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)
