Function Documentation

stg_color_t stg_lookup_color (  const char *  name  ) 
 

Look up the color in the X11 database. (i.e. transform color name to color value). If the color is not found in the database, a bright red color (0xF00) will be returned instead.

void stg_pose_sum (  stg_pose_t *  result,
stg_pose_t *  p1,
stg_pose_t *  p2
) 
 

calculate the sum of [p1] and [p2], in [p1]'s coordinate system, and copy the result into result.

void stg_print_err (  const char *  err  ) 
 

Report an error, with a standard, friendly message header

void stg_print_geom (  stg_geom_t *  geom  ) 
 

Print human-readable geometry on stdout

void stg_print_gripper_config (  stg_gripper_config_t *  slc  ) 
 

Print human-readable version of the gripper config struct

void stg_print_laser_config (  stg_laser_config_t *  slc  ) 
 

Print human-readable version of the laser config struct

void stg_print_pose (  stg_pose_t *  pose  ) 
 

Print human-readable pose on stdout

void stg_print_velocity (  stg_velocity_t *  vel  ) 
 

Print human-readable velocity on stdout
