# Documentation
- Class name: MakeImageBatch
- Category: ImpactPack/Util
- Output node: False
- Repo Ref: https://github.com/ltdrdata/ComfyUI-Impact-Pack.git
‘MakeImageBatch’节点旨在高效地将多个图像组合成一个单一的批次以供进一步处理。它通过在必要时调整大小以确保批次中的所有图像具有相同的尺寸,并将它们沿批次维度连接起来。该节点在准备图像处理任务的统一数据集方面发挥着关键作用,例如批量神经网络训练或批量图像操作。
# Input types
## Required
- image1
- ‘image1’参数是用作图像批次尺寸参考的第一个图像。它至关重要,因为如果后续图像的尺寸不同,它们将被调整以匹配其尺寸。节点的功能依赖于此参数来创建用于下游任务的统一批次。
- Comfy dtype: IMAGE
- Python dtype: torch.Tensor
## Optional
- kwargs
- ‘kwargs’参数允许在批次中包含额外的图像。通过此参数提供的每个图像都以与‘image1’相同的方式进行处理,确保批次的一致性。‘kwargs’的灵活性使节点能够适应不同场景中的可变数量的图像,增强了其实用性。
- Comfy dtype: COMBO[str, IMAGE]
- Python dtype: Dict[str, torch.Tensor]
# Output types
- image_batch
- ‘image_batch’输出是已连接的图像批次,这些图像已被调整大小以保持批次内的一致性。这个输出很重要,因为它为后续的图像处理任务奠定了基础,确保批次准备好进行如神经网络输入或批量图像编辑等操作。
- Comfy dtype: IMAGE
- Python dtype: torch.Tensor
# Usage tips
- Infra type: CPU
