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.
