◆ transformPoint()

static FloatPoint Graphics::TransformTools::transformPoint	(	FloatPoint	point,
		const float	rotate,
		const Common::Point &	zoom,
		const bool	mirrorX = `false`,
		const bool	mirrorY = `false`
	)

static

Basic transform (scale + rotate) for a single point

Parameters

point	the point on which the transform is to be applied
rotate	the angle in degrees
zoom	zoom x,y in percent
mirrorX	flip along the vertical axis?
mirrorY	flip along the horizontal axis?

static Common::Rect Graphics::TransformTools::newRect	(	const Common::Rect &	oldRect,
		const TransformStruct &	transform,
		Common::Point *	newHotspot
	)

static

Returns: the smallest rect that can contain the transformed sprite and, as a side-effect, "newHotspot" will tell you where the hotspot will have ended up in the new rect, for centering.
