# ----------------------------------------------------------------------------
# Makefile for PDFlib, Unix version
# (C) Thomas Merz 1997-98
# ----------------------------------------------------------------------------

VERSION	= 0.6

# ---------------------- Platform options -------------------------------
# One of the following platform defines must be set:
# -DWIN32	Windows 32 bit
#
# -DDOS		MS-DOS
#
# -DMAC		Apple Macintosh
#
# -DNeXT	NeXTSTEP
#
# -DPOSIX	Posix compatible system

# ---------------------- Configuration options -------------------------------
# Add the following defines for configuring several features:
# -DUSE_TIFF	use TIFF library for reading TIFF files (requires -DUSE_JPEG)
#		-DUSE_TIFF requires -ltiff and -ljpeg
#
# -DUSE_ZLIB	use zlib library for decompression (not yet implemented)
#		-DUSE_zlib requires -lgz (sometimes -lz)
#
# -DUSE_JPEG	use IJG JPEG library for decompressing non-baseline JPEGs
#		(currently not implemented)
#		This is only required for rare JPEGs, most are handled
#		internally in PDFlib. -DUSE_JPEG requires -ljpeg
#
# -DDEBUG	makes the PDF output more debug-friendly but may also
#       	obscure the bugs you're investigating (as predicted by 
#       	Heisenberg's law)

# TIFF and JPEG are not currently supported along with scripting
