Texture2D.LoadImage

パラメーター

戻り値

bool データが読み込み可能であれば True、不可であれば False を返します。

説明

byte 配列からテクスチャへ変換し PNG/JPG 画像を読み込みます

この機能は、新たな画像データとテクスチャの内容を置き換えます。 ロードイメージの後は、テクスチャサイズと形式が変更される可能性があります。JPG ファイルは、RGB24 形式に読み込まれます。 PNG ファイルは ARGB32 形式に読み込まれます。 LoadImage を呼び出す前にテクスチャ形式は DXT1 か DXT5 であれば、 読み込まれたイメージは DXT 圧縮されます。（ DXT5 に対する PNG 画像や DXT1 に対する JPG 画像） プラットフォームが実行時に圧縮を行うことができない場合、false が返される。

テクスチャを自動的に GPU にアップロードします。Apply を呼び出す必要はありません。

using UnityEngine;

public class ExampleClass : MonoBehaviour {
    // Load a .jpg or .png file by adding .bytes extensions to the file
    // and dragging it on the imageAsset variable.
    public TextAsset imageAsset;
    public void Start() {
        // Create a texture. 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;
    }
}
