Contrast icon: Pixel-to-Crochet Chart Converter

Inspect a narrow light break in a dark icon

The twelve-by-fourteen input is an original lighthouse-like silhouette with a widening tower, a broad base, a small roof and a light aperture. The design goal is preserving the narrow light break below the upper cap of a compact high-contrast mark. It is not a navigational drawing or a photograph of a particular building. All white areas, including the aperture, become worked background yarn.

Audit the two-color budget

The source contains forty-four dark pixels and 124 white pixels, totaling 168. Two white cells span the entire narrow tower at that source row, forming a light break rather than a fully enclosed window. They must remain white in the saved conversion. A correct dark total alone cannot prove that the aperture is in the right place: moving two other cells could preserve the count. Compare both the exact pixel coordinates and the lower broad base in the original PNG.

Watch small internal details when resizing

Begin at twelve columns, fourteen rows and two maximum colors. The native-resolution conversion avoids scaling and should retain every source region exactly. If you reduce the width or height, the aperture may become too small to survive raster resampling and quantization. That is a meaningful design change, not a reason to label the smaller result an identical copy. Save each trial separately and compare its light break with the source.

Represent white as solid fabric

The aperture is not an instruction to skip two stitches or make a chain opening. Work it with the white yarn in the listed sequence. The source image says nothing about hole construction, load-bearing edges or a separate tower outline. For a physical patch, choose smooth contrasting yarns and sample the two-cell light area before planning a large application. A fluffy dark yarn can obscure the opening without any error in the stored grid.

Questions and practical corrections

Why does the tower look solid?

Compare the two light aperture coordinates and actual yarn visibility. A resampled source or a missed color change can erase the gap.

Can I cut around the dark silhouette?

The construction is a complete rectangle. Cutting the background would not produce a checked crochet edge.

How do I find an upside-down import?

The broad base belongs near the bottom, while the small roof belongs above the tower. Check both landmarks before following the working rows.

Download the source and reproduce the conversion

Download the original PNG input. This code-drawn illustration is shown enlarged with crisp pixels below; it is not documentary photography.

In the Pixel-to-Crochet Chart Converter, set 12 columns, 14 rows and a maximum of 2 colors before choosing the PNG file. Conversion occurs locally. Use Reprocess source image after changing resolution or the color limit. The exact native source uses 2 output palette slots: yarn 1 #ffffff (124 stitches); yarn 2 #202e45 (44 stitches).

Download the exact converted project JSON for restoration and comparison. The saved grid uses the lower-left origin. Preserve it before trying another image or palette; a resized or reduced version is a separate design.

Work the actual counted fabric

Use compatible smooth yarns and a suitable trial hook. Chain 13 and work 12 US single crochets from the second chain. Later rows use one uncounted turning chain and alternate working direction. Change color on the final pull-through before the next yarn. In UK terminology these single crochets are double crochets. Follow every row below, then fasten off and weave ends. Measure a washed sample for physical dimensions and material consumption; the pixel budget excludes carries, tails, seams and any later border. See the chart-reading guide for matching the symbols to the written route.
