定義

定義可在 2-D 平面轉換的功能。Defines functionality that enables transformations in a 2-D plane. 轉換包含旋轉 (RotateTransform)、縮放 (ScaleTransform)、扭曲 (SkewTransform) 和平移 (TranslateTransform)。Transformations include rotation (RotateTransform), scale (ScaleTransform), skew (SkewTransform), and translation (TranslateTransform). 此類別階層與 Matrix 結構的差別在於其為類別,而且支援動畫和列舉語意。This class hierarchy differs from the Matrix structure because it is a class and it supports animation and enumeration semantics.

備註

使用MatrixTransform類別來建立自訂的轉換,不會提供RotateTransformScaleTransformSkewTransform,和TranslateTransform類別。Use the MatrixTransform class to create custom transformations that are not provided by the RotateTransform, ScaleTransform, SkewTransform, and TranslateTransform classes.

A 2-D2-D x-y 平面使用 3x3 矩陣轉換。A 2-D2-D x-y plane uses a 3x3 matrix for transformations. 您可以將仿射轉換矩陣,以形成線性轉換,例如旋轉及傾斜 (切變) 緊接著轉譯。You can multiply affine transformation matrices to form linear transformations, such as rotation and skew (shear) that are followed by translation.

非仿射轉換矩陣有等於 (0,0,1),其最後一個資料行因此,您只需要前兩個資料行中指定的成員。An affine transformation matrix has its final column equal to (0, 0, 1); therefore, you only have to specify the members in the first two columns.

A Windows Presentation Foundation (WPF)Windows Presentation Foundation (WPF) Matrix具有下列結構:A Windows Presentation Foundation (WPF)Windows Presentation Foundation (WPF) Matrix has the following structure:

M11 M12 00
M21 M22 00
OffsetX OffsetY 11

在最後一個資料列中,成員OffsetXOffsetY,代表翻譯值。The members in the last row, OffsetX and OffsetY, represent translation values.

方法和屬性通常會轉換矩陣,可指定為的向量,只有六個成員;不,如下所示:Methods and properties usually specify the transformation matrix as a vector that has only six members; they are as follows:

(M11, M12, M21, M22, OffsetX, OffsetY)(M11, M12, M21, M22, OffsetX, OffsetY)
