| option SIMPLIFIED_WRITE on |

| # It isn't necessary to chose fixed or floating point for the APIs because the |
| # simplified API doesn't need fixed or floating point numbers. It is necessary |
| # to chose an internal math implementation. The default (because of 'everything |
| # = off') is fixed point - turn the floating point implementation on if you have |
| # hardware floating point or prefer your software floating point implementation. |
| option FLOATING_ARITHMETIC on |
| |
| # This is not strictly necessary, but without it the message strings in the API |
| # will not be filled in |
| option ERROR_TEXT on |
| |
| # Switching these options on enables the 'AFIRST' and 'BGR' formats - you don't |
| # need this if you don't use them, they just allow the in-memory layout to be |
| # changed to match common hardware formats. |
