Methods that construct basic shapes within a container

Public Instance Methods

circle(r, cx=0, cy=0) click to toggle source

Draws a circle whose center is [cx, cy] and radius is r.

# File lib/rvg/embellishable.rb, line 243
def circle(r, cx=0, cy=0)
    circle = Circle.new(r, cx, cy)
    @content << circle
    circle
end
ellipse(rx, ry, cx=0, cy=0) click to toggle source

Draws an ellipse whose center is [cx, cy] and having a horizontal radius rx and vertical radius ry.

# File lib/rvg/embellishable.rb, line 251
def ellipse(rx, ry, cx=0, cy=0)
    ellipse = Ellipse.new(rx, ry, cx, cy)
    @content << ellipse
    ellipse
end
line(x1=0, y1=0, x2=0, y2=0) click to toggle source

Draws a line from [x1, y1] to [x2, y2].

# File lib/rvg/embellishable.rb, line 258
def line(x1=0, y1=0, x2=0, y2=0)
    line = Line.new(x1, y1, x2, y2)
    @content << line
    line
end
path(path) click to toggle source

Draws a path defined by an SVG path string or a PathData object.

# File lib/rvg/embellishable.rb, line 266
def path(path)
    path = Path.new(path)
    @content << path
    path
end
polygon(*points) click to toggle source

Draws a polygon. The arguments are [x, y] pairs that define the points that make up the polygon. At least two points must be specified. If the last point is not the same as the first, adds an additional point to close the polygon.

# File lib/rvg/embellishable.rb, line 293
def polygon(*points)
    polygon = Polygon.new(*points)
    @content << polygon
    polygon
end
polyline(*points) click to toggle source

Draws a polyline. The arguments are [x, y] pairs that define the points that make up the polyline. At least two points must be specified.

# File lib/rvg/embellishable.rb, line 302
def polyline(*points)
    polyline = Polyline.new(*points)
    @content << polyline
    polyline
end
rect(width, height, x=0, y=0) click to toggle source

Draws a rectangle whose upper-left corner is [x, y] and with the specified width and height. Unless otherwise specified the rectangle has square corners. Returns a Rectangle object.

Draw a rectangle with rounded corners by calling the round method on the Rectangle object. rx and ry are the corner radii in the x- and y-directions. For example:

canvas.rect(width, height, x, y).round(8, 6)

If ry is omitted it defaults to rx.

# File lib/rvg/embellishable.rb, line 282
def rect(width, height, x=0, y=0)
    rect = Rect.new(width, height, x, y)
    @content << rect
    rect
end
