public static byte[] EncodeToPNG (Texture2D tex);

파라미터

tex The texture to convert.

설명

Encodes this texture 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. Texture.isReadable must be true.

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.
