ImageAcquire ClassTerminal Works - TwainScanning.Net Library
Class that allows to manipulate image capability supported by device. Allows an application to request the delivery of thumbnail representations for the set of images that are to be delivered. Setting CAP_THUMBNAILSENABLED to TRUE turns on thumbnail mode. Images transferred thereafter will be sent at thumbnail size (exact thumbnail size is determined by the Data Source). Setting this capability to FALSE turns thumbnail mode off and returns full size images. A successful set of this capability to TRUE will cause the Source to deliver image thumbnails during normal data transfer operations. This mode remains in effect until this capability is set back to FALSE. Application can use this capability to inquire, set, or restrict the values for BRIGHTNESS used in the Source.
