Matrix3x2F::Skew method (d2d1helper.h)

  • Article

Creates a skew transformation that has the specified x-axis and y-axis values and center point.

Syntax

Matrix3x2F Skew(
  FLOAT         angleX,
  FLOAT         angleY,
  D2D1_POINT_2F center
);

Parameters

angleX

Type: FLOAT

The x-axis skew angle, which is measured in degrees counterclockwise from the y-axis.

angleY

Type: FLOAT

The y-axis skew angle, which is measured in degrees clockwise from the x-axis.

center

Type: D2D1_POINT_2F

The point about which the skew is performed.

Return value

Type: Matrix3x2F

The new skew transformation.

Remarks

The typical y-axis skew means skews the angle in degrees counterclockwise from the x-axis. However, because the y-axis in Direct2D is inverted, the y-axis skew angle in Direct2D means skew the angle in degrees clockwise from the x-axis.

For example, the following illustration shows the rectangle skewed with y-axis skew angle of 30 degrees. Notice that the angle is 30 degrees clockwise from the x-axis.
