Read from the package source without running it. The installed server may list more.

  • centerline

    Trace line art to single-stroke centreline SVG (for plotters, lasers, CNC). Optionally emit G-code with tool=laser|pen.

  • component

    Turn an SVG into a React, Vue, Svelte or Solid component, ready to import. Emits typed TSX for React

  • convert

    Convert between formats by extension. Supports raster↔SVG plus vector export to .dxf/.eps/.pdf (CAD/CNC/print).

  • crop

    Content-aware crop to an aspect ratio, keeping the salient subject (edges + saturation) rather than the centre. aspect like "1:1", "16:9", "4:5".

  • diff

    Perceptual visual-regression diff. Paints a CIEDE2000 heatmap of what changed between two images (raster or SVG) and reports changed-pixel count/fraction, max & mean ΔE, and SSIM. Give an output path to save the heatmap.

  • doc_to_images

    Render a document (PDF, SVG, or Office docx/xlsx/pptx) to one image per page. PDF needs the optional mupdf package; Office needs local LibreOffice.

  • extract

    Recover the original bitmap from an SVG written by embed/lossless mode, and verify it byte for byte.

  • image_info

    Inspect an image without converting it: dimensions, format, colour space, alpha, distinct colour

  • images_to_pdf

    Combine images into one multi-page PDF (one image per page).

  • measure

    Measure how close two images (raster or SVG) are: PSNR, SSIM, mean CIEDE2000, and whether they are pixel-identical.

  • office_convert

    Convert an Office document ⇄ PDF (and between Office formats) via local LibreOffice. Target format is the output file extension.

  • optimize

    Minify an SVG without changing what it draws: round coordinates, drop default attributes, strip the

  • palette

    Extract a perceptual dominant-colour palette (hex + weight) from an image.

  • placeholder

    Generate a BlurHash string for lazy-loading a raster image.

  • rasterize

    Render an SVG to a raster image (PNG/JPEG/WebP/AVIF/TIFF). The inverse of vectorize, and the

What the publisher says

Vecline

Measurable raster ⇄ SVG conversion — and a broad image + document toolkit. Ten raster formats, every one convertible to every other, with the accuracy of every conversion actually measured rather than asserted; plus PDF & Office (docx/xlsx/pptx) rendering and conversion, images → PDF, DXF at a real physical cut size alongside EPS and G-code for makers, centerline tracing and content-aware crop — most of it in a zero-dependency core that is CI-proven to bundle for a browser.

On flat artwork — logos, icons, UI, screenshots, pixel art — the output is bit-exact: SSIM 1.0000, PSNR ∞, zero differing pixels, and on a real logo smaller than imagetracerjs or vtracer manage while still only approximating — 24 KB against their 60 and 64. That comes from recognising the image is cheaper to encode exactly than to approximate, not from a better curve fit. Tracing now emits real curves by default — sub-pixel edge placement is on, which is the only thing that lets the curve fitter run at all; before this the default returned a staircase with zero curve commands on real artwork. It costs about 2.35x the gzipped bytes, because moving coordinates off the integer lattice costs compression, and --no-subpixel buys the old smaller output back. Pixel and exact modes are untouched and stay bit-exact. potrace is smaller than everyone and much less accurate, which is a real trade and not one this README will hide. On real photographs it leads all three on SSIM by 0.05–0.18 at their default settings; one documented vtracer flag closes part of that. It is not the fastest — imagetracerjs is quicker on every fixture measured. Every number in this README is reproducible: node scripts/fetch-corpus.mjs && npm run compare. (The corpus is fetched rather than committed — the photographs are not ours to redistribute.)

▶ Vecline Studio — vecline.xyz — the whole toolkit in your browser. Drop an image, a PDF, or a TGA/PNM/ICO no browser can read; tune it; watch live SSIM / PSNR / CIEDE2000; export SVG, DXF at a real cut size, EPS, PDF, G-code, React/Vue/Svelte/Solid components, colour separations, sprite sheets, favicons, BlurHash, or just re-encode between ten raster formats. Free, unlimited, no signup, works offline, and nothing is uploaded — every conversion runs in your tab, not on a server. (How it compares · dev playground)

vecline vectorize anything.png --lossless

--lossless returns a bit-exact SVG or it fails. It never silently gives you a near-miss.
