IMAQ 12-bit/16bit monochrome buffer format - bitwise justification

[Richard Rudek]

I'm new to using the IMAQ software and PCI-1424 card, in addition to not
having access to an operational (IMAQ) system yet, so please be patient
with me.

I need to know how IMAQ "justifies" 12-bit data within the 16-bit buffer
format. ie LSB: 2047 -> 2047 (0x7FF), or MSB: 2047 -> 32752 (0x7FF0) ?.

Richard,

By your definition, it would be the LSB format. The higher bits are always zero. The values remain the same. It is just like converting a U8 to I16. Note that 16 bit images are signed (I16) not unsigned (U16).
