Patch Apply

What is it for?

• Applying a patch to the final image
• Returning the result of patch ON/OFF control or merging to an image
• Keeping generation and manual correction in separate nodes

Overview

An application node that applies a patch (correction difference) to an image. The patch family separates responsibilities: edit with pixel_patch, control with patch_toggle / patch_merge, then return the result to the artwork with this endpoint.

Usage tips

• The go-to setup is image + patch (from pixel_patch or a merge) → patch_apply. An unconnected patch passes the image through, so placing the node early is safe.
• Dimension mismatches are errors. Keep the patch target dimensions equal to the destination image.

Related nodes

• pixel_patch — edits the patch
• patch_merge / patch_toggle — combines or toggles patches before application
• image_manual_diff — creates a patch from an external correction

Notes

• If patch is unconnected, image passes through unchanged.
• A mismatch between the patch target dimensions and image dimensions produces a node error.
• Keep responsibility for returning the patch to an image here, while retaining editing state in PixelPatch.

Examples

1. Noise Generate -> PatchApply
   • Prepare a place to connect a patch later downstream.
2. Pixel Patch.patch -> PatchApply
   • Apply only the manual correction as a separate node.
3. PatchMerge -> PatchApply
   • Combine several patches, then apply them once.
