Technically, the JPEG format uses the YCbCr colorspace (which technically is

|

<p>
|

Each plane is simply a 2D array of bytes, each byte representing the value
|
||||
of one of the components (Y, Cb, or Cr) at a particular location in the
|
||||
image. The width and height of each plane are determined by the image
|
||||
width, height, and level of chrominance subsampling. The luminance plane
|
||||
width is the image width padded to the nearest multiple of the horizontal
|
||||
subsampling factor (2 in the case of 4:2:0 and 4:2:2, 4 in the case of
|
||||
4:1:1, 1 in the case of 4:4:4 or grayscale.) Similarly, the luminance plane
|
||||
height is the image height padded to the nearest multiple of the vertical
|
||||
subsampling factor (2 in the case of 4:2:0 or 4:4:0, 1 in the case of 4:4:4
|
||||
or grayscale.) The chrominance plane width is equal to the luminance plane
|
||||
width divided by the horizontal subsampling factor, and the chrominance
|
||||
plane height is equal to the luminance plane height divided by the vertical
|
||||
subsampling factor.
|
||||
subsampling factor (1 in the case of 4:4:4, grayscale, or 4:4:0; 2 in the
|
||||
case of 4:2:2 or 4:2:0; 4 in the case of 4:1:1.) Similarly, the luminance
|
||||
plane height is the image height padded to the nearest multiple of the
|
||||
vertical subsampling factor (1 in the case of 4:4:4, 4:2:2, grayscale, or
|
||||
4:1:1; 2 in the case of 4:2:0 or 4:4:0.) This is irrespective of any
|
||||
additional padding that may be specified as an argument to the various
|
||||
YUVImage methods. The chrominance plane width is equal to the luminance
|
||||
plane width divided by the horizontal subsampling factor, and the
|
||||
chrominance plane height is equal to the luminance plane height divided by
|
||||
the vertical subsampling factor.
|
||||
<p>
|
||||
For example, if the source image is 35 x 35 pixels and 4:2:2 subsampling is
|
||||
used, then the luminance plane would be 36 x 35 bytes, and each of the
|
||||
chrominance planes would be 18 x 35 bytes. If you specify a line padding of
|
||||
4 bytes on top of this, then the luminance plane would be 36 x 35 bytes, and
|
||||
each of the chrominance planes would be 20 x 35 bytes.</div>
|

chrominance planes would be 18 x 35 bytes. If you specify a row alignment
