Switch (SEGS/legacy)

Documentation

• Class name: SEGSSwitch
• Category: ImpactPack/Util
• Output node: False

The SEGSSwitch node dynamically selects between multiple segmentation (SEGS) inputs based on a specified index. It facilitates conditional processing paths within a pipeline, allowing for the flexible use of different segmentation data.

Input types

Required

• select
  • Specifies the index of the segmentation input to select. This index determines which segmentation data is used for processing, enabling dynamic choice based on conditions or preferences.
  • Comfy dtype: INT
  • Python dtype: int
• sel_mode
  • unknown
  • Comfy dtype: BOOLEAN
  • Python dtype: unknown

Optional

• input1
  • unknown
  • Comfy dtype: *
  • Python dtype: unknown

Output types

• selected_value
  • Comfy dtype: *
  • unknown
  • Python dtype: unknown
• selected_label
  • Comfy dtype: STRING
  • unknown
  • Python dtype: unknown
• selected_index
  • Comfy dtype: INT
  • unknown
  • Python dtype: unknown

Usage tips

• Infra type: CPU
• Common nodes: unknown
