Detailed Description

ChartCanvas - Main chart display and interaction component.

Manages the visualization of nautical charts and all chart-related user interactions. This class integrates geographic data, user interface elements, and navigation tools into a comprehensive chart viewing experience. It handles everything from chart loading and rendering to user gestures, route planning, and navigation aids.

ChartCanvas uses ViewPort internally to handle the mathematical transformations between geographic and screen coordinates. While ViewPort focuses on the projection math, ChartCanvas manages the actual rendering, user interaction, and application logic.

As a wxWindow subclass, it responds to paint, mouse, keyboard, and other window events, translating them into appropriate chart operations like panning, zooming, and object manipulation.

◆ GetCanvasPixPoint()

void ChartCanvas::GetCanvasPixPoint	(	double	x,
		double	y,
		double &	lat,
		double &	lon
	)

Convert canvas pixel coordinates (physical pixels) to latitude/longitude.

Uses BSB chart geo-referencing for compatible raster charts when conditions permit, otherwise falls back to viewport projection estimation.

Parameters

x	X-coordinate in physical pixels
y	Y-coordinate in physical pixels
lat	[out] Reference to receive the resulting latitude at the given (x, y) coordinates.
lon	[out] Reference to receive the resulting longitude at the given (x, y) coordinates.

See also: ViewPort::GetLLFromPix() for the underlying coordinate transformation.

Definition at line 4560 of file chcanv.cpp.

◆ GetCanvasPointPix()

bool ChartCanvas::GetCanvasPointPix	(	double	rlat,
		double	rlon,
		wxPoint *	r
	)

Convert latitude/longitude to canvas pixel coordinates (physical pixels) rounded to nearest integer.

Uses GetDoubleCanvasPointPixVP internally and rounds results using wxRound (std::lround). This means 3.7 becomes 4, -3.7 becomes -4.

Parameters

rlat	Latitude in degrees
rlon	Longitude in degrees
r	[out] Pointer to wxPoint to receive the canvas pixel coordinates in physical pixels, as rounded integer values.

Returns: true if conversion successful, false if coordinates are invalid or out of bounds.

See also: ViewPort::GetPixFromLL() for the underlying coordinate transformation.

Definition at line 4535 of file chcanv.cpp.

◆ GetCanvasPointPixVP()

bool ChartCanvas::GetCanvasPointPixVP	(	ViewPort &	vp,
		double	rlat,
		double	rlon,
		wxPoint *	r
	)

Convert latitude/longitude to canvas pixel coordinates rounded to nearest integer using specified viewport.

Uses GetDoubleCanvasPointPixVP internally and rounds results using wxRound (std::lround). This means 3.7 becomes 4, -3.7 becomes -4.

Parameters

vp	ViewPort containing projection parameters and canvas settings
rlat	Latitude in degrees
rlon	Longitude in degrees
r	[out] Pointer to wxPoint to receive the canvas pixel coordinates in physical pixels, as rounded integer values.

Returns

true if conversion successful, false if:

Coordinates would be on other side of the world (resulting in NaN)
Resulting pixel values would be too large (>1e6) In these cases, r is set to INVALID_COORD

See also: ViewPort::GetPixFromLL() for the underlying coordinate transformation

Definition at line 4539 of file chcanv.cpp.

◆ GetCanvasRangeMeters()

double ChartCanvas::GetCanvasRangeMeters ( )

Definition at line 2243 of file chcanv.cpp.

◆ GetCanvasScaleFactor()

double ChartCanvas::GetCanvasScaleFactor ( )

inline

Return the number of logical pixels per meter for the screen.

Todo:: The name of this function is misleading. It should be renamed to GetCanvasLogicalPixelsPerMeter() or similar. It looks like some callers are expecting the physical pixels per meter, which is incorrect.

Definition at line 458 of file chcanv.h.

◆ GetCanvasTrueScale()

double ChartCanvas::GetCanvasTrueScale ( )

		double *	lon
	)

Definition at line 4473 of file chcanv.cpp.

◆ GetDisplayScale()

double ChartCanvas::GetDisplayScale ( )

inline

Get the ratio of physical to logical pixel for the display.

On standard displays, one logical pixel equals one physical pixel, so this value is 1.0. On high-DPI/Retina displays, one logical pixel may equal multiple physical pixels:

MacBook Pro Retina: 2.0 (2x2 physical pixels per logical pixel)
Other HiDPI displays: May be 1.5, 1.75, etc.

Definition at line 821 of file chcanv.h.

◆ GetDisplaySizeMM()

inline

Get the width of the screen in millimeters.

◆ GetDoubleCanvasPointPix()

void ChartCanvas::GetDoubleCanvasPointPix	(	double	rlat,
		double	rlon,
		wxPoint2DDouble *	r
	)

Convert latitude/longitude to canvas pixel coordinates (physical pixels) with double precision.

Returns unrounded floating point pixel coordinates. When used with drawing functions that take integer coordinates, values will be truncated.

Parameters

rlat	Latitude in degrees
rlon	Longitude in degrees
r	[out] Pointer to wxPoint2DDouble to receive the canvas pixel coordinates as unrounded floating point values

Definition at line 4480 of file chcanv.cpp.

		wxPoint2DDouble *	r
	)

Convert latitude/longitude to canvas pixel coordinates (physical pixels) with double precision, using specified viewport.

Returns unrounded floating point pixel coordinates. When used with drawing functions that take integer coordinates, values will be truncated.

Parameters

vp	ViewPort containing projection parameters and canvas settings
rlat	Latitude in degrees
rlon	Longitude in degrees
r	[out] Pointer to wxPoint2DDouble to receive the canvas pixel coordinates as unrounded floating point values

◆ ZoomCanvas()

void ChartCanvas::ZoomCanvas	(	double	factor,
		bool	can_zoom_to_cursor = `true`,
		bool	stoptimer = `true`
	)

Perform a smooth zoom operation on the chart canvas by the specified factor.

The zoom can either be centered on the cursor position or the center of the viewport.

Parameters

factor	The zoom factor to apply: factor > 1: Zoom in, e.g. 2.0 makes objects twice as large factor < 1: Zoom out, e.g. 0.5 makes objects half as large
can_zoom_to_cursor	If true, zoom operation will be centered on current cursor position. If false, zoom operation centers on current viewport center.
stoptimer	If true, stops any ongoing movement/zoom operations before starting this zoom. If false, allows this zoom to blend with existing operations.

Definition at line 4621 of file chcanv.cpp.

◆ ZoomCanvasSimple()

void ChartCanvas::ZoomCanvasSimple ( double factor )

Perform an immediate zoom operation without smooth transitions.

This is a simplified version of ZoomCanvas that applies the zoom immediately without animation or cursor-centering logic. Typically used for programmatic zooming.

Parameters

factor

The zoom factor to apply:

factor > 1: Zoom in, e.g. 2.0 makes objects twice as large
factor < 1: Zoom out, e.g. 0.5 makes objects half as large

◆ m_cursor_lat

The latitude in degrees corresponding to the most recently processed cursor position.

This variable does NOT continuously track the mouse cursor position. It is updated only:

During panning operations via mouse dragging
When the OnCursorTrackTimerEvent fires after mouse movement stops
During certain object selection and editing operations

For code that needs the current geographic coordinates under the current mouse pointer, use GetCanvasPixPoint(mouse_x, mouse_y, lat, lon) instead of accessing this variable directly.
