width.
Offset in X direction of center of image, relative to the bar code center, using Intelligent Bar Code
Units (page 2-65).
Offset in Y direction of the center of the image, relative to the bar code center, using Intelligent Bar
Code Units. Positive Y is above the bar code center, and negative Y is below the center.
Width of image, using Intelligent Bar Code Units.
Height of image, using Intelligent Bar Code Units.
The number of pixels to use per Intelligent Bar Code Unit. A higher resolution yields a better quality
image, but also a larger one. The exact value of resolution required is dependent on how far away
the Imager is from the image, and how high the desired image quality.
Format of image. The following formats are supported:
FF_RAW_BINARY
FF_RAW_GRAY
Raw data that's converted to 2 gray levels
Raw data that's converted to 256 gray levels
