Library

Remarks

In GDI+ you can store an affine transformation in a xtd::drawing::drawing_2d::matrix object. Because the third column of a matrix that represents an affine transformation is always (0, 0, 1), you specify only the six numbers in the first two columns when you construct a xtd::drawing::drawing_2d::matrix object. The statement xtd::drawing::drawing_2d::matrix myMatrix = xtd::drawing::drawing_2d::matrix {0, 1, -1, 0, 3, 4} constructs the matrix shown in the following figure.

Composite Transformations

A composite transformation is a sequence of transformations, one followed by the other. Consider the matrices and transformations in the following list:

matrix A	Rotate 90 degrees
matrix B	Scale by a factor of 2 in the x direction
matrix C	Translate 3 units in the y direction

If we start with the point (2, 1) - represented by the matrix [2 1 1] - and multiply by A, then B, then C, the point (2, 1) will undergo the three transformations in the order listed.

[2 1 1]ABC = [-2 5 1]

Rather than store the three parts of the composite transformation in three separate matrices, you can multiply A, B, and C together to get a single 3×3 matrix that stores the entire composite transformation. Suppose ABC = D. Then a point multiplied by D gives the same result as a point multiplied by A, then B, then C.

[2 1 1]D = [-2 5 1]

The following illustration shows the matrices A, B, C, and D.

The fact that the matrix of a composite transformation can be formed by multiplying the individual transformation matrices means that any sequence of affine transformations can be stored in a single xtd::drawing::drawing_2d::matrix object. Caution: The order of a composite transformation is important. In general, rotate, then scale, then translate is not the same as scale, then rotate, then translate. Similarly, the order of matrix multiplication is important. In general, ABC is not the same as BAC.

The xtd::drawing::drawing_2d::matrix class provides several methods for building a composite transformation: xtd::drawing::drawing_2d::matrix::multiply, xtd::drawing::drawing_2d::matrix::rotate, xtd::drawing::drawing_2d::matrix::rotate_at, xtd::drawing::drawing_2d::matrix::scale, xtd::drawing::drawing_2d::matrix::shear, and xtd::drawing::drawing_2d::matrix::translate. The following example creates the matrix of a composite transformation that first rotates 30 degrees, then scales by a factor of 2 in the y direction, and then translates 5 units in the x direction:

matrix my_matrix;
my_matrix.rotate(30);
my_matrix.scale(1, 2, matrix_order::append);
my_matrix.translate(5, 0, matrix_order::append);

scale_y	The vertical shear factor.

Remarks

The transformation applied in this method is a pure shear only if one of the parameters is 0. Applied to a rectangle at the origin, when the shear_y factor is 0, the transformation moves the bottom edge horizontally by shear_x times the height of the rectangle. When the shearX factor is 0, it moves the right edge vertically by shearY times the width of the rectangle. Caution is in order when both parameters are nonzero, because the results are hard to predict. For example, if both factors are 1, the transformation is singular (hence noninvertible), squeezing the entire plane to a single line.

The transformation applied in this method is a pure shear only if one of the parameters is 0. Applied to a rectangle at the origin, when the shear_y factor is 0, the transformation moves the bottom edge horizontally by shear_x times the height of the rectangle. When the shearX factor is 0, it moves the right edge vertically by shearY times the width of the rectangle.
