Constructor Detail

Underline

public Underline(Color color,
                 float thickness,
                 float thicknessMul,
                 float yPosition,
                 float yPositionMul,
                 int lineCapStyle)

Creates an Underline. Both the thickness and vertical positioning under the text element's base line can be set to a fixed value, or a variable one depending on the element's font size. If you want a fixed-width thickness, set thicknessMul to 0; if you want a thickness solely dependent on the font size, set thickness to 0. Mutatis mutandis for the y-position.

Parameters:

color - the Color of the underline

thickness - a float defining the minimum thickness in points of the underline

thicknessMul - a float defining the font size dependent component of the thickness of the underline

yPosition - a float defining the default absolute vertical distance in points from the text's base line

yPositionMul - a float defining the font size dependent component of the vertical positioning of the underline

lineCapStyle - the way the underline finishes at its edges. PdfCanvasConstants.LineCapStyle

Underline

public Underline(Color color,
                 float opacity,
                 float thickness,
                 float thicknessMul,
                 float yPosition,
                 float yPositionMul,
                 int lineCapStyle)

Creates an Underline. Both the thickness and vertical positioning under the text element's base line can be set to a fixed value, or a variable one depending on the element's font size. If you want a fixed-width thickness, set thicknessMul to 0; if you want a thickness solely dependent on the font size, set thickness to 0. Mutatis mutandis for the y-position.

Parameters:

color - the Color of the underline

opacity - a float defining the opacity of the underline; a float between 0 and 1, where 1 stands for fully opaque color and 0 - for fully transparent

thickness - a float defining the minimum thickness in points of the underline

thicknessMul - a float defining the font size dependent component of the thickness of the underline

yPosition - a float defining the default absolute vertical distance in points from the text's base line

yPositionMul - a float defining the font size dependent component of the vertical positioning of the underline

lineCapStyle - the way the underline finishes at its edges. PdfCanvasConstants.LineCapStyle

Method Detail

getColor

public Color getColor()

Gets the color of the underline.

Returns:

a Color

getOpacity

public float getOpacity()

Gets the opacity of the underline color.

Returns:

a float between 0 and 1, where 1 stands for fully opaque color and 0 - for fully transparent

getThickness

public float getThickness(float fontSize)

Gets the total thickness of the underline (fixed + variable part).

Parameters:

fontSize - the font size for which to calculate the variable thickness

Returns:

the total thickness, as a float, in points

getYPosition

public float getYPosition(float fontSize)

Gets the vertical position of the underline (fixed + variable part).

Parameters:

fontSize - the font size for which to calculate the variable position

Returns:

the y-position, as a float, in points

getYPositionMul

public float getYPositionMul()

Gets the multiplier for the vertical positioning of the text underline.

Returns:

the Y-position multiplier, as a float

getLineCapStyle

public int getLineCapStyle()

Gets the PdfCanvasConstants.LineCapStyle of the text underline.

Returns:

the line cap style, as an int referring to the values of PdfCanvasConstants.LineCapStyle
