## NAME

pamstretch-gen - use pamstretch and pamscale to scale by non-integer values

## SYNOPSIS

**pamstretch-gen** *N* \[*pnmfile*\]

## DESCRIPTION

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

**pamstretch-gen** is a program which uses [**pamstretch**(1)](/pamstretch/1.md)  and [**pamscale**(1)](/pamscale/1.md)  to scale up a Netpbm image smoothly by any factor; it's like a more general version of **pamstretch** (hence the name).

**pamstretch-gen** uses the **-dropedge** option on **pamstretch**.

## OPTIONS

There are no command line options defined specifically for **pamstretch-gen**, but it recognizes the options common to all programs based on libnetpbm (See \
  Common Options ⟨index.html#commonoptions⟩ .)

The Netpbm global options **-quiet** and **-plain** did not exist on **pamstretch-gen** prior to version 10.86 (March 2019). **-quiet** did not work until version 10.91 (June 2020).

## SEE ALSO
