public static NativeArray<byte> EncodeNativeArrayToTGA (NativeArray<T> input, Experimental.Rendering.GraphicsFormat format, uint width, uint height, uint rowBytes);

파라미터

input The native 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.

설명

Encodes this native array into TGA format.

This function returns a NativeArray<byte> which is the TGA data. Write this data to disk to get the data in the TGA file format.

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.

// 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 NativeArray<byte> imageBytes = new NativeArray<byte>(tex.GetRawTextureData(), Allocator.Temp); var bytes = ImageConversion.EncodeNativeArrayToTGA(imageBytes, 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.ToArray()); } }
