vexp(1)

PROGRAM
vexp - Compute the base 10 antilogarithm of an image with an operation gating image.

SYNTAX

vexp

-i  input image

-o  resulting output image

[-m]
    add operation masking image

[-t]
    Do not subtract 1 from result [False] Subtract 1 from result [True]

[-V]
    Gives the version for vexp

[-U]
    Gives the usage for vexp

[-P]
    Prompts for command line options

[-A [file1]]
    Creates the answer file called vexp.ans or file1

[-a [file1]]
    Uses vexp.ans or file1 as the answer file

DESCRIPTION
vexp computes the antilogarithm of an image pixel by pixel with an operation gating image. The antilogarithm is the same as 10 raised to the value of the image pixel, exp10(x).

The optional mask image must be of the same data storage type and size as the input image, and is used to gate the operation. A non-zero mask pixel enables the output pixel to contain the exp10(x). A zero mask pixel just transfers the value of the corresponding pixel in the input image to the output image.

REQUIRED ARGUMENTS

-i  type: infile
    desc: input image

-o  type: outfile
    desc: resulting output image

OPTIONAL ARGUMENTS

-m  type: infile
    desc: add operation masking image

-t  type: boolean
    desc: Do not subtract 1 from result [False] Subtract 1 from result [True]
    default: true

EXAMPLES
vexp -i input.image -o output.image -m mask.image -t 0

This performs a bitwise exponential on input.image, uses masking image mask.image, and places the result in output.image. The -t 0 indicates that 1 will not be subtracted from the result of the exponent.
