Syntax

short IntensityDetect (ILEADRaster *pRaster, short iLow, short iHigh, OLE_COLOR crIn, OLE_COLOR crOut, short iChannel);

Overview

Refer to Detecting and Enhancing Edges and Lines.

Remarks

Applies binary segmentation to a bitmap by filtering the specified bitmap to detect colors in a specified intensity range, in the specified color channel(s).

The image is divided into two parts inner and outer according to the values of iLow and iHigh.

The method can process 2 or more channels at a time by OR-ing two or more flags.

This method supports 12 and 16-bit grayscale images and 48 and 64-bit color images. Support for 12 and 16-bit grayscale images and 48 and 64-bit color images is available only in the Document/Medical toolkits.

This method does not support signed data images. It returns the error code ERROR_SIGNED_DATA_NOT_SUPPORTED if a signed data image is passed to this method.
