This is a seamless oupainting workflow for the Flux.1 dev model, which requires no prompts. It can seamlessly join image borders without leaving traces and allows for local image expansion, all without the need for any prompt words.
1. 蒙版设置 mask

蒙版的涂抹方式有两种（默认第一种）。

1)在需要扩图的边缘，涂上不规则的蒙版，防止图像衔接处过于明显，此时要在layerunity中开启invert mask（默认已经开启）。

2)对不想改变的主体涂上蒙版，并且用比较不规则的蒙版边缘，此时要在在layerunity中关闭invert mask。

There are two ways to apply the mask (with the first option being the default):

1)Apply an irregular mask to the edges where the image needs to be extended, to prevent the image seams from being too noticeable. In this case, make sure to enable “invert mask” in LayerUnity (this is enabled by default).

2)Apply a mask to the subject you don’t want to change, using a more irregular mask edge. In this case, make sure to disable “invert mask” in LayerUnity.

2.参数 setting

1）x_percent y_percent

x_percent 增大，图像主体右移，反之左移。

y_percent 增大，图像主体上移，反之下移。

When x_percent increases, the main subject of the image shifts to the right, and vice versa to the left.

When y_percent increases, the main subject of the image moves upwards, and vice versa downwards.

2）expand

开启invert 的时候，expand设为-1

关闭invert 的时候，expand设为1

默认开启invert，expand为-1

When “invert” is enabled, set “expand” to -1.

When “invert” is disabled, set “expand” to 1.

By default, “invert” is enabled, and “expand” is set to -1.
