public static bool LoadImage (Texture2D tex, byte[] data, bool markNonReadable= false);

参数

data 包含要加载的图像数据的字节数组。
markNonReadable 默认设置为 false,传递 true 可以有选择地将该纹理标记为不可读。
tex 要将图像加载到的纹理。

返回

bool 如果可以加载数据,则返回 true,否则返回 false。

描述

将 PNG/JPG 图像字节数组加载到纹理中。

该函数使用新图像数据替换纹理内容。调用 LoadImage 后, 纹理的大小和格式可能会更改。JPG 文件加载为 RGB24 格式, PNG 文件加载为 RGBA32 格式。如果调用 LoadImage 前的纹理格式为 DXT1DXT5, 则对加载的图像进行 DXT 压缩(对于 JPG 图像,使用 DXT1;对于 PNG 图像,使用 DXT5)。 如果平台无法执行运行时压缩,则返回 false。

纹理将自动上传到 GPU;没有必要调用 Apply

using UnityEngine;

public class ExampleClass : MonoBehaviour { // Load a .jpg or .png file by adding .bytes extensions to the file // and dragging it on the imageAsset variable. public TextAsset imageAsset; public void Start() { // Create a texture. Texture size does not matter, since // LoadImage will replace with with incoming image size. Texture2D tex = new Texture2D(2, 2); tex.LoadImage(imageAsset.bytes); GetComponent<Renderer>().material.mainTexture = tex; } }
