The example below shows how to add a "Scale & rotate" layer to an existing image: we will use this tool to create a preset that scales the image to a size of 800圆00 pixels at most (the "Scale & rotate" tool is found under the "geom" tab of the "new layer" dialog).
In order to create the presets, you first need to open an existing image with photoflow, and then add any layer that you want to save as a preset. All we need to do is to create a couple of presets for that, and then append them to the input file when calling pfbatch. The downscaling and sRGB conversions are additional operations that are not contained in the input PFI files, and that have to be applied to each image we are converting. You probably also want the web images to be converted to sRGB, just to make sure that they will display at least decently even on browsers that ignore ICC profiles. To make a concrete example, let's assume you have a certain number of edited images (saved as PFI files), and you want to create down-scaled versions to be posted on the web. load a PFI file, append some presets and save again as PFI.load a TIFF or JPeg file, apply some presets and export again as TIFF or JPeg.load a TIFF or JPeg file and save it as PFI file.export an existing PFI file to TIFF or JPeg, optionally applying additional presets (I'll come back to that later in this post).output_fileĪnd can be used to perform different kind of tasks: The general syntax of the pfbatch command is the following: The batch processor is called pfbatch and gets installed in the same directory as the interactive photoflow command.

You can download the sample files used in the tutorials from here.The development branch of PhotoFlow now provides a new command that allows some basic batch processing. Here is a screenshot showing the Curves tool applied to an image to increase the contrast: Tutorials Moreover, the layers structure can be saved to disk and re-opened again via the command line. The individual layers can be activated and de-activated using the radio buttons on the right of the image. The present version allows to open an image file and apply basic editing filters via non-destructive adjustment layers. PhotoFlow is in a early development stage.
The aim of the project is to provide a fully non-destructive photo retouching program that includes a complete workflow from RAW image development to high-quality printing.
