Function Documentation

KEYTransformation libetonyek::transformations::center	(	double	width,
		double	height
	)

Translate to the center of viewport.

• [in] width width of the viewport.
• [in] height height of the viewport.

  Returns

  the transformation

Referenced by libetonyek::makeTransformation().

KEYTransformation libetonyek::transformations::flip	(	bool	horizontal,
		bool	vertical
	)

Flip horizontally and/or vertically.

• [in] horizontal flip horizontally.
• [in] vertical flip vertically.

  Returns

  the transformation

Referenced by libetonyek::makeArrowPath(), libetonyek::makeDoubleArrowPath(), and libetonyek::makeTransformation().

KEYTransformation libetonyek::transformations::origin	(	double	width,
		double	height
	)

Translate from the center of viewport to the origin.

This is inverse operation to center().

• [in] width width of the viewport.
• [in] height height of the viewport.

  Returns

  the transformation

Referenced by libetonyek::makeTransformation().

KEYTransformation libetonyek::transformations::rotate

(

double

angle

)

Rotate counterclockwise around origin.

• [in] angle rotation angle in radians. 0 is at the x axis on the right side.

  Returns

  the transformation

Referenced by libetonyek::makeStarPath(), and libetonyek::makeTransformation().

KEYTransformation libetonyek::transformations::scale	(	double	ratioX,
		double	ratioY
	)

Scale along x and/or y axis.

• [in] ratioX scale ratio along x axis.
• [in] ratioY scale ratio along y axis.

  Returns

  the transformation

Referenced by flip().

KEYTransformation libetonyek::transformations::shear	(	double	angleX,
		double	angleY
	)

Shear along x and/or y axis.

• [in] angleX shear angle along x axis.
• [in] angleY shear angle along y axis.

  Returns

  the transformation

Referenced by libetonyek::makeTransformation().

KEYTransformation libetonyek::transformations::translate	(	double	offsetX,
		double	offsetY
	)

Translate along x and/or y axis.

• [in] offsetX translation offset along x axis.
• [in] offsetY translation offset along y axis.

  Returns

  the transformation

Referenced by center(), libetonyek::makeArrowPath(), libetonyek::makeCalloutPath(), libetonyek::makeDoubleArrowPath(), libetonyek::makePolygonPath(), libetonyek::makeRoundedRectanglePath(), libetonyek::makeStarPath(), libetonyek::makeTransformation(), and origin().
