我的Xamarin.Forms应用程序使用FFimageLoading加载三个GIF。

  • 图片集：3.7MB
  • 背景图片：5.1MB
  • 中文图片：2MB

（这些礼物由DavinciResolve创建）
我的应用程序预加载礼物如下。

public static async void PreloadTutorialGifs()
{
    try
    {
        var targetWidth = 500;
        var targetHeight = 1000;
        await ImageService.Instance.LoadFileFromApplicationBundle("A.gif").Success((info, result) =>
        {
            Debug.WriteLine($"A.gif Preloading finished! Key: {info.CacheKey}");
        })
        .CacheKey("A.gif")
        .DownSample(targetWidth, targetHeight)
        .PreloadAsync();
        await ImageService.Instance.LoadFileFromApplicationBundle("B.gif").Success((info, result) =>
        {
            Debug.WriteLine($"B.gif Preloading finished! Key: {info.CacheKey}");
        })
        .CacheKey("B.gif")
        .DownSample(targetWidth, targetHeight)
        .PreloadAsync();
        await ImageService.Instance.LoadFileFromApplicationBundle("C.gif").Success((info, result) =>
        {
            Debug.WriteLine($"C.gif Preloading finished! Key: {info.CacheKey}");
        })
        .CacheKey("C.gif")
        .DownSample(targetWidth, targetHeight)
        .PreloadAsync();
    }
    catch (Exception ex)
    {
        Console.WriteLine(ex.Message);
        Utility.SendExceptionToCrashlytics(ex);
    }
}

  • gif.A的原始宽度和高度是多少？
  • 多少帧？
  • 在内存中，每个像素占用4个字节。乘以“4 * 原始宽度 * 高度 * 帧数”。
  • 你得到的值是多少？这就是“加载gif”所需要的缓存大小。注意，文件在磁盘上有多小并不重要;这是“压缩”的大小。在内存中，它没有被压缩。它也不在乎你下采样到多小;它首先加载在原来的大小[我想]。

要修复，请执行以下任一操作：

  • 在图像编辑器中，缩小到更小的宽度/高度。
  • 或从内存大小是否大于图像大小？设置FFImageLoader的自定义缓存大小：
var config = new FFImageLoading.Config.Configuration()
{
    MaxMemoryCacheSize = 9999999, // Try different values here. Bigger uses more app memory.
};
ImageService.Instance.Initialize(config);
