public static bool LoadImage(Texture2D tex, byte[] data, bool markNonReadable);

Parameters

dataThe byte array containing the image data to load.
markNonReadableSet to false by default, pass true to optionally mark the texture as non-readable.
texThe texture to load the image into.

Returns

bool Returns true if the data can be loaded, false otherwise.

Description

Loads PNG/JPG image byte array into a texture.

This function replaces texture contents with new image data. After LoadImage, texture size and format might change. JPG files are loaded into RGB24 format, PNG files are loaded into RGBA32 format. If texture format before calling LoadImage is DXT1 or DXT5, then the loaded image will be DXT-compressed (into DXT1 for JPG images and DXT5 for PNG images). If the platform is not able to perform runtime compression then false will be returned.

Texture will be uploaded to the GPU automatically; there's no need to call Apply.

Texture2D tex = new Texture2D(2, 2); tex.LoadImage(imageAsset.bytes); GetComponent<Renderer>().material.mainTexture = tex; } }
