Constructor & Destructor Documentation

Surface()

org.skia.jetski.Surface.Surface ( Bitmap  bitmap )

inline

Create a Surface backed by the provided Bitmap.

The Bitmap must be mutable and its pixels are locked for the lifetime of the Surface.

Definition at line 22 of file Surface.java.

                                  {
        this(CreateBitmapInstance(bitmap));
    }
