Enumeration Type Documentation

convolve_boundary_option

enum boost::gil::convolve_boundary_option

Boundary options for 1D correlations/convolutions

Enumerator
convolve_option_output_zero	do nothing to the output
convolve_option_extend_padded	set the output to zero
convolve_option_extend_zero	assume the source boundaries to be padded already
convolve_option_extend_constant	assume the source boundaries to be zero assume the source boundaries to be the boundary value
