Python Interface for the Adobe DNG Converter

PyDNGConverter

Python Interface for the Adobe's DNG Converter.

Utilizing parallel processing, PyDNGConverter can convert RAW images to DNG up to ~60% faster than simply utilizing Adobe's DNG Converter.

Installation

pip install -U pydngconverter

To utilize PyDNGConverter's Exif thumbnail extraction (as opposed to Adobe DNG Converters'), the following dependencies are required:

• ExifTool
• ImageMagick

Then specify JPEGPreview.EXTRACT for DNGConverters jpeg_preview parameter.

Alternatively, you can utilize Adobe DNG Converters' thumbnail extraction via:

• JPEGPreview.MEDIUM
• JPEGPreview.FULL

Or, disable thumbnails via:

• JPEGPreview.NONE

Example

import asyncio
from pydngconverter import DNGConverter, flags

async def main():
    # Create converter instance.
    pydng = DNGConverter('/my/raw/files/',
                        dest='/dngfiles',
                        jpeg_preview=flags.JPEGPreview.EXTRACT,
                        fast_load=True,
                        )
    # Convert all
    return await pydng.convert()

loop = asyncio.get_event_loop()
loop.run_until_complete(main())
loop.close()
