How to use the command 'ppmtoneo' (with examples)
The ppmtoneo command is a utility used to convert PPM (Portable Pixmap) images into Atari Neochrome files, with the file extension .neo. Neochrome is a graphics format used predominantly by the Atari ST computers, popular in the late 1980s and early 1990s. It was widely used by artists and developers who created graphics for games and other software on the Atari ST. Using ppmtoneo, you can adapt modern PPM images—commonly used in a number of graphics applications—so that they can be displayed in their original, pixel-perfect form on vintage Atari computing systems. More information on this command is available at Netpbm documentation

Convert a PPM image to a NEO file
Code:
ppmtoneo path/to/file.ppm > path/to/file.neo
Motivation:
This command is particularly useful for enthusiasts and developers in retro computing who wish to convert modern images into formats compatible with older hardware like the Atari ST. The process allows for reviving vintage systems with new content, often for purposes of education, nostalgia, or digital art restoration. By converting images from PPM to NEO, you preserve the classic aesthetic of these vintage systems while utilizing contemporary graphics tools for creation and editing beforehand.
Explanation:
ppmtoneo: This is the name of the command, indicating that the operation to be performed is converting a PPM image into the NEO file format. It’s a specialized command from the Netpbm package designed specifically for handling image conversions involving older file types.
path/to/file.ppm: This part specifies the path to the source PPM file you want to convert. Make sure that this path points to an existing PPM file. The PPM format is widely regarded for its simplicity in storing pixel data, making it a good choice for serving as an intermediary format for various image conversion tasks.
> path/to/file.neo: The
>symbol is used in shell commands to redirect output. The result of the conversion is directed to this location, which represents the destination file. The.neoextension indicates that the output file will be in the Atari Neochrome format, suitable for viewing on systems that support this vintage standard.
Example output:
Upon successful execution, you’ll have a new file located at path/to/file.neo. When opened on an Atari ST or an Atari ST emulator, this file will display the original image (from the file file.ppm) as it would have appeared on the Neochrome graphics editor. The Atari palette constraints and resolution will influence the visual output on vintage displays. The result holds significant educational or nostalgic value for those interested in the operational limits and visual appearance of historical computing platforms.
Conclusion
The ppmtoneo command serves as an important bridge between contemporary digital image standards and classic computing environments. Whether for the purpose of developing retro-style graphics, preserving digital history, or fostering an understanding of earlier computing ecosystems, this tool facilitates an important type of conversion. New generations of creators and technophiles are given the ability to experiment with and appreciate the unique artistic expression offered by systems like the Atari ST.
