% PStill can 'draw' graphics on the output pages, script controlled
% You can activate a script in the GUI under Options->N-UP Output Options
% Or use -m pagecontrol=scriptname.sl on the command line
%
% This script gives an example how to paint with white rectangles on the
% page to cover elements like page numbers or logos you don't want to see 
% anymore visually.
%
% ps_do_showpage(int pagenum) is called for each processed page
% The variable "pagenum" is set to the current page number during processing

define ps_do_showpage(pagenum) {

	% startGFX must be called before the first commands are used

	startGFX();

	% set the current color in RGB (values 0.0. to 1.0), To white

	setRGBColor (1.0, 1.0, 1.0);

	% EDIT THE NEXT LINE YOURSELF - it paints a rectangle in the 
	% current color as defined above
	% You need to find out where your page number on the input
	% pages is located. An easy way is to set the color
	% to red (setRGBColor(1.0,0,0);) and set the X,Y and W/H size
	% below by trial and error. Zero is the lower left corner
	% values are in 1/72 inch pts.

	drawRect(280,10,50,30);

	% remember: you can also paint different on odd pages
	% and even pages. Thats just a simple check
	%
	% if (pagenum mod 2 == 0) {
	%	drawRect(....);
 	% } else {
	% 	drawRect(....);
	% }	

	% The next call ends the page drawing
	% it MUST be called before exiting this function

	endGFX();
