How to use the command pgmtost4 (with examples)

The pgmtost4 command is a tool that can be used to convert a PGM (portable graymap) image file to the SBIG ST-4 format. PGM is a simple grayscale image format that is commonly used for handling images in computer graphics. On the other hand, the SBIG ST-4 format is a proprietary format specific to the SBIG ST-4 camera. The pgmtost4 command allows users to convert PGM images to the SBIG ST-4 format, which can be useful for compatibility or integration purposes.

Use case 1: Convert a PGM image file to the SBIG ST-4 format

Code:

pgmtost4 path/to/input_file.pgm > path/to/output.st4

Motivation: The motivation for using this example is to convert a PGM image file to the SBIG ST-4 format. This can be useful in scenarios where the user wants to work with PGM images in the SBIG ST-4 format or when compatibility with SBIG ST-4 cameras is required.

Explanation:

• pgmtost4: This is the command that invokes the pgmtost4 tool. It takes a PGM image file as input and converts it to the SBIG ST-4 format.
• path/to/input_file.pgm: This is the path to the input PGM image file that needs to be converted to the SBIG ST-4 format.
• >: This is a redirection operator in the shell that redirects the output of the pgmtost4 command to a file instead of printing it to the console.
• path/to/output.st4: This is the path to the output file where the converted SBIG ST-4 format image will be saved.

Example output: The PGM image file located at path/to/input_file.pgm will be converted to the SBIG ST-4 format and saved at path/to/output.st4.

Conclusion:

The pgmtost4 command is a useful tool for converting PGM image files to the SBIG ST-4 format. By providing a simple and straightforward way to perform this conversion, it enables users to work with PGM images in the SBIG ST-4 format or achieve compatibility with SBIG ST-4 cameras.
