Constructor & Destructor Documentation

◆ Pen() [1/2]

pcl::Pen::Pen ( RGBA  color = 0xff000000,
float  width = 0,
style  s = PenStyle::Solid,
cap  c = PenCap::Square,
join  j = PenJoin::Miter 
)

Constructs a Pen object with the specified color, width in pixels, and drawing, cap and join styles.

◆ Pen() [2/2]

pcl::Pen::Pen ( const Pen &  p)
inline

Copy constructor. This object will reference the same server-side pen as the specified instance p.

Definition at line 192 of file Pen.h.

◆ ~Pen()

pcl::Pen::~Pen ( )
inlineoverride

Destroys a Pen object. If this object references an existing pen in the PixInsight core application, its reference count is decremented. If it becomes unreferenced, it will be garbage-collected.

Definition at line 201 of file Pen.h.

Member Function Documentation

◆ Brush()

pcl::Brush pcl::Pen::Brush ( ) const

Returns the current pen brush.

See also
SetBrush()

◆ Cap()

cap pcl::Pen::Cap ( ) const

Returns the current pen cap style.

See also
SetCap()

◆ Color()

RGBA pcl::Pen::Color ( ) const

Returns the pen color as a 32-bit AARRGGBB pixel color value.

See also
SetColor()

◆ GetBrush()

pcl::Brush pcl::Pen::GetBrush ( ) const
inline

Returns the current pen brush.

Deprecated:
Use Pen::Brush() in newly produced code.
See also
SetBrush()

Definition at line 337 of file Pen.h.

◆ IsEmpty()

bool pcl::Pen::IsEmpty ( ) const
inline

Returns true iff this pen draws no strokes, i.e. if the current pen drawing style is PenStyle::Empty.

See also
IsSolid(), Style()

Definition at line 284 of file Pen.h.

◆ IsSolid()

bool pcl::Pen::IsSolid ( ) const
inline

Returns true iff this pen draws solid strokes, i.e. if the current pen drawing style is PenStyle::Solid.

See also
IsEmpty(), Style()

Definition at line 273 of file Pen.h.

◆ Join()

join pcl::Pen::Join ( ) const

Returns the current pen join style.

See also
SetJoin()

◆ Null()

static Pen& pcl::Pen::Null ( )
static

Returns a reference to a null pen. A null Pen object does not correspond to an existing pen object in the PixInsight core application.

◆ operator=()

Pen& pcl::Pen::operator= ( const Pen &  p)
inline

Assignment operator. Returns a reference to this object.

Makes this object reference the same server-side pen as the specified instance p. If the previous pen becomes unreferenced, it will be garbage-collected by the PixInsight core application.

Definition at line 212 of file Pen.h.

◆ SetBrush()

void pcl::Pen::SetBrush ( const pcl::Brush &  brush)

Sets the current pen brush

See also
Brush()

◆ SetCap()

void pcl::Pen::SetCap ( cap  c)

Sets the current pen cap style.

See also
Cap()

◆ SetColor()

void pcl::Pen::SetColor ( RGBA  color)

Sets the pen color as a 32-bit AARRGGBB pixel color value.

See also
Color()

◆ SetJoin()

void pcl::Pen::SetJoin ( join  j)

Sets the current pen join style.

See also
Join()

◆ SetStyle()

void pcl::Pen::SetStyle ( style  )

Sets the pen drawing style.

See also
Style(), IsSolid(), IsEmpty()

◆ SetWidth()

void pcl::Pen::SetWidth ( float  w)

Sets the pen width in pixels.

A zero width means that this is a cosmetic pen. Cosmetic pens always draw one-pixel strokes, regardless of the transformation applied to the graphics context where they are applied.

See also
Width()

◆ Style()

style pcl::Pen::Style ( ) const

Returns the current pen drawing style.

See also
SetStyle(), IsSolid(), IsEmpty()

◆ Width()

float pcl::Pen::Width ( ) const

Returns the pen width in pixels.

A zero width means that this is a cosmetic pen. Cosmetic pens always draw one-pixel strokes, regardless of the transformation applied to the graphics context where they are applied.
