Matrix3x2F::Scale(D2D1_SIZE_F,D2D1_POINT_2F) method (d2d1helper.h)

Creates a scale transformation that has the specified scale factors and center point.

Syntax

Matrix3x2F Scale(
  D2D1_SIZE_F   size,
  D2D1_POINT_2F center
);

Parameters

size

Type: D2D1_SIZE_F

The x-axis and y-axis scale factors of the scale transformation.

center

Type: D2D1_POINT_2F

The point about which the scale is performed.

Return value

Type: Matrix3x2F

The new scale transformation.

Remarks

This method creates a scale transformation for the specified centerPoint and scale factors. The scale factors are stored as an ordered pair in the D2D1_SIZE_F structure. If you prefer to list each scale factor as a parameter, call the other Scale method.

The following illustration shows the size of the square increased to 130% in each dimension. The center point for the scaling is the upper-left corner of the square.
