class glChartCanvas
 

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
xX-coordinate in physical pixels
yY-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 4590 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
rlatLatitude in degrees
rlonLongitude 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 4565 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
vpViewPort containing projection parameters and canvas settings
rlatLatitude in degrees
rlonLongitude 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 4569 of file chcanv.cpp.

◆ GetCanvasRangeMeters()

double ChartCanvas::GetCanvasRangeMeters ( )

Definition at line 2267 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 461 of file chcanv.h.

◆ GetCanvasTrueScale()

double ChartCanvas::GetCanvasTrueScale ( )

  • Click-and-drag panning. Updates chart position continuously during drag.
Parameters
eventThe mouse event to process
Returns
true if event was processed, false to allow focus shifting between canvases.
Note
Interacts with route creation and measurement tools active states

◆ 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
factorThe 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_cursorIf true, zoom operation will be centered on current cursor position. If false, zoom operation centers on current viewport center.
stoptimerIf true, stops any ongoing movement/zoom operations before starting this zoom. If false, allows this zoom to blend with existing operations.

Definition at line 4651 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
factorThe 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

double ChartCanvas::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:

  1. When processing left mouse clicks
  2. During panning operations via mouse dragging
  3. When the OnCursorTrackTimerEvent fires after mouse movement stops
  4. 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.
