Extract Byte Plane
The Extract Byte Plane command extracts
single byte planes from an image having more than 1 byte per pixel.
The result is an image containing the bit component of the original
image offset by 8 bits for Byte 2, 16 bits for byte 3, and so on.
If the image has greater than 8-bit (1 byte) bit depth and more
than a single byte plane is extracted, the byte plane images may be
saved either as single images in separate windows or as an
Image Set in a single window.
-
The Extract Byte Plane command opens from
the Image Window > Process >
Math menu and button on the
Main Toolbar. The "immediate" form,
shown first, opens when an image or image set is displayed in the
top-most window. The general form can be used to select source
images from folders, windows, or by matching templates.
Extract Byte Plane Properties

Profile [|>]

Selects the parameter profile for this command and
allows you to save or work with existing presets.

[Select]

Opens the
Select Source Images dialog to choose images from an
image window, folder, files, name template, or a Mira File
List.

Extract
|
Check these boxes to select byte planes to
extract. Each byte plane creates a new image.
Byte
1 extracts the first byte plane at offset zero (i.e., the
lowest order byte), and so on, through the 8-th byte.

Create Image Set
|
Check this box to extract the channel images to an
Image Set in a single image window.
|
For integer type images, the pixel values in the
original image are the sum of scaled values in each byte planes,
where each plane has scale factor 1, 256, 256*256, and so on. For
example, suppose the original image is unsigned 16-bit type and a
pixel value is 2200, Then 2200 is represented by bytes 1 and 2 as
2200 = 8*(256) + 152. Thus byte plane 1 (the least significant
byte) would have value 152 and byte plane 2 would have value 8.
