public static byte[] EncodeToJPG (Texture2D tex, int quality);
public static byte[] EncodeToJPG (Texture2D tex);

参数

tex 要转换的文本纹理。
quality 要编码的 JPG 品质(范围为 1..100,默认为 75)。

描述

将该纹理编码为 JPG 格式。

返回的字节数组为 JPG“文件”。您可以将它们写入磁盘以获取 JPG 文件, 或通过网络发送等。

This function works only on uncompressed, non-HDR texture formats. You must enable the texture's Read/Write Enabled flag in the Texture Import Settings. The encoded JPG data will have no alpha channel, and for single-channel red textures ( R8, R16, RFloat and RHalf ) the encoded JPG data will be in 8-bit grayscale.

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

IEnumerator SaveScreenJPG() { // 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 JPG format byte[] bytes = tex.EncodeToJPG(); Object.Destroy(tex);

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