Detailed Description

Describes a type of stroke used to render a solid outline along a path.

A PathStrokeType object can be used directly to create the shape of an outline around a path, and is used by Graphics::strokePath to specify the type of stroke to draw.

Member Enumeration Documentation

◆ EndCapStyle

enum juce::PathStrokeType::EndCapStyle

The type shape to use for the ends of lines.

Enumerator
butt	Ends of lines are flat and don't extend beyond the end point.
square	Ends of lines are flat, but stick out beyond the end point for half the thickness of the stroke.
rounded	Ends of lines are rounded-off with a circular shape.

◆ JointStyle

enum juce::PathStrokeType::JointStyle

The type of shape to use for the corners between two adjacent line segments.

Enumerator

mitered

Indicates that corners should be drawn with sharp joints.

Note that for angles that curve back on themselves, drawing a mitre could require extending the point too far away from the path, so a mitre limit is imposed and any corners that exceed it are drawn as bevelled instead.

curved

Indicates that corners should be drawn as rounded-off.

beveled

Indicates that corners should be drawn with a line flattening their outside edge.

Constructor & Destructor Documentation

◆ PathStrokeType() [1/3]

juce::PathStrokeType::PathStrokeType ( float strokeThickness )

explicitnoexcept

Creates a stroke type with a given line-width, and default joint/end styles.

◆ PathStrokeType() [2/3]

juce::PathStrokeType::PathStrokeType	(	float	strokeThickness,
		JointStyle	jointStyle,
		EndCapStyle	endStyle = `butt`
	)

noexcept

Creates a stroke type.

Parameters

strokeThickness	the width of the line to use
jointStyle	the type of joints to use for corners
endStyle	the type of end-caps to use for the ends of open paths.

◆ PathStrokeType() [3/3]

juce::PathStrokeType::PathStrokeType ( const PathStrokeType & )

noexcept

Creates a copy of another stroke type.

◆ ~PathStrokeType()

juce::PathStrokeType::~PathStrokeType ( )

noexcept

Destructor.

Member Function Documentation

◆ createDashedStroke()

void juce::PathStrokeType::createDashedStroke	(	Path &	destPath,
		const Path &	sourcePath,
		const float *	dashLengths,
		int	numDashLengths,
		const AffineTransform &	transform = `AffineTransform()`,
		float	extraAccuracy = `1.0f`
	)		const

Applies this stroke type to a path, creating a dashed line.

This is similar to createStrokedPath, but uses the array passed in to break the stroke up into a series of dashes.

Parameters

destPath	the resultant stroked outline shape will be copied into this path. Note that it's ok for the source and destination Paths to be the same object, so you can easily turn a path into a stroked version of itself.
sourcePath	the path to use as the source
dashLengths	An array of alternating on/off lengths. E.g. { 2, 3, 4, 5 } will create a line of length 2, then skip a length of 3, then add a line of length 4, skip 5, and keep repeating this pattern.
numDashLengths	The number of lengths in the dashLengths array. This should really be an even number, otherwise the pattern will get out of step as it repeats.
transform	an optional transform to apply to the points from the source path as they are being used
extraAccuracy	if this is greater than 1.0, it will subdivide the path to a higher resolution, which improves the quality if you'll later want to enlarge the stroked path. So for example, if you're planning on drawing the stroke at 3x the size that you're creating it, you should set this to 3.

◆ createStrokedPath()

void juce::PathStrokeType::createStrokedPath	(	Path &	destPath,
		const Path &	sourcePath,
		const AffineTransform &	transform = `AffineTransform()`,
		float	extraAccuracy = `1.0f`
	)		const

Applies this stroke type to a path and returns the resultant stroke as another Path.

Parameters

destPath	the resultant stroked outline shape will be copied into this path. Note that it's ok for the source and destination Paths to be the same object, so you can easily turn a path into a stroked version of itself.
sourcePath	the path to use as the source
transform	an optional transform to apply to the points from the source path as they are being used
extraAccuracy	if this is greater than 1.0, it will subdivide the path to a higher resolution, which improves the quality if you'll later want to enlarge the stroked path. So for example, if you're planning on drawing the stroke at 3x the size that you're creating it, you should set this to 3.

◆ createStrokeWithArrowheads()

void juce::PathStrokeType::createStrokeWithArrowheads	(	Path &	destPath,
		const Path &	sourcePath,
		float	arrowheadStartWidth,
		float	arrowheadStartLength,
		float	arrowheadEndWidth,
		float	arrowheadEndLength,
		const AffineTransform &	transform = `AffineTransform()`,
		float	extraAccuracy = `1.0f`
	)		const

Applies this stroke type to a path and returns the resultant stroke as another Path.

Parameters

destPath	the resultant stroked outline shape will be copied into this path. Note that it's ok for the source and destination Paths to be the same object, so you can easily turn a path into a stroked version of itself.
sourcePath	the path to use as the source
arrowheadStartWidth	the width of the arrowhead at the start of the path
arrowheadStartLength	the length of the arrowhead at the start of the path
arrowheadEndWidth	the width of the arrowhead at the end of the path
arrowheadEndLength	the length of the arrowhead at the end of the path
transform	an optional transform to apply to the points from the source path as they are being used
extraAccuracy	if this is greater than 1.0, it will subdivide the path to a higher resolution, which improves the quality if you'll later want to enlarge the stroked path. So for example, if you're planning on drawing the stroke at 3x the size that you're creating it, you should set this to 3.
