CapStep Property

Description

Gets the step value in a range when the CapType is TWCAP_RANGE.

Property Type

Read-only property

Syntax

Visual Basic
Public Property CapStep As Single

Return Type

A single value which represents the step value in a range.

Remarks

This is a runtime, read-only property.

This is the increment the Twain device prefers when setting a new value. For example, if Capability = TWCAP_XRESOLUTION, CapMin = 100, CapMax = 600 and CapStep = 100, then a legal new value would be in the range of 100 - 600 in increments of 100.

If a non-step aligned value is set to the Capability, no error is generated, and the Twain device will most likely round to the nearest step.

The step value can only be read, therefore, there is no corresponding property to set the step value.
