FlipImage

What is it?

The FlipImage node flips images horizontally, vertically, or in both directions. It's perfect for creating mirror effects, correcting orientation issues, or creating symmetrical compositions from existing images.

When would I use it?

Use this node when you want to:

  • Create mirror effects or reflections
  • Correct images that are oriented incorrectly
  • Create symmetrical compositions
  • Generate variations of existing images
  • Flip images for artistic or design purposes
  • Create left/right or up/down variations of the same image

How to use it

Basic Setup

  1. Add the FlipImage node to your workflow
  2. Connect an image source to the "input_image" input
  3. Choose your flip direction
  4. The flipped image will be available at the "output" parameter

Parameters

Flip Settings

  • direction: The direction to flip the image
    • horizontal: Flip left to right (mirror effect)
    • vertical: Flip top to bottom (upside down)
    • both: Flip both horizontally and vertically (180° rotation)

Outputs

  • output: The flipped image
  • was_successful: Indicates whether the flip operation succeeded
  • result_details: Detailed information about the flip operation

Example

A typical flipping workflow:

  1. Load an image using LoadImage

  2. Connect that image to the FlipImage node's "input_image" parameter

  3. Set the flip direction:

    • Select "horizontal" to create a mirror image
    • Select "vertical" to flip upside down
    • Select "both" to rotate 180 degrees

  4. Connect the "output" to DisplayImage to view the result

Important Notes

  • Live Preview: Changes are applied in real-time as you adjust parameters
  • Format Preservation: The node preserves the original image format and quality
  • RGBA Support: The node preserves transparency in RGBA images
  • Success/Failure Tracking: The node provides detailed status information about the operation

Common Issues

  • No Output: Check that your image source is properly connected to the "input_image" parameter
  • Unexpected Results: Remember that "horizontal" flips left-to-right, "vertical" flips top-to-bottom
  • Both Direction: "both" applies both horizontal and vertical flips, effectively rotating the image 180 degrees

Technical Details

The node uses PIL's image operations:

  • Horizontal Flip: Uses ImageOps.mirror() for left-to-right flipping
  • Vertical Flip: Uses ImageOps.flip() for top-to-bottom flipping
  • Both Directions: Applies both operations sequentially

This provides reliable image flipping capabilities with proper error handling and status reporting.
