Rendering the Canvas as PostScript

To get a copy of the Canvas as PostScript, use the postscript method. It will either return the PostScript output or, if the -file option is specified, put it in a file: 

$postscript = $canvas->postscript( ); $canvas->postscript(-file => "ps.out");

The following options allow you to control the output of the PostScript:

  • -colormap => \@array
  • Specifies that each element in @array must be a valid PostScript command for setting color values (e.g., "1.0 1.0 0.0 setrgbcolor").
  • -colormode => "color" | "gray" | "mono"
  • Creates the PostScript in full color, grayscale ("gray"), or black and white ("mono").
  • -file => filename
  • Specifies the file in which to put the PostScript output.
  • -fontmap => \@array
  • Each element in @array is a two-element array that contains a font name and a point size. The font name should be a complete font name so Tk will parse it correctly (e.g., "-*-Helvetica-Bold-O-Normal--*-140-*").
  • -height => size
  • Sets the height of the area to print. The default height is the Canvas height.
  • -pageanchor => "n" | "e" | "s" | "w" | "center"
  • Indicates where the page should be placed over the positioning point specified by the -pagex and -pagey options.
  • -pageheight => height
  • Sets the height of the printed page. The Canvas image will be scaled to fit. height is any valid screen distance.
  • -pagewidth => width
  • Sets the width of the printed page. The Canvas image will be scaled to fit.
  • -pagex => x
  • Sets the coordinate for the x positioning point. Can be any valid screen distance.
  • -pagey => y
  • Sets the coordinate for the y positioning point. Can be any valid screen distance.
  • -rotate => 0 | 1
  • If 1, the page is rotated into a landscape orientation. Default is 0, which is portrait orientation.
  • -width => size
  • Sets the width of the Canvas area to be printed. Defaults to the width of the Canvas.
  • -x => x
  • Sets the left edge of the area to be printed (in Canvas coordinates). Default is the left edge of the window.
  • -y => y
  • Sets the top edge of the area to be printed (in Canvas coordinates). Default is the left edge of the window.
