Convert DXF to PNG, JPG, or SVG for sharing (e.g. Telegram) or further editing.
Convert DXF (CAD) files to PNG, JPG, or SVG. Useful when you have DXF from map-grabber, Rhino, or other CAD tools and need a raster image to send in chat or a vector SVG for editing.
ezdxf (DXF read + drawing add-on)matplotlib (for PNG/JPG only)Pillow (for JPG only)Setup: OpenClaw does not install Python packages automatically. After installing this skill, run once: pip install -r requirements.txt (from the skill folder). If a script fails with ModuleNotFoundError, install the missing package.
Parameters:
input: Path to the DXF file.-o, --output: Output file path (default: same name as input with .png, .jpg, or .svg).-f, --format: png (default), jpg, or svg.--width, --height: Output size in pixels for PNG/JPG only (keeps aspect ratio if only one is set).--dpi: DPI for PNG/JPG (default 150).--margin: Margin in mm for SVG (default 2).# DXF to PNG (default)
python3 scripts/convert_dxf.py drawing.dxf -o drawing.png
# DXF to SVG (vector, no matplotlib for this path)
python3 scripts/convert_dxf.py site.dxf -f svg -o site.svg
# DXF to JPG
python3 scripts/convert_dxf.py site.dxf -f jpg -o site.jpg
# Fixed width 800px (height auto)
python3 scripts/convert_dxf.py map.dxf -o map.png --width 800
Used from the OpenClaw Telegram conversation. Run the script with -o <path>.png or -o <path>.jpg, then send that file to the user via the OpenClaw message/media tool.
OpenClaw allowed paths: The message tool only sends files from allowed dirs (~/.openclaw/media/, ~/.openclaw/agents/, or /tmp). Use e.g. -o ~/.openclaw/media/out.png or -o /tmp/out.png; do not use the skill install directory or sending will fail.
Agent behavior: When the user asks to convert a DXF to PNG, JPG, or SVG (or "send DXF as image"), run the script directly with exec: use convert_dxf.py <dxf_path> -o <output> with -f png/jpg/svg and output path under an allowed dir; then send the generated file. Do not ask for confirmation; execute and return the file.
User: "Convert this DXF to PNG so I can send it in Telegram."
Action: Run convert_dxf.py <path> -o /tmp/out.png, then send the PNG to the user.
User: "Export the DXF as SVG."
Action: Run convert_dxf.py <path> -f svg -o /tmp/out.svg, then send or return the SVG path.
User: "Turn the site DXF into a JPG, 1200px wide."
Action: Run with -f jpg -o /tmp/site.jpg --width 1200, then send the JPG.
