A simple library that can load and process images (in asynchronous) in Unity.
Based on Unimage Native.
Open Unity Editor > Window > Package Manager > Add from Git URL:
https://github.com/Klrohias/unimage-unity.git#0.1.3
using Unimage;
...
var processor = new UnimageProcessor();
processor.Load(uwr.downloadHandler.data);
processor.Resize(100, 100);
uiRawImage.texture = processor.GetTexture();
// or you can use async api
var processor = new UnimageProcessor();
await processor.LoadAsync(await File.ReadAllBytesAsync("..."));
await processor.ResizeAsync(100, 100);
uiRawImage.texture = await processor.GetTextureAsync();
