|
- Class name: ImageTransformPaddingAbsolute
|
|
- Category: image/transform
|
|
- Output node: False
|
|
|
|
ImageTransformPaddingAbsolute节点用于对一批图像应用绝对填充,允许向每个图像的高度和宽度添加指定数量的像素。可以从预定义的选项中选择填充方法,以控制如何填充新增的空间。
|
|
|
|
# Input types
|
|
## Required
|
|
- images
|
|
- 需要应用填充的图像批次。这是转换过程的主要输入。
|
|
- Comfy dtype: IMAGE
|
|
- Python dtype: List[torch.Tensor]
|
|
- add_width
|
|
- 要添加到每个图像宽度的像素数。
|
|
- Comfy dtype: INT
|
|
- Python dtype: int
|
|
- add_height
|
|
- 要添加到每个图像高度的像素数。
|
|
- Comfy dtype: INT
|
|
- Python dtype: int
|
|
- method
|
|
- 用于填充新增区域的方法,选项包括'reflect'(反射)、'edge'(边缘)和'constant'(常量)。
|
|
- Comfy dtype: COMBO[STRING]
|
|
- Python dtype: str
|
|
|
|
# Output types
|
|
- image
|
|
- 应用填充后的图像批次,根据指定的add_width和add_height增加了尺寸。
|
|
- Comfy dtype: IMAGE
|
|
- Python dtype: torch.Tensor
|
|
|
|
|
