Resolution Multiply (JPS)

Documentation

• Class name: Resolution Multiply (JPS)
• Category: JPS Nodes/Math
• Output node: False

The Resolution Multiply node is designed to scale the dimensions of an image by a specified factor, effectively multiplying the width and height of the image by this factor to produce new dimensions. This node is useful in scenarios where image resolution adjustments are required, such as preparing images for processing or display at different sizes.

Input types

Required

• width
  • Specifies the original width of the image. The width is scaled by the factor to calculate the new width.
  • Comfy dtype: INT
  • Python dtype: int
• height
  • Specifies the original height of the image. The height is scaled by the factor to calculate the new height.
  • Comfy dtype: INT
  • Python dtype: int
• factor
  • The multiplier used to scale the width and height of the image. A factor greater than 1 increases the image size, while a factor less than 1 would decrease it (though the node's constraints do not allow for reduction).
  • Comfy dtype: INT
  • Python dtype: int

Output types

• width_resized
  • Comfy dtype: INT
  • The new width of the image after scaling by the specified factor.
  • Python dtype: int
• height_resized
  • Comfy dtype: INT
  • The new height of the image after scaling by the specified factor.
  • Python dtype: int

Usage tips

• Infra type: CPU
• Common nodes: unknown
