How to use the command `pnmtotiff` (with examples)

The pnmtotiff command is a utility that converts images from the Portable Any Map (PNM) format to the Tagged Image File Format (TIFF). Although this command has been superseded by pamtotiff, it remains useful for understanding file conversions within the broader scope of image processing, especially within scripting and older systems still utilizing PNM formats. TIFF files are widely used for their versatility and support for numerous color depths and compression schemes, making them ideal for archival and professional imaging tasks.

Use case 1: Viewing documentation for the pamtotiff command

Code:

tldr pamtotiff

Motivation:

When working with new or unfamiliar command-line utilities, consulting their documentation is vital for understanding their usage options, arguments, and functionality. The tldr tool provides concise and practical examples of command usage, making it a valuable resource for quickly grasping how pamtotiff works and how it can suit your needs in converting image files. Accessing such documentation helps streamline workflow processes and ensures proper command utilization.

Explanation:

• tldr: This command provides simplified, community-driven manual pages. It is particularly beneficial for users who prefer quick and clear explanations of commands without the complexity of traditional man pages.

• pamtotiff: The successor to pnmtotiff, this command also converts PNM files to TIFF format while offering enhanced functionality and features. By specifying pamtotiff, you instruct tldr to retrieve and display its documentation.

Example Output:

pamtotiff

Converts a Netpbm image stream into a TIFF image.

- Convert a PNM image to a TIFF image:
  pamtotiff input.pnm output.tiff
  
- Convert a PNM image to a TIFF image with a specific compression:
  pamtotiff -compression <algorithm> input.pnm output.tiff

Conclusion:

The pnmtotiff command serves as an effective tool for converting images from the flexible and simple PNM format to the broadly compatible and highly detailed TIFF format. Even though newer tools like pamtotiff have taken its place, understanding how to access documentation and examples through tools like tldr facilitates a smoother transition and maximizes the potential the command offers. This enhances proficiency in managing image conversions across different file formats, ultimately empowering users in both technical and creative domains.
