TTMSFNCGraphicsPath Class

Framework-neutral vector graphics path that accumulates move, line, curve, arc, and close operations. Pass to TTMSFNCGraphics.DrawPath or FillPath to render the path, or use as a clip region.

API unit family: TMSFNCGraphicsTypes Inherits from: TPersistent

Syntax

TTMSFNCGraphicsPath = class(TPersistent)

Properties

Name	Description
Clippable	When True, this path is used as a clipping region rather than a drawable shape.
Count	The number of points in the path.
PathData	The underlying list of path point records.
Points	Provides indexed access to the individual path points.

Methods

Name	Description
AddArc	Appends an arc as a path segment.
AddEllipse	Appends an ellipse inscribed within ARect as a closed sub-path.
AddLine	Adds a straight line segment from StartPoint to EndPoint.
AddPath	Appends all points and segments of another path to this path.
AddPolygon	Appends all vertices of APolygon as a sequence of line-to operations.
AddRectangle	Appends a rectangle (optionally with rounded corners) as a closed sub-path.
ApplyMatrix	Transforms every point in the path by a transformation matrix.
Clear	Removes all points from the path, resetting it to an empty state.
ClosePath	Closes the current sub-path by adding a line back to its start point.
CreateBezier	Samples evenly-spaced points along a Bezier curve and returns them as a polygon.
CurveTo	Adds a cubic Bezier curve from the current position to EndPoint using the two given control points.
Flatten	Approximates all curves in the path with line segments.
FlattenToPolygon	Approximates all curves with line segments and outputs the result as a flat polygon array.
GetBounds	Returns the tightest bounding rectangle that encloses all path points.
IsClippable	Tests whether this path has been flagged as a clipping path.
IsPointVisible	Tests whether point P lies within the bounding region of the path.
IsRectVisible	Tests whether rectangle R intersects the bounding region of the path.
LastPoint	Returns the last point that was added to the path.
LineTo	Adds a straight line segment from the current position to P.
MoveTo	Moves the current drawing position to P without drawing a line, starting a new sub-path.
PointOnBezier	Evaluates a cubic Bezier segment at parameter T (0.0–1.0) using pre-computed coefficients.
QuadCurveTo	Adds a quadratic Bezier curve from the current position to EndPoint using one control point.
SmoothCurveTo	Adds a smooth cubic Bezier curve, automatically mirroring the previous segment's second control point.
