Invert Image

Documentation

Class name: ImageInvert
Category: image
Output node: False

The ImageInvert node is designed to invert the colors of an image, effectively transforming each pixel's color value to its complementary color on the color wheel. This operation is useful for creating negative images or for visual effects that require color inversion.

Input types

Required

image
- The 'image' parameter represents the input image to be inverted. It is crucial for specifying the target image whose colors are to be inverted, affecting the node's execution and the visual outcome of the inversion process.
- Comfy dtype: IMAGE
- Python dtype: torch.Tensor

Output types

image
- Comfy dtype: IMAGE
- The output is an inverted version of the input image, with each pixel's color value transformed to its complementary color.
- Python dtype: torch.Tensor

Usage tips

Infra type: GPU
Common nodes:
- PreviewImage
- ImageScale
- ImageCompositeMasked
- Reroute
- ArithmeticBlend

Source code

class ImageInvert:

    @classmethod
    def INPUT_TYPES(s):
        return {"required": { "image": ("IMAGE",)}}

    RETURN_TYPES = ("IMAGE",)
    FUNCTION = "invert"

    CATEGORY = "image"

    def invert(self, image):
        s = 1.0 - image
        return (s,)
