Return the three parameters that define a Range for a specific twain capability. Many capabilities allow users to select their current value from a range of regularly spaced values. The capability can specify the minimum and maximum acceptable values and the incremental step size between values. For example, resolution might be supported from 100 to 600 in steps of 50 (100, 150, 200, ..., 550, 600).
Syntax
object.TwainGetCapRangeNumeric (nCap, *nMinValue, *nMaxValue, *nStepValue)
The TwainGetCapRangeNumeric syntax has these parts:
| Part | Description |
| object | Required. An object expression that evaluates to an object in the Applies To list. |
| nCap | Required. Long A TWAIN Capability constant. |
| *nMinValue | Required. Double. Output Starting value in the range. |
| *nMaxValue | Required. Double. Final value in the range. |
