Function Documentation

static void merge_sections (  MrLagSection *  left_section, MrLagSection *  right_section )  [static]

void mr_lag_section_add_segment (  MrLagSection *  section, void *  segment )

Add a segment to the section. Update the sum and mean

unsigned int mr_lag_section_area (  MrLagSection *  section  )

Return the sum of pixel in the section : return sum_height

void mr_lag_section_free (  void *  p  )

Destroys a section. Does not delete junctions and segments object in the vectors

unsigned int mr_lag_section_mean_Y (  MrLagSection *  section  )

Return the mean Y coordinate of the section. Used to define a horizontal line associated to this section.

MrLagSection* mr_lag_section_new (   )

Creates a new section

void mr_lag_section_remove (  MrLagSection *  section  )

update junction as the section does not exist any more

static void mr_lag_section_remove_junction_and_update (  MrLagSection *  section, MrLagJunction *  junction_to_remove, short int  left )  [static]

remove a junction in a section left = 1 : left junction else right junction And update the LAG structure by merging section if there is only one junction.
