  • What is original width and height of gif.A? gif.A 的原始宽度和高度是多少？
  • How many frames?多少帧？
  • In memory each pixel takes 4 bytes.在内存中每个像素占用 4 个字节。 Multiply "4 * original width * height * #frames".乘以“4 * 原始宽度 * 高度 * #frames”。
  • What value do you get?你得到什么价值？ That's what will be needed in cache size to "load the gif".这就是“加载 gif”所需的缓存大小。 Note that it doesn't matter how small the file is on disk;请注意，文件在磁盘上的大小无关紧要； that is "compressed" size.即“压缩”大小。 In memory, it is not compressed.在内存中，它没有被压缩。 It also doesn't matter how small you are downsampling to;下采样到多小也无关紧要； it first loads at the original size [I think].它首先以原始大小加载 [我认为]。

To fix, do EITHER:要修复，请执行以下任一操作：

var config = new FFImageLoading.Config.Configuration()
{
    MaxMemoryCacheSize = 9999999, // Try different values here. Bigger uses more app memory.
};
ImageService.Instance.Initialize(config);
