VCDPropertyItem

A VCDPropertyItem object provides the functionality to access a video capture device property.

Usage

A VCDPropertyItem is retrieved from a VCDPropertyItems collection. It provides the property's elements ( VCDPropertyElement ) like "range", "auto" etc. It also provides the property's name and identifier string.

A property item can contain one or more VCDPropertyElements. It may contains a VCDPropertyElement that provides the property's value and a second VCDPropertyElement that provides the automation switch.

Sample

The method VCDPropertyItems.FindItem is used to retrieve a VCDPropertyItem. The property to be retrieved is specified by an item identifier string. To retrieve the brightness property, the string VCDID_Brightness is used. The item identifier strings are defined in the class VCDPropertyIDs. The source code of this class can be found in VCDPropertyID.vb and VCDPropertyID.cs respectively.

Dim Brightness As TIS.Imaging.VCDPropertyItem Brightness = IcImagingControl1.VCDPropertyItems.FindItem(TIS.Imaging.VCDIDs.VCDID_Brightness)
