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.
