- Other formats to ODP: PPTX, PPT, PDF
- Batch conversion of multiple files
3. Slide Automation
- Template-based slide generation
- Batch slide creation from data
- Automated content insertion
- Dynamic chart generation
4. Content Manipulation
- Text and image insertion
- Shape and diagram creation
- Animation and transition control
- Speaker notes management
5. Integration

Workflows
Creating a New Presentation
Method 1: Command-Line
soffice --impress template.odp
Method 2: Python with UNO
import uno
def create_presentation():
local_ctx = uno.getComponentContext()
resolver = local_ctx.ServiceManager.createInstanceWithContext(
"com.sun.star.bridge.UnoUrlResolver", local_ctx
)
ctx = resolver.resolve(
"uno:socket,host=localhost,port=8100;urp;StarOffice.ComponentContext"
)
smgr = ctx.ServiceManager
doc = smgr.createInstanceWithContext("com.sun.star.presentation.PresentationDocument", ctx)
slides = doc.getDrawPages()
slide = slides.getByIndex(0)
doc.storeToURL("file:///path/to/presentation.odp", ())
doc.close(True)
Converting Presentations
# ODP to PPTX
soffice --headless --convert-to pptx presentation.odp
# ODP to PDF
soffice --headless --convert-to pdf presentation.odp
# PPTX to ODP
soffice --headless --convert-to odp presentation.pptx
# Batch convert
for file in *.odp; do
soffice --headless --convert-to pdf "$file"
done
Template-Based Generation
import subprocess
import tempfile
from pathlib import Path
def generate_from_template(template_path, content, output_path):
with tempfile.TemporaryDirectory() as tmpdir:
subprocess.run(['unzip', '-q', template_path, '-d', tmpdir])
content_file = Path(tmpdir) / 'content.xml'
content_xml = content_file.read_text()
for key, value in content.items():
content_xml = content_xml.replace(f'${{{key}}}', str(value))
content_file.write_text(content_xml)
subprocess.run(['zip', '-rq', output_path, '.'], cwd=tmpdir)
return output_path
Format Conversion Reference
Supported Input Formats
- ODP (native), PPTX, PPT, PDF
Supported Output Formats
- ODP, PPTX, PDF, HTML, SWF
Command-Line Reference
soffice --headless
soffice --headless --convert-to <format> <file>
soffice --impress # Impress
Python Libraries
pip install ezodf # ODF handling
pip install odfpy # ODF manipulation
Best Practices
- Use slide masters for consistency
- Create templates for recurring presentations
- Embed fonts for PDF distribution
- Use vector graphics when possible
- Store ODP source files in version control
- Test conversions thoroughly
- Keep file sizes manageable
Troubleshooting
Cannot open socket
killall soffice.bin
soffice --headless --accept="socket,host=localhost,port=8100;urp;"
