public static byte[] EncodeArrayToJPG (Array input, Experimental.Rendering.GraphicsFormat format, uint width, uint height, uint rowBytes, int quality);

パラメーター

input The byte array to convert.
format The pixel format of the image data.
width The width of the image data in pixels.
height The height of the image data in pixels.
rowBytes The length of a single row in bytes.
quality 1..100(デフォルト75)でエンコードする JPG の画質

説明

Encodes this array into JPG format.

The returned byte array is the JPG "file". You can write them to disk to get the JPG file, send them over the network, etc.

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.

This method is thread safe.

Passing rowBytes of 0 will calculate the row length in bytes automatically.

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 bytes in JPG format byte[] bytes = ImageConversion.EncodeArrayToJPG(tex.GetRawTextureData(), tex.graphicsFormat, (uint)width, (uint)height); Object.Destroy(tex);

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