Documentation

  • Class name: Inference_Core_InpaintPreprocessor
  • Category: ControlNet Preprocessors/others
  • Output node: False

Inpaint Preprocessor节点专为图像修复任务中的预处理而设计。它通过应用蒙版来标识需要修复的区域,有效地将被蒙蔽的像素设置为特定值,为后续处理做好准备。

Input types

Required

  • image
    • image参数代表要进行预处理的输入图像,是蒙版应用的主要数据对象。
    • Comfy dtype: IMAGE
    • Python dtype: torch.Tensor
  • mask
    • mask参数指定输入图像中需要进行修复的区域,标识哪些像素应该被考虑修改。
    • Comfy dtype: MASK
    • Python dtype: torch.Tensor

Output types

  • image
    • 输出是一个经过预处理的图像,其中指定区域已被蒙蔽,为后续处理步骤做好了准备。
    • Comfy dtype: IMAGE
    • Python dtype: torch.Tensor

Usage tips

  • Infra type: GPU
  • Common nodes: unknown

        mask = mask.movedim(1,-1).expand((-1,-1,-1,3))
        image = image.clone()
        image[mask > 0.5] = -1.0  # set as masked pixel
