• --lighten <0-100>: Lightens the image by the specified percentage.
• --darken <0-100>: Darkens the image by the specified percentage.
• --inverse: Creates an inverse image (negative).
• --bw: Converts the image to grayscale.
• --sharpen: Applies a sharpening filter to the image.
• --blur: Applies a blurring filter to the image.
• --ed: Applies the Sobel–Feldman edge detection filter.
• --rc: Applies the Roberts cross edge detection filter.
• --rotate [90, 180, 270]: Rotates the image 90, 180, or 270 degrees to the right.
