LibreOffice Draw

Overview

LibreOffice Draw skill for creating, editing, converting, and automating vector graphics and diagram workflows using the native ODG (OpenDocument Drawing) format.

When to Use This Skill

Use this skill when:

• Creating vector graphics and diagrams in ODG format
• Converting between ODG, SVG, PDF, PNG formats
• Automating diagram and flowchart generation
• Creating technical drawings and schematics
• Batch processing graphics operations

Core Capabilities

1. Graphics Creation

• Create new ODG drawings from scratch
• Generate diagrams from templates
• Create flowcharts and org charts
• Design technical drawings

2. Format Conversion

• ODG to other formats: SVG, PDF, PNG, JPG
• Other formats to ODG: SVG, PDF
• Batch conversion of multiple files

3. Diagram Automation

• Template-based diagram generation
• Automated flowchart creation
• Dynamic shape generation
• Batch diagram production

4. Graphics Manipulation

• Shape creation and manipulation
• Path and bezier curve editing
• Layer management
• Text and label insertion

5. Integration

• Command-line automation via soffice
• Python scripting with UNO
• Integration with workflow tools

Workflows

Creating a New Drawing

Method 1: Command-Line

soffice --draw template.odg

Method 2: Python with UNO

import uno

def create_drawing():
    local_ctx = uno.getComponentContext()
    resolver = local_ctx.ServiceManager.createInstanceWithContext(
        "com.sun.star.bridge.UnoUrlResolver", local_ctx
    )
    ctx = resolver.resolve(
        "uno:socket,host=127.0.0.1,port=8100;urp;StarOffice.ComponentContext"
    )
    smgr = ctx.ServiceManager
    desktop = smgr.createInstanceWithContext("com.sun.star.frame.Desktop", ctx)
    doc = desktop.loadComponentFromURL("private:factory/sdraw", "_blank", 0, ())
    page = doc.getDrawPages().getByIndex(0)
    doc.storeToURL("file:///path/to/drawing.odg", ())
    doc.close(True)

Converting Drawings

# ODG to SVG
soffice --headless --convert-to svg drawing.odg

# ODG to PDF
soffice --headless --convert-to pdf drawing.odg

# ODG to PNG
soffice --headless --convert-to png:draw_png_Export drawing.odg

# SVG to ODG
soffice --headless --convert-to odg drawing.svg

# Batch convert
for file in *.odg; do
    soffice --headless --convert-to pdf "$file"
done

Format Conversion Reference

Supported Input Formats

• ODG (native), SVG, PDF

Supported Output Formats

• ODG, SVG, PDF, PNG, JPG, GIF, BMP, WMF, EMF

Command-Line Reference

soffice --headless
soffice --headless --convert-to <format> <file>
soffice --draw  # Draw

Python Libraries

pip install ezodf     # ODF handling
pip install odfpy     # ODF manipulation
pip install svgwrite  # SVG generation

Best Practices

1. Use layers for organization
2. Create templates for recurring diagrams
3. Use vector formats for scalability
4. Name objects for easy reference
5. Store ODG source files in version control
6. Test conversions thoroughly
7. Export to SVG for web use

Troubleshooting

Cannot open socket

# Inspect the listener and stop only the task-owned process after saving its documents.
soffice --headless --accept="socket,host=127.0.0.1,port=8100;urp;"

Quality Issues in PNG Export

soffice --headless --convert-to 'png:draw_png_Export:{"PixelWidth":{"type":"long","value":"2048"},"PixelHeight":{"type":"long","value":"2048"}}' drawing.odg

Limitations

• Use this skill only when the task clearly matches the scope described above.
• Do not treat the output as a substitute for environment-specific validation, testing, or expert review.
• Stop and ask for clarification if required inputs, permissions, safety boundaries, or success criteria are missing.

Automation and document limits

Verify the actual LibreOffice version, filters, Python UNO binding and database drivers; installing unrelated Python libraries does not provide UNO. Bind any UNO listener to loopback in a separate task-owned profile and stop it after use; UNO is not an authenticated sandbox. Do not terminate all office processes or expose the listener publicly. Use a fresh private output directory, check expected file type/nonempty output and inspect the rendered result; exit zero alone is insufficient.

Opening documents can invoke macros, external links or embedded content: use approved inputs with macros/updates disabled and isolate untrusted conversions. Format conversion may lose layout, formulas, links, notes, multiple sheets/pages or features. Retain originals, clarify CSV sheet/delimiter/encoding and preserve formula/identifier semantics. Do not automatically install packages, publish documents or put sensitive records in Git. These examples were statically reviewed only; no LibreOffice process or conversion was run.
