LBitmap::StretchIntensity

#include "ltwrappr.h"

virtual L_INT LBitmap::StretchIntensity(void);

Increases the contrast in the class object's bitmap by centering, maximizing, and proportioning the range of intensity values.

Returns

SUCCESS

The function was successful.

< 1

An error occurred. Refer to Return Codes.

Comments

Unlike the LBitmap::ChangeContrast function, this function always retains the original number of different intensity values. (Ordinary contrast adjustments can lose values at the high and low ends of the scale.)

To update a status bar or detect a user interrupt during execution of this function, refer to LBase::EnableStatusCallback.

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