◆ SetLeading()

void Opait.Pdf.PdfPainter.SetLeading ( double leading )

Set the text leading: the vertical distance between the baselines of adjacent lines of text. (TL)

Parameters

◆ SetLineCap()

void Opait.Pdf.PdfPainter.SetLineCap ( PdfLineCap cap )

Set the line cap style in the graphics state.

Parameters

◆ SetLineDash() [1/2]

void Opait.Pdf.PdfPainter.SetLineDash	(	int	dash,
		int	gap = `0`,
		int	phase = `0`
	)

Sets dash and gap pattern (d).

The line dash pattern controls the pattern of dashes and gaps used to stroke paths. It is specified by a dash array and a dash phase. The dash array’s elements are numbers that specify the lengths of alternating dashes and gaps; the numbers must be nonnegative and not all zero. The dash phase specifies the distance into the dash pattern at which to start the dash.The elements of both the dash array and the dash phase are expressed in user space units.

Parameters

dash	The dash length.
gap	The gap length, 0 means same as the dash length.
phase	The dash phase.

◆ SetLineDash() [2/2]

void Opait.Pdf.PdfPainter.SetLineDash	(	string	pattern,
		int	phase = `0`
	)

Sets user defined array of dashes and gaps. The pattern must be enclosed in square brackets (e.g. '[3 1 1 1]' for a dash-dot pattern).

Parameters

pattern	The dash gap pattern.
phase	The dash phase.

◆ SetLineJoin()

void Opait.Pdf.PdfPainter.SetLineJoin ( PdfLineJoin join )

Set the line join style in the graphics state.

Parameters

join	The PdfLineJoin style to set.

void Opait.Pdf.PdfPainter.SetStrokeColor	(	double	r,
		double	g,
		double	b
	)

Set RGB color for stroking operations (RG)

Parameters

r	The red component in the range [0,1]
g	The Green component in the range [0,1]
b	The Blue component in the range [0,1]

◆ SetStrokeGray()

void Opait.Pdf.PdfPainter.SetStrokeGray ( double g )

Set gray level for stroking operations (G).

Parameters

g	The gray level between 0 and 1.

◆ SetTextMatrix()

void Opait.Pdf.PdfPainter.SetTextMatrix ( PdfMatrix m )

Sets the text matrix and the text line matrix. (Tm)

Parameters

m	The text matrix to set.

◆ SetTextPos()

void Opait.Pdf.PdfPainter.SetTextPos	(	double	x,
		double	y
	)

Sets the absolute position for the next text output.

Parameters

x	The x-coordinate.
y	The y-coordinate.

◆ SetTextRise()

void Opait.Pdf.PdfPainter.SetTextRise ( double rise )
