# First all the build options off:

everything = off

# Just switch on the progressive read code

option PROGRESSIVE_READ on

# You may choose fixed or floating point APIs:
# 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, rpng2-x, 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
