image_map_new
This function creates a new ImageMap and returns a handle to it. The contents of the map are undefined.
image_map_free map
Free the memory allocated for ImageMap map.
image_map_copy src dest
Copies the lookup table entries from src into dest.
image_map_init map values
Initializes the entries of map using values.
The parameter values must be a list of 256 integers in the range 0..255.
image_map_init_identity map
Initializes map to the identity function (i.e., the value of entry i is i).
image_map_init_inverse map
Initializes map to the complement function (i.e., the value of entry i is 255-i)
image_map_init_histo_equal image map
Sets the values of map so that they will perform histogram equalization on image.
image_map_compose map1 map2 dest
Compute the composition of map1 and map2 and store it in dest. Applying dest to a ByteImage is equivalent to applying map1 and then applying map2 to that image.
image_map_apply map src dest
Applies map to src and stores the result in dest. Src and dest should have the same dimensions.
image_map_get_values map
This function returns a string containing, as a list, the 256 values in the lookup table of map.
