image-tools

A command-line toolkit for manipulating images with ImageMagick and converting raster images, such as PNGs and JPGs, into SVG vector files with vtracer.

In plain words
What is it for?
Use it to convert, resize, crop, or edit PNG and JPG files, remove watermarks, or trace simple and detailed raster images into SVG.
Why use it?
It provides repeatable terminal commands for common image changes and for turning suitable bitmap artwork into scalable vector artwork.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

image-tools scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 128 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Image Tools

CLI-first image manipulation using ImageMagick (raster) and vtracer (raster-to-vector).

Prerequisites

Check if installed

which magick && echo "imagemagick OK" || echo "need: brew install imagemagick" which vtracer && echo "vtracer OK" || echo "need: cargo install vtracer"

Install if missing: brew install imagemagick # raster image editing cargo install vtracer # raster-to-vector conversion (Rust)

Raster-to-SVG Conversion

Simple flat icon (single/few colors)

Best for logos, icons, flat illustrations:

vtracer --input input.png --output output.svg
--colormode color
--filter_speckle 10
--color_precision 4
--corner_threshold 60
--segment_length 6
--gradient_step 32

High-detail image

For complex images, increase precision:

vtracer --input input.png --output output.svg
--colormode color
--filter_speckle 4
--color_precision 6
--corner_threshold 60
--segment_length 4

Black-and-white / monochrome

For line art, text, or single-color designs:

vtracer --input input.png --output output.svg --colormode bw

Tuning guide

  • file too large → increase filter_speckle, gradient_step, decrease color_precision
  • too rough/blocky → decrease segment_length, filter_speckle
  • too many colors → decrease color_precision (1-8, lower = fewer colors)

Raster Editing with ImageMagick

Remove watermark / overlay

Paint over a region with a solid color (e.g. matching background):

Get image dimensions first

magick identify input.png

Paint rectangle over bottom-right corner (100x100 area)

magick input.png -fill "#0F0F0F" -draw "rectangle 1180,1180 1280,1280" output.png

Resize

Resize to specific width, maintain aspect ratio

magick input.png -resize 512x output.png

Resize to exact dimensions

magick input.png -resize 512x512! output.png

Resize to fit within bounds (no upscale)

magick input.png -resize 512x512> output.png

Crop

Crop to 500x500 from top-left

magick input.png -crop 500x500+0+0 output.png

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

image-tools is a skill published in the GitHub repository tta-lab/ttal-cli (23 stars, last pushed 1mo ago), licensed MIT. It adds 34 tokens to every session and 993 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
