Detailed Description

Describes a highlight quad of a text markup annotation.

The Quad is a closed path of 4 NormalizedPoints. Another set of 4 NormalizedPoints can be generated with transform(), e. g. to get highlighting coordinates on a rotated PageViewItem. Additionally, Quad stores some geometry related style attributes.

To enable correct rendering of the annotation, the points 0 and 1 must describe the bottom edge of the quad (relative to the text orientation).

Member Function Documentation

bool HighlightAnnotation::Quad::capEnd ( ) const

Returns whether a cap should be used at the end.

Definition at line 1928 of file annotations.cpp.

bool HighlightAnnotation::Quad::capStart ( ) const

Returns whether a cap should be used at the start.

Definition at line 1918 of file annotations.cpp.

double HighlightAnnotation::Quad::feather ( ) const

Returns the width of the drawing feather.

Definition at line 1938 of file annotations.cpp.

NormalizedPoint HighlightAnnotation::Quad::point ( int  index) const

Returns the normalized point at index.

index must be between 0 and 3.

Definition at line 1897 of file annotations.cpp.

void HighlightAnnotation::Quad::setCapEnd ( bool  value)

Sets whether a cap should be used at the end.

Definition at line 1923 of file annotations.cpp.

void HighlightAnnotation::Quad::setCapStart ( bool  value)

Sets whether a cap should be used at the start.

Definition at line 1913 of file annotations.cpp.

void HighlightAnnotation::Quad::setFeather ( double  width)

Sets the width of the drawing feather.

Definition at line 1933 of file annotations.cpp.

void HighlightAnnotation::Quad::setPoint ( const NormalizedPoint point,
int  index 
)

Sets the normalized point at index.

index must be between 0 and 3.

Definition at line 1889 of file annotations.cpp.

void HighlightAnnotation::Quad::transform ( const QTransform matrix)

Transforms the quad coordinates with the transformation defined by matrix.

The transformed coordinates will be accessible with transformedPoint(). The coordinates returned by point() are not affected.

NormalizedPoint HighlightAnnotation::Quad::transformedPoint ( int  index) const

Returns the transformed (e.g.

rotated) normalized point at index.

index must be between 0 and 3.
