# 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 | |

option USER_LIMITS on |
