SYNOPSIS
bmptoppm [bmpfile]
DESCRIPTION
bmptoppm reads a Microsoft Windows or OS/2 BMP file as input and produces a PPM (Portable PixMap) color image as output. This is part of the Netpbm package.This command was replaced in Netpbm 9.25 (March 2002) by bmptopnm, which automatically determines the appropriate output format (PBM, PGM, or PPM) based on the input image characteristics. bmptoppm is retained only for backward compatibility and takes no options of its own.Input can be from a file or standard input; output is to standard output.
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
For grayscale BMP images, consider using bmptopnm instead, which will produce more appropriate PGM output. This command always outputs PPM regardless of the input color depth.
