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.
