This script extracts macros #defines from those OpenCV headers that can't be
|
||
|
|
directly parsed by current SWIG versions and must be pre-filtered by
|
||
|
|
the C preprocessor (that erases all #defines). Type information is missing in the
|
||
|
|
macros, so C code can't be regenerated. Instead, try to convert C to Python code.
|
||
|
|
C macros too complicated to represent in python using regexes are listed in EXCLUDE
