Data Type:

TW_UINT16

Purpose:

Unless a quantity is dimensionless or uses a specified unit of measure, ICAP_UNITS determines the unit of measure for all quantities.

Applications should be able to handle TWUN_PIXELS, if they want to support data transfers from "dimensionless" devices such as digital cameras.

Valid Values:

• TWUN_INCHES = 0
• TWUN_CENTIMETERS = 1
• TWUN_PICAS = 2
• TWUN_POINTS = 3
• TWUN_TWIPS = 4
• TWUN_PIXELS = 5

Default Value:

TWUN_INCHES
