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


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. The default is 0, which means Unity calculates the length automatically.


Encodes this array into PNG format.

This function returns a byte array which is the PNG 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. The encoded PNG data will be either 8bit grayscale, RGB or RGBA (depending on the passed in format). For single-channel red textures ( R8, R16, RFloat and RHalf ), the encoded PNG data will be in grayscale. PNG data will not contain gamma correction or color profile information.

This method is thread safe.

// Read the screen contents into the texture tex.ReadPixels(new Rect(0, 0, width, height), 0, 0); tex.Apply();

// Encode the bytes in PNG format byte[] bytes = ImageConversion.EncodeArrayToPNG(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.png", bytes); } }
