BLApproximationOptions Struct Reference
Options used to describe how geometry is approximated.
This struct cannot be simply zeroed and then passed to functions that accept approximation options. Use blDefaultApproximationOptions to setup defaults and then alter values you want to change.
Example of using BLApproximationOptions:
// Initialize with defaults first.
// Override values you want to change.
approx.simplifyTolerance = 0.02;
// ... now safely use approximation options in your code ...

uint8_t BLApproximationOptions::flattenMode[¶]
Specifies how curves are flattened, see BLFlattenMode.
uint8_t BLApproximationOptions::offsetMode[¶]
Specifies how curves are offsetted (used by stroking), see BLOffsetMode.
uint8_t BLApproximationOptions::reservedFlags[6][¶]
Reserved for future use, must be zero.
double BLApproximationOptions::flattenTolerance[¶]
Tolerance used to flatten curves.
double BLApproximationOptions::simplifyTolerance[¶]
Tolerance used to approximate cubic curves with quadratic curves.
double BLApproximationOptions::offsetParameter[¶]
Curve offsetting parameter, exact meaning depends on offsetMode.
