% ------ Usage ----------------------------------------------------------------

% To use this file either send it to a postscript printer, or use your 
% favourite postscript interpreter to visualize and print it.

% You can customize the result by changing the values in the Settings 
% section below (see the comments for details)

% ------ sizes ----------------------------------------------------------------
% This will allow you to give measurements in inches or millimiters
% do not change
/inch {72 mul} def
/mm {0.03937 inch mul} def

% ------ Settings -------------------------------------------------------------

% ------ Basic settings

/HexSide {{ hex_side }} def              % lenght of hexagon side (or "radius")

/LineSize {{ thin_line_size }} def              % lines width
/LineColo {{ thin_line_color }} def  % rgb triplet of line color
/FillColo {{ fill_color }} def  % rgb triplet of hexagon color
/BackColo {{ background_color }} def  % rgb triplet of background color

% page size: if you change this, you should change the BoundingBox
% in line 4 accordingly (you CAN'T use mm or inch over there)
/PageWidth  {{ page_width }} def
/PageHeight {{ page_height }} def

% white margins
/BorderTop {{ margin_top }} def
/BorderBottom {{ margin_bottom }} def
/BorderLeft {{ margin_left }} def
/BorderRight {{ margin_right }} def

% ------ Advanced settings

% spacing between consecutive hexes (hor and vert)
/HexSpaceX {{ x_spacing }} def
/HexSpaceY {{ y_spacing }} def
{% if uniform_spacing %}
% uniform spacing, overrides the setting for y spacing
/HexSpaceY HexSpaceX 3 sqrt 0.5 mul mul def
{% endif %}

% translation of the starting point of the pattern
/PattTrasX {{ x_trasl }} def
/PattTrasY {{ y_trasl }} def

% ------ Behaviour 

% Whether to print a line around the margins (1) or not (0)
/WillPrintBorder {{ 1 if border else 0 }} def

% From here on you shouldn't worry about changing or configuring anything
% ------ Variables ------------------------------------------------------------

% Spacing between hexagons
/HexSpacingX HexSide 3 sqrt mul HexSpaceX add def
/RowSpacingY HexSide 1.5 mul HexSpaceY add def
/ColSpacingX HexSide 3 sqrt 0.5 mul mul HexSpaceX 2 div add def

% x y movements to get oblique sides
/HexSideX HexSide 3 sqrt 0.5 mul mul def
/HexSideY HexSide 2 div def

% number of hexagons in a row and of rows in a page
/HexRowNum PageWidth HexSpacingX div 2 add def
/HexColNum PageHeight RowSpacingY div 2 add def

% starting hexagon number in a row and row number in a page
/HexRowSta PattTrasX HexSpacingX div cvi neg 1 sub def
/HexColSta PattTrasY RowSpacingY div cvi neg 1 sub def

% ending hexagon number in a row and row number in a page
/HexRowEnd HexRowSta HexRowNum add def
/HexColEnd HexColSta HexColNum add def
