Batch Processing

If you need to perform certain actions on a large number of files at once, use batch processing. Add borders, edit colors, apply various effects and filters, rename and resize images, recompress them, or perform a RAW conversion.

To find out whether your camera's RAW format is supported by the digiKam converter plug-in, check Help+Supported RAW Cameras. Use Batch+Convert Images to convert images from one format to another, for example from jpg to png.

An example of batch processing of images could involve applying a solarizing effect to a number of images. To queue images for batch processing and perform the actual processing, proceed as follows:

  1. Select Batch+Image Effects or right-click the album's name and select Batch Processes+Image Effects.

  2. Set the effect to Solarize and click Options to determine the degree of the effect to be applied and display an optional preview.

  3. Decide whether to rename or overwrite the original images, or even have them removed after the transformation has taken place.

  4. Set the target folder to hold the resulting images. If you do not want the new images to be written to the original folder, select New and add a new folder or subfolder. Select the new folder with your mouse pointer.

  5. Accept or modify the list of images queued for the transformation.

  6. Click Start to initiate the transformation.

    digiKam informs you about the progress and the success of the transformation.
