eyuvtoppm (with examples)
Use Case 1: Convert a Berkeley YUV file to PPM
Code:
eyuvtoppm --width width --height height path/to/input_file.eyuv > path/to/output_file.ppm
Motivation:
The motivation for using this command is to convert a Berkeley YUV file into a PPM image format. PPM (Portable Pixmap) is a widely supported file format that can be used for storing images. By converting the YUV file to PPM, we can easily view and manipulate the image using various image editing software.
Explanation:
--width width: Specifies the width of the output image in pixels.--height height: Specifies the height of the output image in pixels.path/to/input_file.eyuv: Specifies the path to the input Berkeley YUV file.path/to/output_file.ppm: Specifies the path to the output PPM file.
Example Output:
The command eyuvtoppm --width 1920 --height 1080 path/to/input_file.eyuv > path/to/output_file.ppm converts a Berkeley YUV file to a PPM image with a resolution of 1920x1080 pixels. The resulting PPM image is stored in the specified output file.
Use Case 2: Convert a Berkeley YUV file to PPM and display it on the screen
Code:
eyuvtoppm --width width --height height path/to/input_file.eyuv | display
Motivation:
The motivation for using this command is to convert a Berkeley YUV file to a PPM image and display it on the screen. This can be useful for quickly previewing the content of the YUV file without saving it to a separate file.
Explanation:
--width width: Specifies the width of the output image in pixels.--height height: Specifies the height of the output image in pixels.path/to/input_file.eyuv: Specifies the path to the input Berkeley YUV file.display: A command used to display images on the screen. It reads the converted PPM image from the standard input.
Example Output:
The command eyuvtoppm --width 1280 --height 720 path/to/input_file.eyuv | display converts a Berkeley YUV file to a PPM image with a resolution of 1280x720 pixels and displays it on the screen using the display command.
Use Case 3: Convert a Berkeley YUV file to PPM and process it with another command
Code:
eyuvtoppm --width width --height height path/to/input_file.eyuv | another_command
Motivation:
The motivation for using this command is to convert a Berkeley YUV file to a PPM image and process it further with another command. This allows for additional manipulation or analysis of the image using different tools or algorithms.
Explanation:
--width width: Specifies the width of the output image in pixels.--height height: Specifies the height of the output image in pixels.path/to/input_file.eyuv: Specifies the path to the input Berkeley YUV file.another_command: A command that can process PPM images. It reads the converted PPM image from the standard input.
Example Output:
The command eyuvtoppm --width 640 --height 480 path/to/input_file.eyuv | another_command converts a Berkeley YUV file to a PPM image with a resolution of 640x480 pixels and processes it with another_command. The specific output would depend on the functionality of another_command.
Conclusion:
The eyuvtoppm command is a versatile tool for converting Berkeley YUV files to PPM images. The provided examples demonstrate different use cases, including converting to PPM and storing it in a file, displaying the converted image on the screen, and processing the converted image with another command. By utilizing these examples, users can easily perform various operations on Berkeley YUV files and manipulate the resulting PPM images as needed.
