NAME

       LqrColDepth - carver objects colour depth specification

DESCRIPTION

       The default LqrCarver object constructor lqr_carver_new uses a colour depth of 8 bits per channel, and
       therefore its input must be an array of unsigned chars. However, the LqrCarver objects can handle images
       of grater colour depth, if they are created with the lqr_carver_new_ext constructor. The possible colour
       depths are specified through variables of type LqrColDepth, which is an enum type; its possible values,
       and the type of the input buffer associated with them, are:

       LQR_COLDEPTH_8I
           use type guchar (8 bit unsigned integers) - the default

       LQR_COLDEPTH_16I
           use type guint16 (16 bit unsigned integers)

       LQR_COLDEPTH_32F
           use type gfloat (32 bit floating point)

       LQR_COLDEPTH_64F
           use type gdouble (64 bit floating point)

       These values are also relevant when reading out a LqrCarver object with the functions lqr_carver_scan_ext
       or lqr_carver_scan_line_ext, since the readout buffer must be cast to the appropriate type to be actually
       read.

       The colour depth of an LqrCarver object can be obtained with the function lqr_carver_get_col_depth.
