Detailed Description

Transformation parameters for non-georeferenced templates, transforming template coordinates to map coordinates.

The parameters are applied to painter in the order

translate
rotate
scale.

So this order is also chosen for the member variables, and thus used in list initialization.

See also: Template::applyTemplateTransform()

Coordinate transformations use the opposite order for the same effect.

Constructor & Destructor Documentation

◆ TemplateTransform() [1/2]

OpenOrienteering::TemplateTransform::TemplateTransform	(	qint32	x,
		qint32	y,
		double	rotation,
		double	scale_x,
		double	scale_y,
		double	shear = `0.0`
	)

inlinenoexcept

Explicit implementation of aggregate initialization.

In C++11, there is no aggregate initialization when default initalizers are present.

Todo:: Remove when we can use C++14 everywhere.

◆ TemplateTransform() [2/2]

OpenOrienteering::TemplateTransform::TemplateTransform ( )

defaultnoexcept

Explicitly defaulted default constructor.

This is needed because of the other explicit constructor.

Todo:: Remove when we can use C++14 everywhere.
