Patch Merge

What is it for?

• Keeping patches separate by purpose and combining them later
• Layering an additional correction over a base correction
• Gathering multiple PixelPatch values into one

Overview

Combines two patches into one. At overlapping coordinates, the overlay input takes priority. Merge patches separated by purpose, such as outline corrections and color corrections, before applying them.

Usage tips

• A clean structure is to edit patches by purpose, merge them at the end, then connect to patch_apply. Place patch_toggle on individual branches to toggle each correction separately.
• This also merges an automatic difference from image_manual_diff with a hand-drawn pixel_patch.

Related nodes

• pixel_patch / image_manual_diff — supply patches to combine
• patch_apply — applies the combined patch
• patch_toggle — toggles individual patches

Notes

• When both patches write the same coordinate, overlay wins.
• If both patches include target dimensions, their dimensions must match.
• If only one input is connected, it passes through unchanged.

Examples

1. Pixel Patch A.patch + Pixel Patch B.patch -> PatchMerge -> PatchApply
   • Edit manual corrections separately, then combine them.
2. ImageManualDiff.patch + Pixel Patch.patch -> PatchMerge
   • Merge an automatically extracted difference with a hand-drawn patch.
