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 JPG quality to encode with. The range is 1 through 100. 1 is the lowest quality. The default is 75.

描述

将该纹理编码为 JPG 格式。

This function returns a byte array which is the JPG file data. You can store the encoded data as a file or send it over the network without further processing.

This function does not work on any compressed format. Texture.isReadable must be true. The encoded JPG data will be either 8bit grayscale, RGB or RGBA (depending on the passed in format).

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 = ImageConversion.EncodeToJPG(tex); Object.Destroy(tex);

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