# First all the build options off:

everything = off

# All that is required is some read code. This example switches
# on the sequential read code (see ../preader for a progressive
# read example).

option SEQUENTIAL_READ on

# You must choose fixed or floating point arithmetic:
# option FLOATING_POINT on

option FIXED_POINT on

# You must chose the internal fixed point implementation or to
# use the system floating point.  The latter is considerably
# smaller (by about 1kbyte on an x86 system):
# option FLOATING_ARITHMETIC on

option FLOATING_ARITHMETIC off

# Your program will probably need other options.  The example
# program here, pngm2pnm, requires the following.  Take a look
# at pnglibconf.h to find out the full set of what has to be
# enabled to make the following work.

option SETJMP on
option STDIO on
option READ_EXPAND on
option READ_STRIP_16_TO_8 on
