What is contourify?

contourify is a Python library that combines AI object detection with interactive SVG generation. Upload any image, detect the objects inside it, pick one, attach a description and a link — and get back a single self-contained .svg file that works in any browser with no external dependencies.

photo.jpg  →  contourify  →  photo_contourify.svg

The output SVG:

• Embeds the original image
• Draws an animated contour around the selected object
• Shows a styled popup card on hover with your description
• Contains a clickable Visit Link button
• Works anywhere SVG is supported — browsers, email, Discord, LinkedIn

Installation

pip install contourify

Quick Start

Python API

from contourify import Contourify
 
ct = Contourify()
 
# Step 1 — detect objects
objects = ct.detect("photo.jpg")
for obj in objects:
    print(f"{obj.id}: {obj.label} ({obj.score_pct})")
 
# Step 2 — generate interactive SVG
svg = ct.generate(
    image_path="photo.jpg",
    object_id=0,
    text="Handcrafted Oak Chair — Free shipping worldwide",
    link="https://shop.example.com/chair",
    color="#3b82f6",
)
 
# Step 3 — save to file
with open("chair_interactive.svg", "w", encoding="utf-8") as f:
    f.write(svg)

One-call API

from contourify import Contourify
 
ct = Contourify()
 
objects, svg = ct.detect_and_generate(
    image_path="photo.jpg",
    object_id=0,
    text="Sony A7 Camera",
    link="https://shop.example.com/camera",
    color="#27c97a",
)
 
with open("camera_interactive.svg", "w", encoding="utf-8") as f:
    f.write(svg)

CLI

# Detect all objects in an image
contourify detect photo.jpg
 
# Output example:
#   Found 3 object(s):
#
#   ID     Label                Confidence
#   ──────  ────────────────────  ────────────
#   0       Chair                91%
#   1       Laptop               85%
#   2       Cup                  63%
#
#   Use the ID above with the generate command:
#   contourify generate photo.jpg --object <ID> --text "..." --link https://...
 
# Generate interactive SVG
contourify generate photo.jpg \
    --object 0 \
    --text "Handcrafted Oak Chair" \
    --link "https://shop.example.com/chair"
 
# With custom color and output path
contourify generate photo.jpg \
    --object 1 \
    --text "Sony A7 Camera" \
    --link "https://shop.example.com/camera" \
    --color "#27c97a" \
    --output camera_hotspot.svg

Image Quality Requirements

contourify validates images before processing to ensure accurate detection:

Requirement	Minimum
File size	20 KB
Resolution	300 × 300 px
Sharpness	Clear, well-focused

Images that are too small, too low resolution, or blurry will be rejected with a clear error message explaining what to fix.

---

Model Options

By default contourify uses yolov8n-seg (nano — fastest). For better accuracy on complex images use a larger model:

# More accurate — slower
ct = Contourify(model="yolov8s-seg.pt")  # small
ct = Contourify(model="yolov8m-seg.pt")  # medium
ct = Contourify(model="yolov8l-seg.pt")  # large

The model is downloaded automatically on first use (~6 MB for nano).

---

Telemetry

contourify collects anonymous usage data to help improve the library. You are asked once on first run. You can manage this at any time:

contourify --telemetry status   # check current setting
contourify --telemetry off      # disable
contourify --telemetry on       # enable

Or programmatically:

from contourify.telemetry.tracker import disable_telemetry
disable_telemetry()

What is collected (with consent):

• Event type (detect, generate, cli_run)

• Platform and Python version

• Approximate country (from ipinfo.io) What is never collected:

• Image paths or contents

• SVG output

• Any personally identifying information Config stored at: ~/.contourify/config.json

API Reference

Contourify(model="yolov8n-seg.pt")

Main class. Initialise once and reuse.

.detect(image_path, conf=0.25, imgsz=640) → List[DetectedObject]

Detect all objects in an image. Returns list sorted by confidence descending.

.generate(image_path, object_id, text, link, color="#3b82f6") → str

Generate interactive SVG for a detected object. Returns SVG string.

.detect_and_generate(image_path, object_id, text, link, color) → tuple

Convenience method — detect and generate in one call. Returns (objects, svg_string).

DetectedObject

Attribute	Type	Description
id	int	Zero-based object index
label	str	COCO class label e.g. "chair"
score	float	Confidence 0–1
score_pct	str	Confidence as string e.g. "91%"
bbox	BBox	Normalised bounding box
contour	list	Normalised contour points
width	int	Image width in pixels
height	int	Image height in pixels
