ImageConversion.EncodeNativeArrayToPNG

매뉴얼로 전환
public static NativeArray<byte> EncodeNativeArrayToPNG (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. The default is 0, which means Unity calculates the length automatically.

설명

Encodes this native array into PNG format.

This function returns a NativeArray<byte> which is the PNG 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.
