Penting
Beberapa informasi terkait produk prarilis yang dapat diubah secara signifikan sebelum dirilis. Microsoft tidak memberikan jaminan, tersirat maupun tersurat, sehubungan dengan informasi yang diberikan di sini.
Mengembalikan array objek ImageCodecInfo yang berisi informasi tentang encoder gambar yang disertakan dalam GDI+.
public:
static cli::array <System::Drawing::Imaging::ImageCodecInfo ^> ^ GetImageEncoders();
public static System.Drawing.Imaging.ImageCodecInfo[] GetImageEncoders ();
static member GetImageEncoders : unit -> System.Drawing.Imaging.ImageCodecInfo[]
Public Shared Function GetImageEncoders () As ImageCodecInfo()
Mengembalikan
Array objek ImageCodecInfo. Setiap objek ImageCodecInfo dalam array berisi informasi tentang salah satu encoder gambar bawaan.
Contoh
Contoh berikut dirancang untuk digunakan dengan Windows Forms, dan memerlukan PaintEventArgse
, yang merupakan parameter penanganan aktivitas Paint. Kode ini menggunakan metode GetImageEncoders untuk mengambil semua informasi codec untuk semua encoder dan codec gambar yang diinstal, lalu menggambar semua informasi tentang setiap codec ke layar.
