|
+Description
|
|
+===========
|
|
+
|
|
+This is a packed grey-scale image format with a depth of 12 bits per
|
|
+pixel. Two consecutive pixels are packed into 3 bytes. The first 2 bytes
|
|
+contain the 8 high order bits of the pixels, and the 3rd byte contains the 4
|
|
+least significants bits of each pixel, in the same order.
|
|
+
|
|
+**Byte Order.**
|
|
+Each cell is one byte.
