/*
# tile - resize a postscript image to print on larger media and/or multiple sheets
#
# This program scales a PostScript page to a given size (a poster).
# The output can be tiled on multiple sheets, and output
# media size can be chosen independently.
# Each tile (sheet) of a will bear cropmarks and slightly overlapping
# image for easier poster assembly.
# In principle it requires the input file to adhere to 'eps'
# (encapsulated postscript) conventions but it will work for many
# 'normal' postscript files as well.
#
# Compile this program with:
# cc -O -o tile tile.c -lm
# or something alike.
#
# Maybe you want to change the `DefaultMedia' and `DefaultImage'
# settings in the few lines below, to reflect your local situation.
# Names can to be chosen from the `mediatable' further down.
#
# The `Gv_gs_orientbug 1' disables a feature of this program to
# ask for landscape previewing of rotated images.
# Our currently installed combination of ghostview 1.5 with ghostscript 3.33
# cannot properly do a landscape viewing of the `poster' output.
# The problem does not exist in combination with an older ghostscript 2.x,
# and has the attention of the ghostview authors.
# (The problem is in the evaluation of the `setpagedevice' call.)
# If you have a different previewing environment,
# you might want to set `Gv_gs_orientbug 0'
#
# Tile now adds a coverpage, and takes the t and h options.
# I (joost) have yet to make this optional, and update the man page.
#
# Tile has now support for language files
# (tile.<2 letter language code>.yml, "tile.en.yml")
