Notes

• The name argument can be a BoxImage object or the name of an image variable in the current context.

• The operation modifies the image in place when used as a member function.

• Returns the modified image object for chaining or further processing.

• The gain argument should be a positive number; higher values produce a stronger sharpening effect.
