> **TLDR:** Cut out a rectangular region from a Netpbm image.
>
- Discard the specified number of columns/rows on each side of the image:
  `pamcut {{-cropl|-cropleft}} {{value}} {{-cropr|-cropright}} {{value}} {{-cropt|-croptop}} {{value}} {{-cropb|-cropbottom}} {{value}} {{path/to/image.ppm}} > {{path/to/output.ppm}}`
- Keep only the columns between the specified columns (inclusively):
  `pamcut {{-l|-left}} {{value}} {{-ri|-right}} {{value}} {{path/to/image.ppm}} > {{path/to/output.ppm}}`
- Fill missing areas with black pixels if the specified rectangle does not entirely lie within the input image:
  `pamcut {{-t|-top}} {{value}} {{-b|-bottom}} {{value}} -pad {{path/to/image.ppm}} > {{path/to/output.ppm}}`

## NAME
       pamcut - cut a rectangle out of a PAM, PBM, PGM, or PPM image

## SYNOPSIS
       **pamcut**  [**-left**  _leftcol_]  [**-right**  _rightcol_] [**-top** _toprow_] [**-bottom** _bottomrow_] [**-width** _width_]
       [**-height** _height_] [**-pad**] [**-verbose**] [ _left_ _right_ _width_ _height_ ] [_pnmfile_]

       All options may be abbreviated to the shortest unique prefix.


## DESCRIPTION
       Reads a PAM, PBM, PGM, or PPM image as input.  Extracts the specified rectangle, and produces
       the same kind of image as output.

       There  are two ways to specify the rectangle to cut: arguments and options.  Options are eas‐
       ier to remember and read, more expressive, and allow you to use defaults.  Arguments were the
       only way available before July 2000.

       If  you  use  both  options and arguments, the two specifications get mixed in an unspecified
       way.

       To use options, just code any mixture of  the  **-left**,  **-right**,  **-top**,  **-bottom**,  **-width**,  and
### -height
       specify all three of **-left**, **-right**, and **-width** or **-top**, **-bottom**, and **-height**.

       To use arguments, specify all four of the _left_, _right_, _width_, and _height_ arguments.  _left_ and
       _top_  have  the  same effect as specifying them as the argument of a **-left** or **-top** option, re‐
       spectively.  _width_ and _height_ have the same effect as specifying them as the  argument  of  a
### -width -height
       tive, they have the same effect as specifying one less than the value as the  argument  to  a
### -right -bottom
       right edge).  Before July 2000, negative numbers were not allowed for _width_ and _height_.

       Input is from Standard Input if you don't specify the input file _pnmfile_.

       Output is to Standard Output.

       If you are splitting a single image into multiple same-size images, **pamdice**  is  faster  than
       running **pamcut** multiple times.


## OPTIONS
### -left
              ber, it refers to columns numbered from 0 at the left, increasing to  the  right.   If
              negative, it refers to columns numbered -1 at the right, decreasing to the left.

### -right
              for **-left.**

### -top
              refers  to  rows  numbered  from  0  at the top, increasing downward.  If negative, it
              refers to columns numbered -1 at the bottom, decreasing upward.

### -bottom
              The row number of the bottom-most row to be in the output, numbered the  same  as  for
              **-top**.

### -width

### -height
              The number of rows to be in the output.  Must be positive.

### -pad
              less you also specify **-pad**.  In that case, it pads the output with  black  up  to  the
              edges  you  specify.   You can use this option if you need to have an image of certain
              dimensions and have an image of arbitrary dimensions.

              **pnmpad** also adds borders to an image, but you specify their width directly.


### -verbose
              Print information about the processing to Standard Error.
