Declaration

public static byte[] EncodeArrayToTGA(Array array, Experimental.Rendering.GraphicsFormat format, uint width, uint height, uint rowBytes);

Parameters

array 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.

Description

Encodes this array into TGA format.

The TGA encoded texture is returned as a byte array. You can store the encoded texture as a file or send it over the network without further processing.

The encoded TGA data is not compressed and contains an alpha channel for RGBA32, ARGB32 textures, and no alpha channel for RGB24 textures. For single-channel red textures ( R8, R16, RFloat and RHalf ), the encoded TGA 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 TGAScreenSaver : MonoBehaviour { // Take a shot immediately IEnumerator Start() { yield return SaveScreenTGA(); }

// 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 TGA format byte[] bytes = ImageConversion.EncodeArrayToTGA(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.tga", bytes); } }
