Is your feature request related to a problem? Please describe. No problem

Describe the solution you'd like Some type of feature or function that can shift an image horizontally or vertically by a percentage, pixel amount, or phase (90 degrees, 180 degrees etc).

Describe alternatives you've considered Manually cutting the image and shifting it, which is super slow.

Additional context None really.

研究方向
Investigate current image manipulation functions in Jimp to understand pixel format. Propose and implement a shift function that takes parameters for direction (horizontal/vertical), amount (pixels, percentage, or phase). Consider edge cases like wrapping vs. cropping. Look at similar libraries for reference.
