LogDensity Object Class

Defined Functions

The following functions are defined for creating and manipulating a LogDensity object.

Function Name Description
XintCreateLogDensity Creates a LogDensity object.
XintLogDensityGetData Retrieves depth and sample data from a LogDensity object.
XintLogDensityTopAndBot tom Returns the top and bottom depth values of the specified l og density.

Function Name	Description
XintCreateLogDensity	Creates a LogDensity object.
XintLogDensityGetData	Retrieves depth and sample data from a LogDensity object.
XintLogDensityTopAndBot tom	Returns the top and bottom depth values of the specified l og density.

XintCreateLogDensity

XintCreateLogDensity creates a LogDensity object. Note: LogDensity objects do not need to be managed.

     Object XintCreateLogDensity (...)

Widget parent Parent of new LogDensity object.
char * name Name of new LogDensit y object.
ArgList arglist List of resource/ value items.
Cardinal argcount Number of items in arglist.

XintLogDensityGetData

XintLogDensity returns two data arrays containing the sample and depth values of a LogDensity object within a specified depth range. The data pointers returned point directly to the internal LogDensity data structures. The corresponding memory should not be deallocated by the application.

     void XintLogDensityGetData (...)

Object object ID of the LogDensity object.
float start_depth Specifies the s tarting depth.
float end_depth Specifies the end ing depth.
float ** sample_array Returns a p ointer to the array containing the sample data.
float ** depth_array Returns a po inter to the array containing the depth data.
int * sample_count Returns the nu mber of samples.

XintLogDensityTopAndBottom

This function returns the top and bottom depth values of a LogDensity object.

     void XintLogDensityTopAndBottom (...)

Object object ID of the LogDensity object.
float * top Returns the top depth of the LogDensity
float * bottom Returns the bottom depth of the LogDensity

Macros

Macro XintIsLogDensity returns True if the specified object is a LogDensity object.

     Boolean XintIsLogDensity (Object object)

Widget	parent	Parent of new LogDensity object.

Object	object	ID of the LogDensity object.
float	start_depth	Specifies the s tarting depth.
float	end_depth	Specifies the end ing depth.
float **	sample_array	Returns a p ointer to the array containing the sample data.
float **	depth_array	Returns a po inter to the array containing the depth data.
int *	sample_count	Returns the nu mber of samples.
