IMAGESIN

Description

Finds the sine values in a raster image file and places those values in the specified output file.

Parameters

Name	Type	Caption	Length	Value range
FILI *	String	Input file name	1 - 192
FILO	String	Output file name	0 - 192
DBIC *	Integer	Input raster channel(s)	1 -
DBOC	Integer	Output raster channel(s)	0 -
MONITOR	String	Monitor mode	0 - 3	ON, OFF Default: ON

* Required parameter

Parameter descriptions

FILI

Specifies the name of the PCIDSK file that contains the raster channels to process.

FILO

Specifies the name of the PCIDSK image file to receive the output channel(s). If this parameter is not specified, the output file is assumed to be the same as the input file (FILI). If FILO already exists, its projection must be the same as FILI.

If FILO does not exist, a new PCIDSK file will be created. By default, the georeferencing information from FILI will be copied to the new FILO.

DBIC

Specifies the input channel(s) to be processed.

Ranges of channels or segments can be specified with negative values. For example, {1,-4,10} is internally expanded to {1,2,3,4,10}. When you are not specifying a range in this way, only 48 numbers can be specified explicitly.

DBOC

Specifies the output image channel(s) produced by taking the sine of the input image channels (DBIC).

If FILO is an existing file, DBOC must be specified, and the channel type must be CHN_32R.

The number of output channels (DBOC) must be the same as the number of input channels (DBIC).

Ranges of channels or segments can be specified with negative values. For example, {1,-4,10} is internally expanded to {1,2,3,4,10}. When you are not specifying a range in this way, only 48 numbers can be specified explicitly.

MONITOR

The program progress can be monitored by printing the percentage of processing completed. A system parameter, MONITOR, controls this activity.

Available options are:

• ON: Turns the monitor ON (default)
• OFF: Turns the monitor OFF (recommended if running in batch or background mode)

Details

IMAGESIN takes all the pixel values from the input channel(s) and calculate the sine value, placing those values in the specified output channel(s).

Example

This example demonstrates the use of IMAGESIN.

EASI>fili	=	"irvine.pix"	! input file
EASI>filo	=	"output.pix"	! output file (will be created)
EASI>dbic	=	1, -5	! input channels
EASI>dboc	=	1, -5	! output channels
