# pamwipeout(1)

replace detail with smooth gradient from one edge to the other

## NAME

pamwipeout - replace detail with smooth gradient from one edge to the other

## SYNOPSIS

**pamwipeout** {**-lr \| -tb**} \[*filename\]*

*Minimum unique abbreviation of options is acceptable.*  *You may use double hyphens instead of single hyphen to denote options.*

## DESCRIPTION

*This program is part of* **Netpbm**(1) *.*

**pamwipeout** *replaces every row or column (as directed) with a smooth* *gradient between the pixel values at each edge.  You can use it in combination* *with* **pamcut** *and* **pnmpaste** */* **pamcomp** *to remove unwanted* *parts of a larger image.*

*In* **top-bottom** *mode, the program reads the whole image into memory* *before it can start processing.  In* **left-right** *it will read the image a* *row at the time, process that row and write it to the output file.  Therefore,* *in case of very large images, it may be better to use instead of* *"***pamwipeout -tb***" a pipe of "***pamflip -cw \| pamwipeout -lr \| pamflip** **-ccw***".*

## PARAMETERS

*Filename is the name of the input file. If you don't* *specify this,* **pamwipeout** *reads the image from Standard Input.*

## OPTIONS

*In addition to the options common to all programs based on libnetpbm* *(most notably* **-quiet***, see* \
  *Common Options* ⟨index.html#commonoptions⟩ *),* **pamwipeout** *recognizes the following* *command line options:*

- **-tb** *\|* **-lr**

  *This option chooses between a vertical and a horizontal gradient.  You must* *specify one of these, but not both.*

## SEE ALSO

**pam**(1)  *and* [**pamflip**(1)](/pamflip/1.md) *,* [**pamcut**(1)](/pamcut/1.md) *,* [**pamcomp**(1)](/pamcomp/1.md) *,* [**pnmpaste**(1)](/pnmpaste/1.md) *.*

## HISTORY

**pamwipeout** *was new in Netpbm 10.54 (March 2011).*

*A predecessor program (not part of Netpbm) was called* **pnmblend***.*

## AUTHORS

*Willem van Schaik* *wrote this program in January 2011 and contributed it to Netpbm.*
