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

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.
quality JPG quality to encode with, 1..100 (default 75).

설명

Encodes this native array into JPG format.

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

The encoded JPG data will have no alpha channel, and for single-channel red textures ( R8, R16, RFloat and RHalf ) the encoded JPG data will be in 8-bit grayscale.

This method is thread safe.

Passing rowBytes of 0 will calculate the row length in bytes automatically.
