Svalboard Keymap Image Maker

qmk-skim (Svalboard Keymap Image Maker)

A Python CLI tool for generating high-quality keymap layout images for the Svalboard keyboard.

Features

• Generate individual layer keymap images with layer indicator circles
• Generate overview images showing all layers with connector lines
• Interactive TUI configurator for editing configuration files
• System dependency checker (skim doctor)
• Support for multiple keymap formats:
  • Keybard (.kbi)
  • Vial (.vil)
  • QMK c2json (.json)
• Configurable colors, layer names, and appearance
• High-quality output in multiple formats:
  • Vector: SVG
  • Raster: PNG, JPEG, WEBP, AVIF
• Stdin support for piping keymap data in scripts

Installation

You can install qmk-skim using pip, pipx, or uv.

Using uv (Recommended)

uv tool install qmk-skim

Using pipx

pipx install qmk-skim

Using pip

pip install qmk-skim

Usage

The package installs the skim command-line tool, but if you prefer to use the tool without installing it, you can use uvx:

uvx --python 3.10 --from 'qmk-skim[cairo,playwright]' skim doctor

Check your environment

# Verify system dependencies (render engines, etc.)
skim doctor

Generate keymap images

# Generate all layers + overview from a keymap file
skim generate --keymap my-keymap.kbi --output-dir ./images

# Generate with custom configuration
skim generate --keymap my-keymap.kbi --config skim-config.yaml --output-dir ./images

# Generate specific layers only
skim generate --keymap my-keymap.kbi --layer 1 --layer 3-5 --layer overview

# Generate PNG output (requires Chromium or Cairo)
skim generate --keymap my-keymap.kbi --format png --output-dir ./images

# Read keymap from stdin
cat my-keymap.json | skim generate - --output-dir ./images

Configure appearance

# Launch the interactive TUI configurator
skim configure --interactive

# Edit an existing configuration file in the TUI
skim configure --interactive --config skim-config.yaml

# Generate a config from a Keybard keymap (extracts layer colors, names, custom keycodes)
skim configure --keymap my-keymap.kbi --output skim-config.yaml

# Import QMK named colors from color.h
skim configure --keymap my-keymap.kbi --qmk-color-header /path/to/color.h --output skim-config.yaml
