PreProcessor Defines:
use_int32:
When enabled 32bit integers are used instead of 64bit integers. This improves clipping performance by about 20-30% but coordinate values are limited to the range ± 46340. (Disabled by default)
use_xyz:
Adds a 'Z' member to IntPoint with only a minor cost to perfomance. For more details see Clipper's ZFillFunction property. (Disabled by default)
use_lines:
Enables open path (line) clipping. If line clipping is disabled, there's generally a very small (ie ~5%) improvement in performance. (Enabled by default)
use_deprecated:
Enables code developed with versions of Clipper prior to version 6 to compile without changes.
This exposes compatability code that will be removed in a future update. (Enabled by default)
