|
- Class name: LayerImageTransform
|
|
- Category: 😺dzNodes/LayerUtility
|
|
- Output node: False
|
|
- Repo Ref: https://github.com/chflame163/ComfyUI_LayerStyle
|
|
|
|
这个节点用于单独对layer_image进行变换，可改变大小，旋转，改变长宽比以及镜像翻转。

# Input types
|
|
|
|
## Required
|
|
|
|
- image
|
|
- 图片。
|
|
- Comfy dtype: IMAGE
|
|
- Python dtype: torch.Tensor
|
|
|
|
- x
|
|
- 坐标x值。
|
|
- Comfy dtype: INT
|
|
- Python dtype: int
|
|
|
|
- y
|
|
- 坐标y值。
|
|
- Comfy dtype: INT
|
|
- Python dtype: int
|
|
|
|
- mirror
|
|
- 镜像翻转。提供2种翻转模式, 水平翻转和垂直翻转。
|
|
- Comfy dtype: STRING_ONEOF
|
|
- Python dtype: str
|
|
- Options:
|
|
- None
|
|
- horizontal
|
|
- vertical
|
|
|
|
- scale
|
|
- 图层放大倍数，1.0 表示原大。
|
|
- Comfy dtype: FLOAT
|
|
- Python dtype: float
|
|
|
|
- aspect_ratio
|
|
- 图层长宽比。1.0 是原始比例，大于此值表示拉长，小于此值表示压扁。
|
|
- Comfy dtype: FLOAT
|
|
- Python dtype: float
|
|
|
|
- rotate
|
|
- 图层旋转度数。
|
|
- Comfy dtype: FLOAT
|
|
- Python dtype: float
|
|
|
|
- transform_method
|
|
- 用于图层放大和旋转的采样方法，包括lanczos、bicubic、hamming、bilinear、box和nearest。不同的采样方法会影响合成的画质和画面处理时间。
|
|
- Comfy dtype: STRING_ONEOF
|
|
- Python dtype: str
|
|
- Options:
|
|
- lanczos
|
|
- bicubic
|
|
- hamming
|
|
- bilinear
|
|
- box
|
|
- nearest
|
|
|
|
- anti_aliasing
|
|
- 抗锯齿，范围从0-16，数值越大，锯齿越不明显。过高的数值将显著降低节点的处理速度。
|
|
- Comfy dtype: INT
|
|
- Python dtype: int
|
|
