パラメーター

名前	型	方向	説明
graphics	GpGraphics*	inout	再生先のGDI+グラフィックスオブジェクトへのポインタ。
metafile	GpMetafile*	in	列挙対象のメタファイルオブジェクトへのポインタ。
destPoints	PointF*	in	描画先の平行四辺形を定義する点配列(PointF)。3点を指定する。
count	INT	in	destPoints配列内の点の個数。通常は3。
srcRect	RectF*	in	メタファイルから切り出す元矩形(RectF)へのポインタ。
srcUnit	Unit	in	srcRectの座標単位を示すUnit列挙値。
callback	INT_PTR	in	各メタファイルレコードごとに呼ばれるEnumerateMetafileProcへのアドレス。
callbackData	void*	inout	コールバックへ渡す任意データへのポインタ。NULL可。
imageAttributes	GpImageAttributes*	in	色調整など描画属性を指定するImageAttributesへのポインタ。NULL可。
