GammaCorrection
Overview
If GammaCorrection is set to a value other than 100 then the toolkit will apply gamma correction to a color image. The amount of gamma correction is equal to GammaCorrection / 100. For example, to achieve a gamma correction of 0.5 the property should be set to a value of 50.
Default value = 100
void STSetParameter(hBarcode, ST_GAMMA_CORRECTION, uint16 *value) ;
void STGetParameter(hBarcode, ST_GAMMA_CORRECTION, uint16 *value) ;
e.g
#include "barcode.h"
uint16 value = 1 ;
STSetParameter(hBarcode, ST_GAMMA_CORRECTION, &value) ;
