Convert any image format to PNM (Netpbm)
TLDR
Convert any image to PNM format
$ anytopnm [input.jpg] > [output.pnm]
Convert with verbose output$ anytopnm -v [input.png] > [output.pnm]
SYNOPSIS
anytopnm [-v] file
DESCRIPTION
anytopnm is a Netpbm utility that converts images from virtually any format to PNM (Portable Any Map) format. It acts as a wrapper, detecting the input format and calling the appropriate converter automatically.PNM is an intermediate format in the Netpbm toolkit, useful for image processing pipelines where a common format simplifies conversions between any two formats.
PARAMETERS
-v
Verbose output showing conversion stepsfile
Input image file (uses stdin if omitted, but stdin must be seekable)
INSTALL
sudo apt install netpbm
sudo dnf install netpbm
sudo pacman -S netpbm
sudo apk add netpbm
sudo zypper install netpbm
brew install netpbm
nix profile install nixpkgs#netpbm
CAVEATS
Depends on having the correct format-specific converter installed. Some formats may require additional libraries. Output is always PNM; use other tools to convert to different target formats.
HISTORY
anytopnm is part of the Netpbm package, which evolved from the original PBMPLUS toolkit created by Jef Poskanzer in the late 1980s.
