用于创建 Animated PNG（Animated Portable Network Graphics）图像文件格式的 API 是为希望生成引人入胜的动画图像的开发者提供的动态工具。通过可自定义的选项，如帧持续时间和循环次数，此 API 允许根据特定需求微调动画内容。无论是创建吸引人的网页图形还是交互式视觉效果，您都可以利用此 API 无缝地将 APNG 图像集成，并对动画参数进行精确控制。
## 构造函数

| 构造函数 | 描述 |
| --- | --- |
| [ApngOptions()](#ApngOptions--) | 初始化 [ApngOptions](../../com.aspose.imaging.imageoptions/apngoptions) 类的新实例。 |
| [ApngOptions(ApngOptions apngOptions)](#ApngOptions-com.aspose.imaging.imageoptions.ApngOptions-) | 初始化 `ApngOptions` 类的新实例。 |
## 方法

| 方法 | 描述 |
| --- | --- |
| [getNumPlays()](#getNumPlays--) | 获取动画循环的次数。 |
| [setNumPlays(int value)](#setNumPlays-int-) | 设置动画循环的次数。 |
| [getDefaultFrameTime()](#getDefaultFrameTime--) | 获取默认帧持续时间。 |
| [setDefaultFrameTime(long value)](#setDefaultFrameTime-long-) | 设置默认帧持续时间。 |

## Example: The following example shows how to export to APNG file format.

``` java

import com.aspose.imaging;
import com.aspose.imaging.imageoptions;

try (Image image = Image.load("Animation1.webp"))
{
    // 默认导出为具有无限动画循环的 APNG 动画
    image.save("Animation1.webp.png", new ApngOptions());
    // 设置动画循环
    ApngOptions options = new ApngOptions();
    options.setNumPlays(5);
    image.save("Animation2.webp.png", options); // 5 cycles
}
```


## Example: The following example shows how to export apng APNG file format from other non-animated multi-page format.

``` java
import com.aspose.imaging;
import com.aspose.imaging.imageoptions;

try (Image image = Image.load("img4.tif"))
{
    // 设置默认帧持续时间
    ApngOptions options = new ApngOptions();
    options.setDefaultFrameTime(500);
    image.save("img4.tif.500ms.png", options); // 500 ms
    options.setDefaultFrameTime(250);
    image.save("img4.tif.250ms.png", options); // 250 ms
}
```
