs/canvas')
-
-GlobalFonts.registerFromPath(join(__dirname, '..', 'fonts', 'AppleColorEmoji@2x.ttf'), 'Apple Emoji')
-GlobalFonts.registerFromPath(join(__dirname, '..', '__test__', 'fonts', 'COLRv1.ttf'), 'COLRv1')
-
-console.info(GlobalFonts.families)
-
-const canvas = createCanvas(760, 360)
-const ctx = canvas.getContext('2d')
-
-ctx.font = '50px Apple Emoji'
-ctx.strokeText('😀😃😄😁😆😅😂🤣☺️😊😊😇', 50, 150)
-
-ctx.font = '100px COLRv1'
-ctx.fillText('abc', 50, 300)
-
-const b = canvas.toBuffer('image/png')
-
-writeFileSync(join(__dirname, 'draw-emoji.png'), b)

-## PathKit
-
-`PathKit` is a toolset for manipulating Path in `Skia`, supporting **_quadratic beziers_**, **_cubic beziers_** and **_conics_**.
-The main features are.
-
-### Path Operation
-
-`.op(path, PathOp)`
-
-```js
-const pathOne = new Path2D(
- 'M8 50H92C96.4183 50 100 53.5817 100 58V142C100 146.418 96.4183 150 92 150H8C3.58172 150 0 146.418 0 142V58C0 53.5817 3.58172 50 8 50Z',
-)
-const pathTwo = new Path2D(
- '"M58 0H142C146.418 0 150 3.58172 150 8V92C150 96.4183 146.418 100 142 100H58C53.5817 100 50 96.4183 50 92V8C50 3.58172 53.5817 0 58 0Z',
-)
-
-pathOne.op(pathTwo, PathOp.Intersect).toSVGString()
-// => "M100 100L58 100C53.5817 100 50 96.4183 50 92L50 50L92 50C96.4183 50 100 53.5817 100 58L100 100Z"
-```
-
-- **Union**, subtract the op path from the first path
-- **Difference**, intersect the two paths
-- **ReverseDifference**, union (inclusive-or) the two paths
-- **Intersect**, exclusive-or the two paths
-- **XOR**, subtract the first path from the op path
-
-
-
-### Covert `FillType` in **_Path_**
-
-`.asWinding()`
-
-You can convert `fill-rule="evenodd"` to `fill-rule="nonzero"` in SVG.
-This is useful for **OpenType** font-related tools, as `fill-rule="nonzero"` is only supported in **OpenType** fonts.
-

- * but as the **Cb** and **Cr** channels are only sampled on each alternate line in this scheme, the vertical resolution is halved.
- * The data rate is thus the same.
- * This fits reasonably well with the PAL color encoding system, since this has only half the vertical chrominance resolution of [NTSC](https://en.wikipedia.org/wiki/NTSC).
- * It would also fit extremely well with the [SECAM](https://en.wikipedia.org/wiki/SECAM) color encoding system,
- * since like that format, 4:2:0 only stores and transmits one color channel per line (the other channel being recovered from the previous line).
- * However, little equipment has actually been produced that outputs a SECAM analogue video signal.
- * In general, SECAM territories either have to use a PAL-capable display or a [transcoder](https://en.wikipedia.org/wiki/Transcoding) to convert the PAL signal to SECAM for display.
