Encoder.SaveFlag Encoder.SaveFlag Encoder.SaveFlag Encoder.SaveFlag Field

定義

フラグ保存パラメーター カテゴリのグローバル一意識別子を使用して初期化される Encoder オブジェクトを表します。Represents an Encoder object that is initialized with the globally unique identifier for the save flag parameter category.

public: static initonly System::Drawing::Imaging::Encoder ^ SaveFlag;

 staticval mutable SaveFlag : System.Drawing.Imaging.Encoder
Public Shared ReadOnly SaveFlag As Encoder 

フィールド値

次の例では、作成 3Bitmapオブジェクト: JPEG ファイル、および PNG ファイルからの BMP ファイルから 1 つ。The following example creates three Bitmap objects: one from a BMP file, one from a JPEG file, and one from a PNG file. コードでは、1 つのマルチ フレーム TIFF ファイルにすべての 3 つのイメージを保存します。The code saves all three images in a single, multiple-frame TIFF file.

パラメーターがカプセル化されたイメージ エンコーダー パラメーターを渡すと、ときに、EncoderParameterオブジェクト。When you pass a parameter to an image encoder, the parameter is encapsulated in an EncoderParameter object. フィールドの 1 つ、EncoderParameterオブジェクトは、パラメーターのカテゴリを指定する GUID です。One of the fields of the EncoderParameter object is a GUID that specifies the category of the parameter. 静的フィールドを使用して、Encoderを取得するクラス、Encoder適切なカテゴリのパラメーターを格納しています。Use the static fields of the Encoder class to retrieve an Encoder that contains parameters of the desired category.

組み込まれているイメージ エンコーダーGDI+GDI+パラメーターを受け取る複数のカテゴリに属していること。The image encoders that are built into GDI+GDI+ receive parameters that belong to several categories. 次の表に、すべてのカテゴリと各カテゴリに関連付けられている GUID。The following table lists all the categories and the GUID associated with each category.
