Leadtools Namespace > LeadMatrix Structure : IsIdentity Property |
[BrowsableAttribute(false)] [XmlIgnoreAttribute()] public bool IsIdentity {get;}
'Declaration
<BrowsableAttribute(False)> <XmlIgnoreAttribute()> Public ReadOnly Property IsIdentity As Boolean
'Usage
Dim instance As LeadMatrix Dim value As Boolean value = instance.IsIdentity
[BrowsableAttribute(false)] [XmlIgnoreAttribute()] public bool IsIdentity {get;}
public boolean isIdentity()
BrowsableAttribute() XmlIgnoreAttribute() get_IsIdentity();
[BrowsableAttribute(false)] [XmlIgnoreAttribute()] public: property bool IsIdentity { bool get(); }
An identity matrix has a value of 1 in coefficients [1,1],[2,2],[3,3] and a value of 0 in the rest of the coefficients. This correlates to setting M11 and M22 to 1 and M12, M21, OffsetX, and OffsetY to 0. In an affine matrix, coefficients [3,1],[3,2],[3.3] are implied to always have the values 0,0,1 respectively.
1 | 0 | 0 |
0 | 1 | 0 |
0 | 0 | 1 |
For an identity matrix, the ToString method returns the string "Identity" instead of the coefficients of the LeadMatrix.
