ImageSize (Side)

Documentation

• Class name: easy imageSizeBySide
• Category: EasyUse/Image
• Output node: True

This node calculates the dimension of an image based on the specified side (longest or shortest), providing a simple way to obtain image resolution metrics.

Input types

Required

• image
  • The image for which the dimension is to be calculated, affecting the output by determining the longest or shortest side based on the image's width and height.
  • Comfy dtype: IMAGE
  • Python dtype: torch.Tensor
• side
  • Specifies whether to calculate the dimension based on the longest or shortest side of the image, directly influencing the result by selecting the appropriate dimension.
  • Comfy dtype: COMBO[STRING]
  • Python dtype: str

Output types

• resolution
  • Comfy dtype: INT
  • The calculated dimension (width or height) of the specified side (longest or shortest) of the image.
  • Python dtype: int
• ui
  • Displays the calculated dimension of the specified side of the image.

Usage tips

• Infra type: CPU
• Common nodes: unknown
