Picture Framing API

healthy 4,231 Subscribers

Picture-framing maths as an API, computed locally and deterministically — the mat-cutting and moulding numbers a framer or artist measures a job by. The mat endpoint sizes the mat board around an artwork: the window opening is the art minus a small overlap on each edge (≈ 0.25 inch so the mat holds the print), and the outer mat is the window plus the border widths — give one border or per-side borders, with a heavier bottom for a balanced, bottom-weighted mat, so an 8×10 print with a 2-inch border has a 7.5×9.5 window and an 11.5×13.5 mat. The moulding endpoint computes the frame stick needed: length = inner perimeter + 8 × the moulding width, because each of the four 45-degree mitred corners adds one moulding width — an 11.5×13.5 frame in 1.5-inch moulding needs 62.5 inches, plus any waste allowance. Everything is computed locally and deterministically, so it is instant and private. Ideal for picture-framing, custom-framing, art-gallery and DIY app developers, mat-cutter and moulding-estimating tools, and framing education. Pure local computation — no key, no third-party service, instant. Imperial inches in; lengths in inches and feet. Live, nothing stored. 2 compute endpoints. A planning aid — measure twice, cut once.

Lumber Calculator API

Lumber and framing material-estimation maths as an API, computed locally and deterministically. The boardfeet endpoint computes board feet — the standard volume unit for sawn timber, (thickness_in × width_in × length_ft) ÷ 12 — for a quantity of boards, with the total board feet and linear feet. The studs endpoint frames a wall: the number of vertical studs, ceil(wall length ÷ spacing) + 1 (16-inch ≈ 0.4064 m or 24-inch ≈ 0.6096 m centres), with two extra studs per opening, plus the plate boards for the top and bottom plates. The cost endpoint totals the lumber either by board foot (board feet × price per board foot) or by piece (pieces × price per piece). Everything is computed locally and deterministically, so it is instant and private. Ideal for construction, carpentry and DIY app developers, framing and material take-off tools, and lumberyard and builder calculators. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 endpoints. This is lumber and framing estimation; for drywall sheets use a drywall API and for concrete use a concrete API.

Equine Care API

Horse-care maths as an API, computed locally and deterministically — the everyday numbers a horse owner, barn manager or vet tech runs without reaching for a chart. The weight endpoint estimates body weight from a weight-tape measurement using the classic formula weight ≈ heart girth² × body length ÷ a type divisor (adult 330, yearling 301, weanling 280, pony 299) with measurements in inches — a horse with a 72-inch girth and 66-inch length comes out at about 1,037 lb (470 kg), the number you actually dose wormer and feed against. The feed endpoint turns body weight and a goal into daily forage: horses eat roughly 1.5–2.5 % of body weight in dry-matter forage a day, so a 1,000 lb horse on maintenance wants about 15–20 lb of hay, more to gain and less to slim. The gestation endpoint gives the foaling due date and the normal 320–362 day window from a breeding date — a mare bred on 1 April is due around 7 March the next year, give or take three weeks. Everything is computed locally and deterministically, so it is instant and private. Ideal for barn-management and horse-care apps, breeding and foaling trackers, feed-calculator and tack-shop sites, and equine-vet tools. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 compute endpoints. Educational estimates — not veterinary advice.

Darkroom API

Analog darkroom and film maths as an API, computed locally and deterministically — the three corrections that bite when you develop film and make prints by hand. The reciprocity endpoint corrects long exposures for reciprocity failure, where film loses sensitivity past about a second: corrected time = metered^p (Schwarzschild p ≈ 1.3 for many films, settable per datasheet), so a metered 10-second exposure really wants about 20 seconds, a full stop more, while anything under the threshold is left untouched. The printexposure endpoint adjusts enlarger exposure when you change print size — light spreads as you raise the head, so exposure is proportional to (magnification + 1)², where magnification is print size ÷ negative size: going from 2× to 4× magnification turns a 10-second exposure into 27.8 seconds, about 1.5 stops, ready for f-stop printing. The pushpull endpoint scales development time for pushing or pulling film by N stops — time = base × factor^stops, roughly +40 % per stop pushed — turning a 7-minute base into 13.7 minutes at +2 stops, or 5 minutes pulled a stop. Everything is computed locally and deterministically, so it is instant and private. Ideal for film-photography and darkroom apps, light-meter and timer companions, lab and workshop tools, and analog-photography sites. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 compute endpoints. For digital depth-of-field use a photography API; for lab molarity use a dilution API.
