The ‘yuvtoppm’ command is used to convert Abekas YUV bytes to PPM (Portable Pixmap) format. It takes an input file containing the YUV bytes, converts them to a PPM image, and saves the image in the specified output file.

Use case 1: Convert YUV bytes to PPM format

Code:

yuvtoppm width height path/to/input_file.yuv > path/to/output_file.ppm

MOTIVATION: Converting YUV bytes to PPM format is useful when working with video or image processing tasks. PPM format is commonly used for image manipulation and analysis, and converting YUV bytes to PPM allows us to utilize the features and tools available for PPM images.

EXPLANATION:

• ‘yuvtoppm’: The command being used.
• ‘width’: The width of the YUV image in pixels.
• ‘height’: The height of the YUV image in pixels.
• ‘path/to/input_file.yuv’: The path to the input file containing the YUV bytes.
• ‘path/to/output_file.ppm’: The path where the converted PPM image will be saved.

EXAMPLE OUTPUT: Assuming we have an input file ‘input.yuv’ with width 640 and height 480, executing the command:

yuvtoppm 640 480 path/to/input.yuv > path/to/output.ppm

will convert the YUV bytes in ‘input.yuv’ to PPM format and save the resulting image as ‘output.ppm’ in the specified output path.

Conclusion:

The ‘yuvtoppm’ command provides a convenient way to convert Abekas YUV bytes to PPM format. It allows users to utilize the capabilities of PPM images for analysis or further image processing tasks. By following the provided use cases, users can easily convert their YUV data to PPM format and explore the possibilities offered by PPM images.
