NAME
lqr_carver_bias_set_energy_function_builtin - set a builtin energy function for a LqrCarver object
SYNOPSIS
#include <lqr.h> LqrRetVal lqr_carver_set_energy_function_builtin(LqrCarver* carver, LqrEnergyFuncBuiltinType ef_ind);
DESCRIPTION
The function lqr_carver_set_energy_function_builtin allows to pick a builtin energy function for the LqrCarver object pointed to by carver. The possible values for ef_ind are: LQR_EF_GRAD_XABS absolute value of the brightness gradient in the direction of the rescaling (this is the default) LQR_EF_GRAD_SUMABS sum of absolute values of the brightness gradients in both directions LQR_EF_GRAD_NORM norm of the brightness gradient LQR_EF_LUMA_GRAD_XABS absolute value of the luma gradient in the direction of the rescaling LQR_EF_LUMA_GRAD_SUMABS sum of absolute values of the luma gradients in both directions LQR_EF_LUMA_GRAD_NORM norm of the luma gradient LQR_EF_NULL null All of the above gradient functions have a radius of 1 pixel.
RETURN VALUE
The return value follows the Liquid Rescale library signalling system.
