How to use the command ppmtoyuvsplit (with examples)

ppmtoyuvsplit is a command-line tool that allows you to convert a PPM image to three subsampled Abekas YUV files. It takes a PPM image as input and generates three YUV files with chroma subsampling. This can be useful for various applications that require working with YUV image data.

Use case 1: Convert a PPM image to three subsampled Abekas YUV files

Code:

ppmtoyuvsplit basename path/to/input_file.ppm

Motivation: You might want to use this use case when you have a PPM image that needs to be converted to three subsampled Abekas YUV files for further processing or analysis.

Explanation:

• basename: This is the specified basename for the output files. The tool will generate three output files with names starting with this basename.
• path/to/input_file.ppm: This is the path to the input PPM image file.

Example output: Suppose we have an input file named “input.ppm” and we want to generate YUV files with the basename “output”. After running the command ppmtoyuvsplit output input.ppm, the tool will convert the input PPM image to three subsampled Abekas YUV files named “output-0.yuv”, “output-1.yuv”, and “output-2.yuv” respectively.

Conclusion:

ppmtoyuvsplit is a powerful command-line tool for converting PPM images to three subsampled Abekas YUV files. It provides a convenient way to process and analyze YUV image data.
