○イメージをデータ形式で設定する例

String ^ImageFile;
FileStream^ fs = gcnew FileStream(ImageFile,FileMode::Open, FileAccess::Read, FileShare::Read );
int imageLength = (int)fs->Length;
int readSize;
array<Byte> ^ imageData = gcnew array<Byte>(imageLength);
readSize = fs->Read(imageData, 0, imageLength);
fs->Close();
pin_ptr<Byte> pNative = &imageData[0];

//イメージデータを描画します。
ret = jvSetFieldImageData(pid, "IMAGE_2", imageLength, pNative);
pNative = nullptr;
