public static byte[] EncodeToTGA (Texture2D tex);

参数

tex 要编码的纹理。

描述

以 TGA 格式对指定的纹理进行编码。

为了让此函数正确执行,必须在 texture import settings 中将纹理的 read/write enabled 标志设置为 true。

TGA 编码的纹理作为字节数组返回。您可以将编码的纹理存储为文件,也可以通过网络发送,无需进一步处理。

该函数仅适用于未压缩的非 HDR 纹理格式。

编码的 TGA 数据未经过压缩,对于 RGBA32ARGB32 纹理,将包含 Alpha 通道,对于 RGB24 纹理,则不包含 Alpha 通道。

// Saves screenshot as TGA file.
using UnityEngine;
using System.Collections;
using System.IO;

public class TGAScreenSaver : MonoBehaviour { // Take a shot immediately IEnumerator Start() { yield return SaveScreenTGA(); }

IEnumerator SaveScreenTGA() { // Read the screen buffer after rendering is complete yield return new WaitForEndOfFrame();

// Create a texture in RGB24 format the size of the screen int width = Screen.width; int height = Screen.height; Texture2D tex = new Texture2D(width, height, TextureFormat.RGB24, false);

// Read the screen contents into the texture tex.ReadPixels(new Rect(0, 0, width, height), 0, 0); tex.Apply();

// Encode the texture in TGA format byte[] bytes = tex.EncodeToTGA(); Object.Destroy(tex);

// Write the returned byte array to a file in the project folder File.WriteAllBytes(Application.dataPath + "/../SavedScreen.tga", bytes); } }
