PdfBezierCurveElement Class


PdfBezierCurveElement Class

Represents a cubic Bezier curve drawn in a pdf document. A Bezier curve is specified by 4 points: a start point, two control points, and an end point. The curve is stroke-only (no fill) using ForeColor (black by default) and LineStyle.

The PdfBezierCurveElement type exposes the following members.

Constructors

	Name	Description
	PdfBezierCurveElement(PointF, PointF, PointF, PointF)	Convenience overload — constructs a Bezier curve element from four PointF values.
	PdfBezierCurveElement(Single, Single, Single, Single, Single, Single, Single, Single)	Constructs a Bezier curve element.

Properties

	Name	Description
	ActualText	Gets or sets the exact text represented by this element (the structure element's /ActualText entry), used when the drawn glyphs do not map to readable text. (Inherited from PdfPageElement)
	AlternateText	Gets or sets the alternate text describing this element for assistive technology (the structure element's /Alt entry). Required on figures for PDF/UA conformance. (Inherited from PdfPageElement)
	Artifact	Gets or sets a value indicating whether this element is an artifact — decorative or layout content that carries no meaning and is excluded from the logical structure (backgrounds, rules, running headers). Takes precedence over TagType. (Inherited from PdfPageElement)
	BackColor	Gets or sets the background fill color. (Inherited from PdfElement)
	Blending	Gets or sets the blending mode. (Inherited from PdfElement)
	ColorSpace	Gets or sets the color space for the pdf element rendering. (Inherited from PdfElement)
	ForeColor	Gets or sets the foreground color used for drawing outlines and text. (Inherited from PdfElement)
	Gradient	Gets or sets the gradient fill. When set, overrides BackColor for fills. (Inherited from PdfElement)
	LineStyle	Gets or sets the line style for outline drawing. (Inherited from PdfElement)
	Rotated	Gets a value indicating whether a rotation has been applied. (Inherited from PdfElement)
	Scaled	Gets a value indicating whether a scale has been applied. (Inherited from PdfElement)
	Skewed	Gets a value indicating whether a skew has been applied. (Inherited from PdfElement)
	TagType	Gets or sets the structure type used to tag this element in a tagged (accessible) document. Ignored unless the document's tagged mode (PdfDocument.Tagged) is enabled. Null (default) leaves the element untagged unless Artifact is set. (Inherited from PdfPageElement)
	Translated	Gets a value indicating whether a translation has been applied. (Inherited from PdfElement)
	Transparency	Gets or sets the transparency level (0 = completely transparent, 100 = completely opaque). (Inherited from PdfElement)
	X1	The start point X coordinate.
	X2	The first control point X coordinate.
	X3	The second control point X coordinate.
	X4	The end point X coordinate.
	Y1	The start point Y coordinate.
	Y2	The first control point Y coordinate.
	Y3	The second control point Y coordinate.
	Y4	The end point Y coordinate.

Example

Copy

PdfDocument document = new PdfDocument();
PdfPage page = document.AddPage();
PdfBezierCurveElement curve =
    new PdfBezierCurveElement(20, 100, 80, 20, 160, 180, 220, 100);
curve.ForeColor = new PdfColor(0, 120, 215);
page.Add(curve);
document.Save("out.pdf");
document.Close();

Dim document As New PdfDocument()
Dim page As PdfPage = document.AddPage()
Dim curve As New PdfBezierCurveElement(20, 100, 80, 20, 160, 180, 220, 100)
curve.ForeColor = New PdfColor(0, 120, 215)
page.Add(curve)
document.Save("out.pdf")
document.Close()
