用于Unity中的图片异步显示加载库 async load and display image in unity

Unity-ImageLoader

用于Unity中的图片异步显示加载库 async load and display image in unity

build in Unity 5.3.4f

用法 Usage

ImageLoader.GetInstance().Display(...);

说明 Instructions

1、可以用于显示的图片类型有：网络图片、本地图片、字节流、Sprite、Texture

Can be used to display the image types are: network image, local image, byte streams, Sprite, Texture

2、带内存及磁盘缓存，默认实现：LRUDiscCache、LRUMemoryCache，也可以自定义实现缓存策略

With memory and disk cache, the default implementation: LRUDiscCache, LRUMemoryCache, can also custom caching strategies

3、默认使用BestHttp请求网络图片，可以自定义实现网络请求

By default use BestHttp to request network images, and you can customize the network request implement

4、图片异步加载使用线程池，默认最大线程数为5

Asynchronous loading images using thread pool，and the default maximum count of threads is 5

unity-imageloader's Issues

Main Thread

My Unity app loads lots of large images from a server, this causes Unity to freeze while decoding and rendering the image becuase this is all done on the main thread.

Does your code still use the main thread to load the images onto textures?

To test have a code like this

void Update()
{
transform.rotate(Vector3(1,0,0)* Time.deltatime*10);
}

Run that while loading several images using your code, see if the object being rotated ever pauses and then resume rotation.

图片多时会卡，最大的瓶颈就在那一行

Texture2D texture = new Texture2D(width, height, TextureFormat.ARGB32, false);
texture.LoadImage(data);

纹理创建和纹理数据载入不能在子线程中做，只能在主线程。一旦下载的图片是png、jpg等格式，LoadImage内部会解码元数据格式到ARGB32，这个是比较花费CPU的，所以图片多一些的时候，卡顿会很明显。好一点的做法考虑在收到http下载的图片数据后。自己写一个解码图片的函数在线程中计算解码。然后在主线程中把解码后的数据直接通过SetPixels或LoadRawTextureData。这样会减少卡顿。

Example please

Hello, I found your project is very promising.
Can you please provide any working sample?
