.SH DESCRIPTION
.BR QccIMGImageComponentScalarQuantize()
calls
.BR QccSQScalarQuantization (3)
for each pixel in
.IR image_component ,
effectively scalar quantizing the pixel with
.IR quantizer .
The resulting quantization indices are returned in
.IR channel
which must be allocated prior to calling
.BR QccIMGImageComponentScalarQuantize() .
If
.IR distortion
is not
.BR NULL ,
the squared-error distortion between each pixel and its quantized
reconstruction is returned in
.IR distortion .
.LP
.BR QccIMGImageComponentInverseScalarQuantize()
inverse quantizes the quantization indices in
.IR channel ,
reconstructing the pixels which are returned in
.IR image_component .
.LP
.BR QccIMGImageScalarQuantize()
and
.BR QccIMGImageInverseScalarQuantize()
call
.BR QccIMGImageComponentScalarQuantize()
and
.BR QccIMGImageComponentInverseScalarQuantize() ,
respectively, for each of the
.IR Y ,
.IR U ,
and
.IR V
components of
.IR image .
.IR quantizers
and
.IR channels
are arrays of quantizers and channels,
one for each image component.
.SH "RETURN VALUE"
These routines return 0 on success, 1 on failure.
