9 # First all the build options off:
13 # Switch on the write code - this makes a minimalist encoder
17 # These 2 options are required if you need to read PBM (P1 or P4) files.
18 option WRITE_INVERT on
21 # You must choose fixed or floating point arithmetic:
22 # option FLOATING_POINT on
26 # You must chose the internal fixed point implementation or to
27 # use the system floating point. The latter is considerably
28 # smaller (by about 1kbyte on an x86 system):
29 # option FLOATING_ARITHMETIC on
31 option FLOATING_ARITHMETIC off
33 # Your program will probably need other options. The example
34 # program here, pnm2pngm, requires the following. Take a look
35 # at pnglibconf.h to find out the full set of what has to be
36 # enabled to make the following work.
