mlib_VolumeWindowLevel(3MLIB)				    mediaLib Library Functions				     mlib_VolumeWindowLevel(3MLIB)

NAME

       mlib_VolumeWindowLevel - window-level operation

SYNOPSIS

       cc [ flag... ] file... -lmlib [ library... ]
       #include <mlib.h>

       mlib_status mlib_VolumeWindowLevel(mlib_u8 *dst,
	    const mlib_s16 *src, mlib_s32 window, mlib_s32 level,
	    mlib_s32 gmax, mlib_s32 gmin, mlib_s32 len);

DESCRIPTION

       The mlib_VolumeWindowLevel() function performs a window-level operation by using the following equation:

       Printed copy or docs.sun.com displays an equation that represents the window-level operation.

       The window-level operation is represented by the following figure:

       Printed copy or docs.sun.com displays a figure that represents the window-level operation.

PARAMETERS

       The function takes the following arguments:

       dst	 Pointer to the output or destination array.

       src	 Pointer to the input or source array.

       window	 Width of the window.

       level	 Center of the window.

       gmax	 Maximum grayscale in the destination array.

       gmin	 Minimum grayscale in the destination array.

       len	 Length of the data array.

RETURN VALUES

       The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.

	    const mlib_f32 *src, void *filter, mlib_s32 n);

DESCRIPTION

       Each of these functions applies a biquad IIR filter to a signal array.

       Printed copy or docs.sun.com displays an equation that represents the biquad IIR filtering.

       The biquad IIR filter is represented by the following figure:

       Printed copy or docs.sun.com displays a figure that represents the biquad IIR filter.

PARAMETERS

       Each of the functions takes the following arguments:

       dst	 Destination signal array.

       src	 Source signal array.

       filter	 Internal filter structure.

       n	 Number of samples in the source signal array.

RETURN VALUES
