# Documentation
|
|
- Class name: RemapPinch
|
|
- Category: Bmad/CV/Transform
|
|
- Output node: False
|
|
|
|
RemapPinch节点用于对图像应用挤压变形效果，允许围绕指定的中心点以不同程度的强度操纵图像几何形状。
|
|
|
|
# Input types
|
|
## Required
|
|
- power_x
|
|
- 指定要应用的水平挤压效果的程度。较高的值会产生更明显的挤压效果。
|
|
- Comfy dtype: FLOAT
|
|
- Python dtype: float
|
|
- power_y
|
|
- 指定要应用的垂直挤压效果的程度。较高的值会产生更明显的挤压效果。
|
|
- Comfy dtype: FLOAT
|
|
- Python dtype: float
|
|
- center_x
|
|
- 确定应用挤压效果的水平中心。取值范围从0到1，代表图像的宽度。
|
|
- Comfy dtype: FLOAT
|
|
- Python dtype: float
|
|
- center_y
|
|
- 确定应用挤压效果的垂直中心。取值范围从0到1，代表图像的高度。
|
|
- Comfy dtype: FLOAT
|
|
- Python dtype: float
|
|
|
|
# Output types
|
|
- remap
|
|
- 该节点返回一个remap输出，用于将指定的挤压变形效果应用到图像上。
|
|
- Comfy dtype: REMAP
|
|
- Python dtype: Tuple[np.ndarray, np.ndarray, NoneType]
|
|
|
