module Magick::RVG::StructureConstructors

Methods that construct container objects within a container

Public Instance Methods

g(&block) click to toggle source

Defines a group.

This method constructs a new Group container object. The styles and transforms specified on this object will be used by objects contained within, unless overridden by an inner container or the contained object itself. Define grouped elements by calling RVG::Embellishable methods within the associated block.

# File lib/rvg/embellishable.rb, line 352
def g(&block)
  group = Group.new(&block)
  @content << group
  group
end
rvg(cols, rows, x = 0, y = 0, &block) click to toggle source

Establishes a new viewport. [x, y] is the coordinate of the upper-left corner within the containing viewport. This is a container method. Styles and transforms specified on this object will be used by objects contained within, unless overridden by an inner container or the contained object itself.

# File lib/rvg/embellishable.rb, line 329
def rvg(cols, rows, x = 0, y = 0, &block)
  rvg = Magick::RVG.new(cols, rows, &block)
  begin
    x = Float(x)
    y = Float(y)
  rescue ArgumentError
    args = [cols, rows, x, y]
    raise ArgumentError, "at least one argument is not convertable to Float (got #{args.map(&:class).join(', ')})"
  end
  rvg.corner(x, y)
  @content << rvg
  rvg
