Method: HexaPDF::Content::Canvas#translate

Defined in:

lib/hexapdf/content/canvas.rb

#translate(x, y, &block) ⇒ Object

:call-seq:

canvas.translate(x, y)               => canvas
canvas.translate(x, y) { block }     => canvas

Translates the coordinate system coordinate system origin to the given x and y coordinates and returns self.

If invoked with a block, the translation of the coordinate system is only active during the block by saving and restoring the graphics state.

Examples:

#>pdf-center
canvas.stroke_color("hp-gray-light").
  rectangle(0, 0, 40, 20).stroke          # Rectangle from (0, 0) to (40, 20)
canvas.translate(50, 50) do               # Origin is now at (50, 50)
  canvas.stroke_color("hp-blue").
    rectangle(0, 0, 40, 20).stroke        # Actually (50, 50) to (90, 70)
end
