Constructor Details

#initialize(width = 0, height = 0, x = 0, y = 0) {|_self| ... } ⇒ Pattern

Create a pattern that can be used with the :fill or :stroke styles. The width and height arguments define the viewport. The pattern will be repeated at x+m*width and y+n*height offsets.

Define the pattern in the block. The pattern can be composed of shapes (rectangle, circles, etc.), text, raster images and container objects. You can include graphic objects by referring to them with #use.

Yields:

• (_self)

Yield Parameters:

• _self (Magick::RVG::Pattern) —

  the object that the method was called on

# File 'lib/rvg/paint.rb', line 33

def initialize(width = 0, height = 0, x = 0, y = 0)
  super()
  @width, @height, @x, @y = Magick::RVG.convert_to_float(width, height, x, y)
  @content = Content.new
  yield(self) if block_given?
end

#height ⇒ Object (readonly)

Return upper-left corner, width, height of viewport in user coordinates. Usually these are the values specified when the Pattern object is created, but they can be changed by a call to the viewbox method.

def height
  @height
end

#width ⇒ Object (readonly)

Return upper-left corner, width, height of viewport in user coordinates. Usually these are the values specified when the Pattern object is created, but they can be changed by a call to the viewbox method.

def width

end

#x ⇒ Object (readonly)
