Using the Command ppmflash (with examples)

Generate a PPM image that is flashfactor times brighter than the input PPM image

Code:

ppmflash flashfactor path/to/file.ppm > path/to/file.ppm

Motivation:

This use case is useful when you want to increase the brightness of a PPM image. By specifying a flashfactor, you can control how much brighter the output image should be compared to the input image. Increasing the brightness can enhance the details and visibility of the image. This can be particularly useful in scenarios where the input image is underexposed or lacks sufficient brightness.

Explanation:

• flashfactor: This argument specifies how much brighter the output image should be compared to the input image. The flashfactor is a decimal number greater than 1. For example, a flashfactor of 2 would make the output image twice as bright as the input image.
• path/to/file.ppm: This argument specifies the path to the input PPM image file. Replace path/to/file.ppm with the actual file path.

Example Output:

By running the command ppmflash 1.5 input.ppm > output.ppm, the output image output.ppm would be 1.5 times brighter than the input image input.ppm.

Display version

Code:

ppmflash -version

Motivation:

This use case is helpful when you want to check the version of the ppmflash command installed on your system. It is essential to know the version to ensure compatibility with other tools or to seek help from the ppmflash community.

Explanation:

• -version: This argument is used to display the version of the ppmflash command.

Example Output:

Running the command ppmflash -version would display the version information of the ppmflash command, such as ppmflash v1.2.3.
