Horizontal joins: pixel-level A/B needs a shared zoom baseline and a shared horizontal reference line
`horizontal-panorama-join` backs design diffs, spreadsheet revisions, and marketing compares. Unequal scaling fakes size changes; vertical misalignment makes table rows appear edited. Ultra-wide exports shrink to illegibility inside wikis. Caption v1/v2 with dates and add a thin gray ramp to reduce monitor color arguments.
`horizontal-panorama-join`: align critical horizontals before merging, then caption versions with one template
- Pick a baseline panel—usually old-left, new-right—draw guides on table tops or horizons, then scale the partner panel until structures lock. Avoid hand-drag scaling; use numeric percentages when needed.
- Insert neutral gutter plus a vertical rule so color domains do not visually fuse; confirm legends and axis titles are not clipped. Plan separate 1:1 detail crops when the canvas exceeds wiki preview limits.
- Filename encodes topic and date; for external use archive untouched singles alongside the merge. Write decisions in the doc body, not only “obvious from the picture.”
Horizontal merge FAQ: fake deltas, monitor color fights, wiki shrink, four-up chaos
Design swears the button grew—engineering says scale drift. One image to settle it?
Align with identical zoom and a shared anchor (nav bottom edge), overlay a faint grid, and optionally publish a difference matte—eyeball scaling is never enough for side-by-side review.
Left/right color mismatch across monitors—does the merger own that?
No—note sRGB, disable night modes for review, embed a gray ramp and brand swatch, and if needed convene on one calibrated display.
Eight-thousand-pixel canvas becomes mush inside Confluence—how to deliver both whole and readable?
Ship a moderated-width overview plus tight 1:1 crops, or link the original asset. Do not expect wiki engines to magically preserve ultra-wide detail.
Four variants in one row confuses everyone—layout fix?
Use two-up panels across two exports, or group pairs with bold “Round 1/2” headers. Keep color cues on separators, not full-bleed backgrounds that die in grayscale print.
Marketing cropped the “before” tighter to exaggerate improvement—legal exposure?
Likely misleading comparative advertising; retain equal field-of-view masters and caption any crop or grade. Run external assets through legal review—layout tools do not confer honesty.
