Namespace: FVIL.Ipl
Assembly: FVILbasic (in FVILbasic.dll) Version: 3.1.0.0 (3.1.0.17)

Syntax

C#
public virtual int Height { get; }
Visual Basic
Public Overridable ReadOnly Property Height As Integer
	Get

Return Value

Type: Int32
画像の高さを返します。
Pointer フィールドを IplImage 構造体にキャストして height フィールドの値をそのまま返します。
Pointer に IntPtr.Zero が設定されている場合は 0 を返します。
