VectorShapeTransform.VectorShapeTransform

VectorShapeTransform constructor

Menginisialisasi instance baru dariVectorShapeTransform kelas.

public VectorShapeTransform()

Contoh

Contoh ini menunjukkan cara mendapatkan dan mengatur properti Transform dan OriginBoxCorners baru dari ShapeOriginSettings di sumber daya Vogk dari FillLayer di file PSD.
