// ...

Explicit destruction

// ...
imageInstance.dispose()

C#

using (var imageInstance = new Image())
{
   // ...
}

Explicit destruction

var imageInstance = new Image()
// ...
imageInstance.Dispose()

Java

try (Image imageInstance = new Image()) {
// ...
}

Explicit destruction

// ...
imageInstance.close();

Swift

private var imageInstance: Image? = nil
imageInstance = try Image()

C

ID3_FACE_IMAGE hImage{};
int err = id3FaceImage_Initialize(&hImage);
if (err == ID3_SUCCESS) {
    // ...
