W - Histogram Ship
A histogram gives a quick picture of the tonal range of an image, or key type.
A low-key image has detail concentrated in the shadows; a high-key image
has detail concentrated in the highlights; and an average-key image has
detail concentrated in the midtones. This modifier ships the histogram for
an image.

Image Size Compatibility
If you prefer that an image ship returns images at the sensor’s native resolution
(752x480 pixels for the 5X00 engine, 640x480 pixels for the 4X00 engine), scan
the Native Resolution code. If you have an image scanner with a 4X00 image
engine and have designed applications that expect an image ship to return
exactly 640x480 pixels, scan the Force VGA Resolution barcode. Refer to
"Show Engine Revision" on page 11-1 for information on determining the engine
in your unit. Default = Force VGA Resolution
