Leadtools.Twain Namespace > TwainSession Class : ModifyRgbResponse Method




elements
Array of RGB elements that contain the data to be set.
bitsPerPixel
Bits per pixel to be set. This is used to determine the number of RGB elements.
flags
Flags that indicate the function behavior.
Sets the RGB elements to be used when transferring data from the current TWAIN source.

Syntax

Visual Basic (Declaration)
