GRE::VIEWPOS::VIEWPOS ( )

GRE::VIEWPOS::~VIEWPOS ( )

const SPATREF::COORDREFSYS& GRE::VIEWPOS::GetCenterCRS ( ) const [inline]

Get CRS for center point.

const DPOINT2D& GRE::VIEWPOS::GetCenterPoint ( ) const [inline]

Get center point.

double GRE::VIEWPOS::GetMapScale ( ) const [inline]

Get map scale.

const VIEWPLACE& GRE::VIEWPOS::GetPlace ( ) const [inline]

Get view "place".

const TRANS2D_AFFINE& GRE::VIEWPOS::GetTransViewDevice ( ) const [inline]

Get transformation from "view" to rendering "device".

const DPOINT2D& GRE::VIEWPOS::GetZoom ( ) const [inline]

Get zoom value (1.0 is full view).

void GRE::VIEWPOS::ScaleZoom ( double scale ) [inline]

Apply scale to zoom value.

void GRE::VIEWPOS::SetCenterPoint ( const DPOINT2D & CenterPoint ) [inline]

Set center point.

void GRE::VIEWPOS::SetCenterPoint	(	const SPATREF::COORDREFSYS &	CenterCRS,
		const DPOINT2D &	CenterPoint
	)			`[inline]`

Set center CRS and point.

void GRE::VIEWPOS::SetMapScale ( double MapScale ) [inline]

Set map scale.

void GRE::VIEWPOS::SetPlace ( const VIEWPLACE & ViewPlace ) [inline]

Set view "place".

void GRE::VIEWPOS::SetTransViewDevice ( const TRANS2D_AFFINE & TransViewDevice ) [inline]

Set tranformation from "view" to rendering "device".

void GRE::VIEWPOS::SetZoom ( const DPOINT2D & zoom ) [inline]

Set zoom.

void GRE::VIEWPOS::SetZoom ( double zoom ) [inline]

Set zoom with equal X/Y values.

void GRE::VIEWPOS::ValidateZoom ( bool AllowDifferXY )

Validate zoom based on whether allowing different X and Y values.
