Turn a small pixel motif into a counted stitch chart

# An exact, symbol-coded sprout chart

This illustrative chart preserves the original 12 × 12 potted-sprout grid. Rows run downward, columns run rightward and the top-left cell is row 1, column 1. Each marked cell represents one full cross. G uses a circle, T a diagonal cross and P an upright triangle. The dot in the source becomes a visibly blank, unstitched cell.

## Checked cell totals

- G / circle: 26 marked cells
- T / cross: 4 marked cells
- P / triangle: 16 marked cells
- . / blank: 98 unstitched cells
- Total: 144 cells, including 46 marked cells

These are cell counts, not thread-length or purchasing estimates. G, T and P are arbitrary color IDs; no manufacturer SKU is assigned.

## What the downloads contain

The primary color SVG and supporting grayscale SVG are editable, self-contained vector charts. Their actual PNG exports are each 1200 × 1440 digital pixels. Both have distinct geometric symbols, row/column numbers, a top-left orientation note and a complete drawn legend and tally. Pixel dimensions describe the image canvas; they do not establish a physical craft size or a paper setting.

The source grid, complete source brief and structured input contract stand apart from the generated answer. The cell CSV accounts for every coordinate, including blank cells, using row, column, code, symbol and stitched fields. The tally CSV lists all four legend codes. The source grid and CSV also provide a text-based way to inspect the chart’s contents.

## What was actually checked

On 14 October 2026, a read-only local checker independently counted the exact grid, compared it with separately transcribed occupied-coordinate ranges and per-row counts, and round-tripped all 144 CSV records back to the unchanged source. It checked each cell’s actual SVG primitives, position, fill and symbol in both SVGs, plus numbering, orientation, all legend symbols and totals. Eighteen deliberate mutations were rejected, including an 11-cell row, an unknown code, changed data and tallies, rotated orientation, moved or altered symbols and a same-tally cell swap.

The actual color and grayscale PNG exports were rendered with installed Inkscape 1.4 and opened with view_image at readable size. Symbols, counts, numbering and footnotes were visible and uncut. A pixel check found zero non-gray pixels in the grayscale export. No physical printed proof or stitched sample was made.

To repeat the fixture checks, download the ten core files named by the checker into one folder: the source TXT/JSON/brief, two CSVs, two SVGs, two PNGs and the checker itself. Inspect sprout-checker.py, then run “python3 -I sprout-checker.py”. It reads its named sibling files and prints a fresh dated report without changing them. The report and visual-review files record this edition’s checks and exact hashes. The checker deliberately rejects a changed motif; adaptation requires a new, independently reviewed source reference rather than weakening checks to make an answer pass.

## Before making it

Choose actual thread and fabric yourself. Print a proof using your chosen paper settings, confirm that every symbol and number remains readable, and check the final rendering against the source again. A real stitched sample is needed before calling it craft-tested. Local cell and image checks do not determine floss length, fabric suitability, finished physical size or physical stitchability. They do not establish consumer AI execution, account-plan access, browser compatibility or accessibility compliance. Time savings are unmeasured.
