Path

A 2D geometric path type.

The path is built from a sequence of path commands like moveTo or lineTo etc. Each new command uses the previous end point as its first point except for the moveTo command, that is used to start a new sub path. Each point in a command is tagged with a command type. The shared point between two commands is always tagged for the previous command.

struct Path {

this(this);

~this();

Path moveTo(Scalar x, Scalar y);

Path moveTo(Point point);

Path lineTo(Scalar x, Scalar y);

Path lineTo(Point point);

Path close();

Path quadTo(Scalar x1, Scalar y1, Scalar x2, Scalar y2);

Path cubicTo(Scalar x1, Scalar y1, Scalar x2, Scalar y2, Scalar x3, Scalar y3);

Point lastMoveTo();

auto opSlice(size_t from, size_t to);

void opAssign(P rhs);

void reset();

void append(P rhs);

Point opIndex(size_t idx);

PathCmd cmd(size_t idx);

size_t length();

void* source();

bool inPlace();

}

Destructor

~this ~this(): Frees the memory used by the path.

Postblit

this(this) this(this): Undocumented in source.

Members

Functions

append void append(P rhs): append to the path
close Path close(): Close the current subpath. This draws a line back to the previous move command.
cmd PathCmd cmd(size_t idx): get the command at given index
cubicTo Path cubicTo(Scalar x1, Scalar y1, Scalar x2, Scalar y2, Scalar x3, Scalar y3): Add a cubic curve
inPlace bool inPlace(): Can be modified in place?
lastMoveTo Point lastMoveTo(): Get the coordinates of last move, IE. the start of current sub path
length size_t length(): the length of the path in points
lineTo Path lineTo(Scalar x, Scalar y): Line to x,y
lineTo Path lineTo(Point point): Line to point
moveTo Path moveTo(Scalar x, Scalar y): Move to x,y
moveTo Path moveTo(Point point): Move to point
opAssign void opAssign(P rhs): Copy rhs to this path, this handles self assignment, even if the rhs is a bunch of adaptors on top of the same path
opIndex Point opIndex(size_t idx): get the point at given index
opSlice auto opSlice(size_t from, size_t to): get a slice of the path, need to be careful as this doesnt do anything regarding aligning on full commands.
quadTo Path quadTo(Scalar x1, Scalar y1, Scalar x2, Scalar y2): Add a quadratic curve
reset void reset(): reset the path
source void* source(): Return the path source.
