# Documentation
|
|
- Class name: ImageEffectsNegative
|
|
- Category: image/effects
|
|
- Output node: False
|
|
|
|
ImageEffectsNegative节点通过反转颜色将图像转换为负片效果。这种效果是通过将每个颜色通道的值从最大可能值中减去来实现的，从而有效地反转了色谱，创造出一种摄影底片的效果。

# Input types
|
|
## Required
|
|
- images
|
|
- 需要转换为负片形式的输入图像。这个参数对节点的操作至关重要，因为它直接影响效果的视觉呈现。
|
|
- Comfy dtype: IMAGE
|
|
- Python dtype: torch.Tensor
|
|
|
|
# Output types
|
|
- image
|
|
- 转换后的负片形式图像，每个颜色通道的值都被反转，产生摄影底片效果。
|
|
- Comfy dtype: IMAGE
|
|
- Python dtype: torch.Tensor
