VectorGraphics

Overview

VectorGraphics is a class in Aspose.PDF FOSS for TypeScript.

A buffered builder for vector content: every path constructor, paint operator, graphics-state setting and marked-content bracket, accumulated in memory as operator text.

This class declares 41 methods for VectorGraphics objects in TypeScript programs. Available methods include: BeginArtifact, BeginLayer, BeginMarkedContent, EndLayer, EndMarkedContent, arc, circle, close, curveTo, drawLine, drawRect, ellipse, and 25 additional methods. All public members are accessible to any TypeScript application after installing the Aspose.PDF FOSS for TypeScript package. Properties: ctm, liveMask, ref.

Methods

Signature	Description
`setLineWidth(w: number)` → `this`	Sets the line width value.
`setStrokeColor(rgb: [number, number, number])` → `this`	Sets the stroke color value.
`setFillColor(rgb: [number, number, number])` → `this`	Sets the fill color value.
`setFillGradient(g: Gradient)` → `this`	Fill subsequent paths with an axial or radial gradient.
`setStrokeGradient(g: Gradient)` → `this`	Stroke subsequent paths with an axial or radial gradient.
`setFillPattern(pattern: ColoredTilingPattern)` → `this`	Fill subsequent paths with `pattern`, a tiling pattern from {@link Document.NewTilingPattern}.
`setFillPattern(pattern: UncoloredTilingPattern, color: [number, number, number])` → `this`	Sets the fill pattern value.
`setFillPattern(pattern: TilingPattern, color: [number, number, number])` → `this`	Sets the fill pattern value.
`setStrokePattern(pattern: ColoredTilingPattern)` → `this`	Stroke subsequent paths with `pattern`.
`setStrokePattern(pattern: UncoloredTilingPattern, color: [number, number, number])` → `this`	Sets the stroke pattern value.
`setStrokePattern(pattern: TilingPattern, color: [number, number, number])` → `this`	Sets the stroke pattern value.
`setLineCap(cap: 0 \| 1 \| 2)` → `this`	Sets the line cap value.
`setLineJoin(join: 0 \| 1 \| 2)` → `this`	Sets the line join value.
`setMiterLimit(limit: number)` → `this`	Miter limit: the ratio at which a miter join (`setLineJoin(0)`) is cut off into a bevel.
`setDash(pattern: number[], phase)` → `this`	Sets the dash value.
`setOpacity(alpha: number)` → `this`	Sets the opacity value.
`save()` → `this`	Calls save on this VectorGraphics instance.
`restore()` → `this`	Calls restore on this VectorGraphics instance.
`transform(a: number, b: number, c: number, d: number, e: number, f: number)` → `this`	Calls transform(a, b, c, d, e, f) on this VectorGraphics instance.
`BeginMarkedContent(tag: string, mcid: number)` → `this`	Begin a marked-content sequence carrying an /MCID.
`BeginArtifact()` → `this`	Begin an artifact sequence: `/Artifact BMC`, marking the following ops as content that belongs to no structure element.
`EndMarkedContent()` → `this`	End the most recent marked-content sequence.
`BeginLayer(layer: Layer)` → `this`	Begin an optional-content sequence: `/OC /<key> BDC`, tagging following ops into `layer`.
`EndLayer()` → `this`	End the most recent {@link BeginLayer} sequence.
`moveTo(x: number, y: number)` → `this`	Calls moveTo(x, y) on this VectorGraphics instance.
`lineTo(x: number, y: number)` → `this`	Calls lineTo(x, y) on this VectorGraphics instance.
`curveTo(x1: number, y1: number, x2: number, y2: number, x3: number, y3: number)` → `this`	Calls curveTo(x1, y1, x2, y2, x3, y3) on this VectorGraphics instance.
`rect(x: number, y: number, w: number, h: number)` → `this`	Calls rect(x, y, w, h) on this VectorGraphics instance.
`close()` → `this`	Calls close on this VectorGraphics instance.
`drawLine(x1: number, y1: number, x2: number, y2: number)` → `this`	Calls drawLine(x1, y1, x2, y2) on this VectorGraphics instance.
`drawRect(x: number, y: number, w: number, h: number)` → `this`	Calls drawRect(x, y, w, h) on this VectorGraphics instance.
`circle(cx: number, cy: number, r: number)` → `this`	Calls circle(cx, cy, r) on this VectorGraphics instance.
`polyline(points: [number, number][])` → `this`	An open polyline through `points` (at least two `[x, y]` pairs): a moveTo followed by a lineTo each.
`polygon(points: [number, number][])` → `this`	A closed polygon through `points`: {@link polyline} plus a closing `h`, so a fill has a well-defined boundary and a stroke joins the last edge to the first rather than capping it.
`roundedRect(x: number, y: number, w: number, h: number, r: number)` → `this`	A rectangle with quarter-circle corners of radius `r`, clamped to half the shorter side (so an over-large radius gives a stadium, never a self-crossing path).
`arc(cx: number, cy: number, r: number, startAngle: number, endAngle: number)` → `this`	A circular arc of radius `r` about (`cx`, `cy`), from `startAngle` to `endAngle` in radians (0 = +x axis, increasing counter-clockwise, as in Canvas 2D).
`ellipse(cx: number, cy: number, rx: number, ry: number)` → `this`	Calls ellipse(cx, cy, rx, ry) on this VectorGraphics instance.
`stroke()` → `this`	Calls stroke on this VectorGraphics instance.
`fill()` → `this`	Calls fill on this VectorGraphics instance.
`fillEvenOdd()` → `this`	Calls fillEvenOdd on this VectorGraphics instance.
`fillStroke()` → `this`	Calls fillStroke on this VectorGraphics instance.
