# SpineViewer 1.1.1
|
||||
|
||||
Eagle 的离线 Spine 骨骼动画预览插件，支持 Spine 3.4、3.5、3.6、3.7、3.8、4.0、4.1、4.2、4.3。
|
||||
|
||||
本包为**windows和macos通用包**，同时适用于 **Windows x64** 与 **macOS Apple 芯片**。
|
||||
Eagle 的离线 Spine 骨骼动画预览插件，支持 Spine 3.4–4.3，适用于 Windows 和 macOS。
|
||||
|
||||
## 功能与使用
|
||||
|
||||
1. 将同一套骨骼文件（`.skel` / `.skel.bytes` / Spine `.json`）、图集（`.atlas` / `.atlas.txt`）和配套贴图一起导入 Eagle，建议放在同一个 Eagle 文件夹内，并保留文件名配对关系。
|
||||
2. 打开骨骼或图集文件即可预览。普通图片仍使用 Eagle 原生预览。
|
||||
3. 支持动画和皮肤切换、播放/暂停（空格）、循环、速度、时间轴拖动、缩放适配、背景与预乘 Alpha（PMA）切换。
|
||||
4. 自动生成带 Spine 标记和版本号的当前素材缩略图，也可在预览器中主动将当前帧设为当前素材的自定义缩略图。已有自定义缩略图时会先确认；插件不会自动改写同组其他素材。
|
||||
5. 若导入时资源尚未配齐，会先显示回退图；补齐后请使用 Eagle 的“刷新缩略图”重新生成。
|
||||
1. 将同一套骨骼文件（`.skel` / `.skel.bytes` / Spine `.json`）、图集（`.atlas` / `.atlas.txt`）和配套贴图一起导入 Eagle，建议放在同一个 Eagle 文件夹内。
|
||||
2. 打开骨骼或图集文件即可预览动画，并可切换动画、皮肤、速度、循环、背景和 PMA。
|
||||
3. 插件不接管导入阶段的缩略图，由 Eagle 自身处理。
|
||||
4. 打开预览后，可点击“设为当前素材缩略图”，把当前帧手动设为当前素材的自定义缩略图。已有自定义缩略图时会先询问是否替换。
|
||||
|
||||
## 安全与隐私
|
||||
|
||||
- Atlas 贴图只允许安全的相对路径；绝对路径、`..`、盘符、UNC、URI 和越界符号链接会被拒绝。跨素材配对只使用当前 Eagle 素材库中已枚举并验证的素材。
|
||||
- 自动缩略图只写 Eagle 为当前素材提供的目标，不会改写同组其他素材。手动设置也只作用于当前素材；已有自定义缩略图时会先确认。
|
||||
- 诊断日志默认关闭。显式设置 `SPINEVIEWER_DEBUG_LOG=1` 时，日志只写系统临时目录，不写插件目录，也不会进入安装包。
|
||||
|
||||
## 平台与依赖
|
||||
|
||||
`node_modules/@napi-rs/` 下并排携带三个包，运行时由 `@napi-rs/canvas` 依据 `process.platform` 与 `process.arch` 自动选择，未匹配的平台包不会被加载：
|
||||
|
||||
| 平台 | 原生包目录 |
|
||||
| --- | --- |
|
||||
| Windows x64 | `canvas-win32-x64-msvc` |
|
||||
| macOS Apple 芯片 | `canvas-darwin-arm64` |
|
||||
| 公共代码（两平台共用） | `canvas` |
|
||||
|
||||
原生包版本均为 **0.1.66**。
|
||||
|
||||
清单使用 `platform: all` / `arch: all`。本包**未包含 macOS Intel 与 Windows ARM64 的原生二进制**：这两种环境下动画预览仍可正常使用。
|
||||
- Atlas 贴图只允许安全的相对路径；绝对路径、`..`、盘符、UNC、URI 和越界符号链接会被拒绝。
|
||||
- 跨素材配对只使用当前 Eagle 素材库中已枚举并验证的文件。
|
||||
- 手动设置缩略图只作用于当前素材，不会自动改写其他素材。
|
||||
|
||||
## 多语言
|
||||
|
||||
界面支持简体中文、繁体中文、English、日本語、한국어、Русский、Español、Deutsch，随 Eagle 的界面语言切换，无法识别时回退到简体中文。文案位于 `_locales/`。
|
||||
支持简体中文、繁体中文、English、日本語、한국어、Русский、Español 和 Deutsch。

|
||||
|
||||
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.<br/>
|
||||
For details on planned features and future direction please refer to the [Roadmap](https://github.com/Brooooooklyn/canvas/issues/113).

# Install
|
||||
|
||||
```bash
|
||||
yarn add @napi-rs/canvas
|
||||
npm install @napi-rs/canvas
|
||||
```
|
||||

## 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.
|
||||
|
||||

## 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.
|
||||
|
||||
|
||||
|
||||
```js
|
||||
const pathCircle = new Path2D(
|
||||

```
|
||||
|
||||
### Simplify **_Path_**
|
||||
|
||||
`.simplify()`
|
||||
|
||||
Set the path to the same non-overlapping contour as the original path area, which means that it can also remove overlapping paths.

# Building
|
||||
|
||||
## Build skia from source
|
||||
|
||||
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
|
||||
$ yarn build
|
||||
|
||||
# All done! Run test cases or examples now:
|
||||
$ yarn test
|
||||
$ node example/tiger.js
|
||||
```
|
||||
|
||||
## Pull pre-build skia binary from GitHub
|
||||
|
||||
You can pull skia pre-build binaries if you just care the `Rust` part:
|
||||
|
||||
```sh
|
||||
# Clone the code:
|
||||
$ git clone --recurse-submodules https://github.com/Brooooooklyn/canvas.git
|
||||
$ cd canvas
|
||||
|
||||
# Download Skia binaries:
|
||||
# It will pull the binaries match the git hash in `./skia` submodule
|
||||
$ node scripts/release-skia-binary.mjs --download
|
||||
|
||||
# Install NPM packages, build the Node.js addon:
|
||||
$ npm install -g yarn
|
||||
$ yarn install --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
|
||||
$ yarn build
|
||||
|
||||
# All done! Run test cases or examples now:
|
||||
$ yarn test
|
||||
$ node example/tiger.js
