# generateStickerThumbnail

> 生成贴纸缩略图。

```ts theme={null}
static generateStickerThumbnail(
  stickerPath: string,
  thumbnailPath: string,
  size: Size
): Promise<APIResponse<boolean>>;
```

**参数**

| 参数              | 类型                                                      | 说明                                                                                                                       |
| --------------- | ------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------ |
| `stickerPath`   | `string`                                                | 贴纸源文件路径                                                                                                                  |
| `thumbnailPath` | `string`                                                | 缩略图输出路径（通常为 `.png`）                                                                                                      |
| `size`          | [`Size`](/zh/api-reference/supernote-plugin/types/size) | 缩略图尺寸（需与原图保持等比例），可以通过 [`getStickerSize`](/zh/api-reference/supernote-plugin/plugin-comm-api/get-sticker-size)这个接口获取贴纸的尺寸 |

**返回**

* [`APIResponse<boolean>`](/zh/api-reference/supernote-plugin/types/api-response)：
  `result === true` 表示生成缩略图成功

## 示例

```ts wrap theme={null}
import { PluginCommAPI } from 'sn-plugin-lib';

/**
 * 生成贴纸缩略图的示例。
 */
export async function exampleGenerateStickerThumbnail() {
  const stickerPath = '/storage/emulated/0/Note/stickers/demo.sticker';
  const thumbnailPath = '/storage/emulated/0/Note/stickers/demo_thumb.png';
  const sizeRes = await PluginCommAPI.getStickerSize(stickerPath);
  if (!sizeRes.success || !sizeRes.result) {
    throw new Error(sizeRes.error?.message ?? 'getStickerSize 调用失败');
  }
  const size = sizeRes.result;

  const res = await PluginCommAPI.generateStickerThumbnail(stickerPath, thumbnailPath, size);
  if (!res.success) {
    throw new Error(res.error?.message ?? 'generateStickerThumbnail 调用失败');
  }
  return res.result;
}
