Methods

applyShader(PdfShading shader) → void

Apply a shader

bezierArc(double x1, double y1, double rx, double ry, double x2, double y2, {bool large = false, bool sweep = false, double phi = 0.0}) → void

Draws an elliptical arc from (x1, y1) to (x2, y2). The size and orientation of the ellipse are defined by two radii (rx, ry) The center (cx, cy) of the ellipse is calculated automatically to satisfy the constraints imposed by the other parameters. large and sweep flags contribute to the automatic calculations and help determine how the arc is drawn.

clipPath({bool evenOdd = false, bool end = true}) → void

Create a clipping surface from the previously defined shape, to prevent any further drawing outside

closePath() → void

Close the path with a line

curveTo(double x1, double y1, double x2, double y2, double x3, double y3) → void

Draw a cubic bézier curve from the current point to (x3,y3) using (x1,y1) as the control point at the beginning of the curve and (x2,y2) as the control point at the end of the curve.

drawBox(PdfRect box) → void

Draws a Rectangle

drawEllipse(double x, double y, double r1, double r2, {bool clockwise = true}) → void

Draws an ellipse

drawImage(PdfImage img, double x, double y, [double? w, double? h]) → void

Draws an image onto the page.

drawLine(double x1, double y1, double x2, double y2) → void

Draws a line between two coordinates.

drawRect(double x, double y, double w, double h) → void

Draws a Rectangle

drawRRect(double x, double y, double w, double h, double rv, double rh) → void

Draws a Rounded Rectangle

drawShape(String d) → void

Draw an SVG path

drawString(PdfFont font, double size, String s, double x, double y, {double? charSpace, double? wordSpace, double? scale, PdfTextRenderingMode mode = PdfTextRenderingMode.fill, double? rise}) → void

This draws a string.

fillAndStrokePath({bool evenOdd = false, bool close = false}) → void

Draw a surface on the previously defined shape and then draw the contour set evenOdd to false to use the nonzero winding number rule to determine the region to fill and to true to use the even-odd rule to determine the region to fill

fillPath({bool evenOdd = false}) → void

Draw a surface on the previously defined shape set evenOdd to false to use the nonzero winding number rule to determine the region to fill and to true to use the even-odd rule to determine the region to fill

getTransform() → Matrix4

Get the transformation Matrix

lineTo(double x, double y) → void

This adds a line segment to the current path

markContentBegin(PdfName tag) → void

markContentEnd() → void

moveTo(double x, double y) → void

This moves the current drawing point.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

reset() → void

restoreContext() → void

This releases any resources used by this Graphics object. You must use this method once finished with it.

saveContext() → void

Save the graphic context

setColor(PdfColor? color) → void

Sets the color for drawing

setFillColor(PdfColor? color) → void

Sets the fill color for drawing

setFillPattern(PdfPattern pattern) → void

Sets the fill pattern for drawing

setFont(PdfFont font, double size, {double? charSpace, double? wordSpace, double? scale, PdfTextRenderingMode mode = PdfTextRenderingMode.fill, double? rise}) → void

Set the current font and size

setGraphicState(PdfGraphicState state) → void

Set the graphic state for drawing

setLineCap(PdfLineCap cap) → void

Set line starting and ending cap type

setLineDashPattern([List<num> array = const <num>[], int phase = 0]) → void

The dash array shall be cycled through, adding up the lengths of dashes and gaps. When the accumulated length equals the value specified by the dash phase

setLineJoin(PdfLineJoin join) → void

Set line join type

setLineWidth(double width) → void
