Edit regions and arrows without rebuilding the image
Use Canvas region control and an arrow to protect approved areas while selecting a narrow defect for a local edit.

Problem
Regenerating an entire image for one small defect can also change an approved face, product placement, or color relationship.
Outcome
You can keep the repair boundary small and compare before and after files for unintended changes.
Preparation
- Save the current result as a separate file and keep an undo point.
- Limit each edit pass to one defect and state the desired replacement.
- Note the preserved context, boundaries, and textures.
Decisions
- Selection size
- Include the defect plus only enough surrounding space for a natural blend.
- Arrow placement
- Place the arrow tip clearly inside the intended repair target.
- Instruction scope
- Separate what should change from what should remain using observable terms.
- Full regeneration
- Use full regeneration only when composition is wrong; otherwise preserve identity and product shape with a region edit.
Warnings
- Oversized region
- A broad selection can invite reinterpretation of nearby people, products, and structure.
- Visible seams
- Selections crossing hair, shadows, or patterns may leave inconsistent transitions.
- Stacked edits
- Several overlapping repairs make it harder to track changes to previously accepted areas.
Pre-publish checklist
- A pre-edit file and undo point are preserved.
- The selection stays close to one defect.
- The arrow identifies the desired replacement target.
- The instruction states the preserved context.
- A broad selection does not include nearby structure.
- Before and after files are compared at full and enlarged views.
- Identity and product shape remain consistent.
- Full regeneration is reserved for a composition failure.
AI disclosure
AI region editing can introduce errors beyond a selection or along its boundary, so a person should compare the before and after images.
