説明

Loads PNG/JPG (or supported format) image byte array into a texture.

The LoadImage function replaces texture contents with new image data. This function can also change texture size and format. JPG files are loaded into RGB24 format, PNG files are loaded into ARGB32 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.

This function loads the texture data without gamma correction. If the texture data uses the sRGB color space, you must use an sRGB Texture2D object for correct rendering results. Likewise, if the texture data uses the linear color space, then you must use a linear Texture2D object. (A Texture2D object is sRGB if its linear constructor parameter was false, which is the default, and linear if the parameter was set to true.)

Note: In previous versions of Unity, texture data from all PNG textures containing a gAMA block was returned in gamma 2.0 space. If you want to retain this old behavior, for example when working with older projects that dynamically load textures using LoadImage, set ImageConversion.EnableLegacyPngGammaRuntimeLoadBehavior to true.

Texture size does not matter, since // LoadImage will replace with with incoming image size. Texture2D tex = new Texture2D(2, 2); tex.LoadImage(imageAsset.bytes); GetComponent<Renderer>().material.mainTexture = tex; } }
