• Class name: SDXLAspectRatioSelector
• Category: Art Venture/Utils
• Output node: False

SDXLAspectRatioSelector节点的设计目的是选择和调整图像的宽高比，确保图像符合特定尺寸的同时保持原始比例。它提供了一种机制，可以将图像缩放到一系列预定义的宽高比，适用于各种显示或处理需求。

Input types

Required

• aspect_ratio
  • 从预定义的比例列表中指定图像所需的宽高比。这个选择决定了图像将被缩放到的尺寸，从而影响其最终外观。
  • Comfy dtype: COMBO[STRING]
  • Python dtype: str

Output types

• ratio
  • 选定的宽高比，以字符串形式表示，指示图像的宽度与高度之间的比例。
  • Comfy dtype: STRING
  • Python dtype: str
• width
  • 根据所选宽高比缩放后计算得出的图像宽度。
  • Comfy dtype: INT
  • Python dtype: int
• height
  • 根据所选宽高比缩放后计算得出的图像高度。
  • Comfy dtype: INT
  • Python dtype: int

Usage tips

• Infra type: CPU
• Common nodes: unknown
