| IsBitonal(Int32) | Determines whether a GdPicture image or the area defined by SetROI() method is composed of black and white pixels only. This method uses a linear formula to determine the color intent. To obtain more accurate result the ColorDetection() method should be used instead. |
| IsBitonal(Int32,Int32) | Determines whether a GdPicture image or the area defined by SetROI() method is composed of black and white pixels only. This method uses a linear formula to determine the color intent. To obtain more accurate result the ColorDetection() method should be used instead. This method accepts a threshold parameter which speaks to the confidence of the detection. Low Threshold values will require high confidence for the image to be determined as bitonal, and high values will require low confidence for the image to be determined as bitonal. |
