Public Instance methods

circle(r, cx=0, cy=0)

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

     # File lib/rvg/embellishable.rb, line 264
264:             def circle(r, cx=0, cy=0)
265:                 circle = Circle.new(r, cx, cy)

267:                 return circle
268:             end
ellipse(rx, ry, cx=0, cy=0)

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

     # File lib/rvg/embellishable.rb, line 272
272:             def ellipse(rx, ry, cx=0, cy=0)
273:                 ellipse = Ellipse.new(rx, ry, cx, cy)
274:                 @content << ellipse
275:                 return ellipse
276:             end
line(x1=0, y1=0, x2=0, y2=0)

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

     # File lib/rvg/embellishable.rb, line 279
279:             def line(x1=0, y1=0, x2=0, y2=0)
280:                 line = Line.new(x1, y1, x2, y2)
281:                 @content << line
282:                 return line
283:             end
path(path)

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

     # File lib/rvg/embellishable.rb, line 287
287:             def path(path)
288:                 path = Path.new(path)
289:                 @content << path
290:                 return path
291:             end
polygon(*points)

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 314
314:             def polygon(*points)
315:                 polygon = Polygon.new(*points)
316:                 @content << polygon
317:                 return polygon
318:             end
polyline(*points)

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.

[Source]

     # File lib/rvg/embellishable.rb, line 323
323:             def polyline(*points)
324:                 polyline = Polyline.new(*points)
325:                 @content << polyline
326:                 return polyline
327:             end
rect(width, height, x=0, y=0)

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.

303:             def rect(width, height, x=0, y=0)
304:                 rect = Rect.new(width, height, x, y)
305:                 @content << rect
306:                 return rect
307:             end
