--highlight value        

 

Sets the highlight value for the images to be acquired. The device must support setting highlight values.  Some devices do not support setting the highlight level.  The --verbose option will generate a message that will inform whether setting the highlight value worked successfully or an error was encountered.

 

The highlight value can be any numeric value between 0 and 255, inclusive.

 

The highlight setting is an advanced setting that allows the device to set a minimum "light" color that the image will use.  Any color that would be lighter than the highlight is equal to the highlight value.  See also --shadow to set the darkest color to use in the image.

 

Example:  Acquire a BMP image named test.bmp.  The color is RGB, and the highlight value used is 70.

 

twainsave --filename test.bmp --color 2 --highlight 70

 

Default Setting:

The highlight value that the device determines as the default.
