public static void DrawPreviewTexture (Rect position, Texture image, Material mat= null, ScaleMode scaleMode= ScaleMode.StretchToFill, float imageAspect= 0, float mipLevel= -1, Rendering.ColorWriteMask colorWriteMask= ColorWriteMask.All, float exposure= 0);

パラメーター

position テクスチャを描画するスクリーン上の Rect
image 表示する Texture
mat テクスチャを描画するときに使用するマテリアル
scaleMode 描画されるものでアスペクト比が合わないときに画像をどのようにスケーリングするか
imageAspect ソースのイメージに使用するアスペクト比。 0 (デフォルト)の場合はイメージの持つ縦横比が使用されます。
mipLevel The mip-level to sample. If negative, the texture is sampled normally. Sets material's _Mip property.
colorWriteMask Specifies which color components of image will get written. Sets material's _ColorMask property.
exposure Specifies the exposure for the texture. Sets material's _Exposure property.

説明

矩形内にテクスチャを描画します。

If mat is null (the default), an appropriate material will be chosen for a RGBM or doubleLDR lightmap or a normal map and the fallback blit material will be chosen otherwise.
