◆ AbandonCurrentFigure()

void ON_OutlineAccumulator::AbandonCurrentFigure ( )

◆ ActiveFigureCurrentPoint()

const ON_OutlineFigurePoint ON_OutlineAccumulator::ActiveFigureCurrentPoint ( ) const

Expert user tool for getting the current point of the figure being accumulated.

◆ ActiveFigureStartPoint()

const ON_OutlineFigurePoint ON_OutlineAccumulator::ActiveFigureStartPoint ( ) const

Expert user tool for getting the start point of the figure currently being accumulated.

◆ AppendCubicBezier()

bool ON_OutlineAccumulator::AppendCubicBezier	(	ON_2fPoint	cv1,
		ON_2fPoint	cv2,
		ON_2fPoint	cv3
	)

Description: Appends a cubic (degree = 3, order = 4) bezier to the current figure. The cubic bezier begins at the current_point and ends at cv3. The cubic bezier has four control points (current point, cv1, cv2, cv3). Parameters: cv1 - [in] cv2 - [in] cv3 - [in] end of the cubic bezier.

◆ AppendLine()

bool ON_OutlineAccumulator::AppendLine ( ON_2fPoint line_end_point )

Description: Appends a line segment to the current figure. The line segment begins at the current_point and ends at line_end_point. Parameters: line_end_point - [in]

◆ AppendQuadraticBezier()

bool ON_OutlineAccumulator::AppendQuadraticBezier	(	ON_2fPoint	cv1,
		ON_2fPoint	cv2
	)

Description: Appends a quadratic (degree = 2, order = 3) bezier to the current figure. The quadratic bezier begins at the current_point and ends at cv2. The quadratic bezier has three control points (current point, cv1, cv2, cv3). Parameters: cv1 - [in] cv2 - [in] end of the quadratic bezier.

◆ BeginFigure()

bool ON_OutlineAccumulator::BeginFigure	(	ON_OutlineFigurePoint::Type	point_type,
		ON_2fPoint	figure_starting_point
	)

Tools for adding figures to the outline Description: Begins a figure. A glyph outline has zero or more figures. Parameters: point_type - [in] One of ON_OutlineFigurePoint::Type::BeginFigureUnknown ON_OutlineFigurePoint::Type::BeginFigureFilled ON_OutlineFigurePoint::Type::BeginFigureHollow ON_OutlineFigurePoint::Type::BeginFigureOpen ON_OutlineFigurePoint::Type::BeginFigureClosed figure_starting_point - [in] First point in the figure.

◆ BeginGlyphOutline()

bool ON_OutlineAccumulator::BeginGlyphOutline	(	ON__UINT32	font_units_per_em,
		ON_OutlineFigure::Type	figure_type,
		ON_Outline *	destination_outline
	)

Parameters: font_units_per_em - [in] This is the height and width of the square font design grid. In TrueType fonts, font_units_per_em is often a power of two and generally 1024 or 2048. In OpenType fonts, font_units_per_em is often 1000. In PostScript fonts, font_units_per_em is often 1000. figure_type - [in] True if the glyphs are single stroke and open glyphs should not be closed. coordinate_type - [in] ON_OutlineAccumulator::Coordinate::Integer The points passed to the figure drawing methods will be ON_2iPoint values. The resulting outline will contain ON_2iPoint values. ON_OutlineAccumulator::Coordinate::Float The points passed to the figure drawing methods will be ON_2fPoint values. The resulting outline will contain ON_2fPoint values. ON_OutlineAccumulator::Coordinate::Float The points passed to the figure drawing methods will be ON_2fPoint values that should be rounded to the nearest integer. The resulting outline will contain ON_2iPoint values. bAccumulatePoints - [in] True if the points should be accumulated in the m_outline_points[] array. False if the points are not accumulated. In all cases, the outline bounding box is calculated. Remarks: Typically both the width and the height of the 'M' glyph in the font are less than font_units_per_em.

◆ CurrentFigureAccumulating()

const bool ON_OutlineAccumulator::CurrentFigureAccumulating ( ) const

◆ CurrentFigurePoint()

const ON_OutlineFigurePoint ON_OutlineAccumulator::CurrentFigurePoint ( ) const

◆ CurrentFigurePointCount()

unsigned int ON_OutlineAccumulator::CurrentFigurePointCount ( ) const

Returns: Number of points in the current figure.

◆ CurrentFigurePreviousPoint()

const ON_OutlineFigurePoint ON_OutlineAccumulator::CurrentFigurePreviousPoint ( ) const

◆ CurrentFigureStartPoint()

const ON_OutlineFigurePoint ON_OutlineAccumulator::CurrentFigureStartPoint ( ) const

◆ EndFigure()

bool ON_OutlineAccumulator::EndFigure ( ON_OutlineFigurePoint::Type point_type )

Description: Terminates a figure that was started with the previous call to BeginFigure2i() or BeginFigure2f(). The locations of the figure's starting and final points are always identical. The point_type parameter is used to indicate if a line segment from the starting point to the final point is included in the figure. Parameters: point_type - [in] One of ON_OutlineFigurePoint::Type::EndFigureUnknown If FigureType() is SingleStroke, this value is treated as if it were ON_OutlineFigurePoint::Type::EndFigureOpen. Otherwise, the final point in the figure will have this type. ON_OutlineFigurePoint::Type::EndFigureClosed If FigureType() is SingleStroke is true, this value is treated as if it were ON_OutlineFigurePoint::Type::EndFigureOpen. Otherwise, the final point in the figure will have this type. ON_OutlineFigurePoint::Type::EndFigureOpen The final point in the figure will have this type.

◆ EndOutline() [1/2]

bool ON_OutlineAccumulator::EndOutline ( )

Returns: EndOutline(false,ON_Outline::DefaultOuterOrientation);

◆ EndOutline() [2/2]

bool ON_OutlineAccumulator::EndOutline	(	bool	bNegatePointY,
		ON_OutlineFigure::Orientation	outer_orientation
	)

Parameters: bNegatePointY - [in] If true, the y coordinate of the accumulated points is negated. This is done before any orientation adjustments are performed. outer_orientation - [in] If outer_orientation is ON_OutlineFigure::Orientation::Clockwise, or ON_OutlineFigure::Orientation::CounterClockwise, then the figures are oriented so that outer boundaries have the specified orientation. Otherwise this parameter is ignored.

◆ ErrorCount()

unsigned int ON_OutlineAccumulator::ErrorCount ( ) const

Returns: Number of input errors that have occurred. Remarks: When an error occurs, the current figure is terminated.

◆ UnitsPerEM()

ON__UINT32 ON_OutlineAccumulator::UnitsPerEM ( ) const

Returns: Outline design units per em.
