image-prep

Current version: 0.1.0

Image preparation and EXIF export tool

Modes

Currently there is only a one-shot mode called single that processes all images passed as arguments to the tool in one batch.

Usage

By default, all images passed as CLI arguments are resized to 500 and 1000 pixels on the longest size, using Lanczos3 as a resize algorithm. For each image, the EXIF information is dumped and stored in the output JSON index file. Optionally, the original image can be copied as-is to the output folder.

The index file contains all resized image filenames, and looks like this:

[
  {
    "original": {
      "dimension": {
        "width": 6016,
        "height": 4016
      },
      "exif": {
        "DateTime": "2023:08:13 13:48:28",
        "LensModel": "E 18-135mm F3.5-5.6 OSS",
        "Model": "ILCE-6400",
        "Make": "SONY",
        // etc
      }
    },
    "resized": [
      {
        "filename": "DSC00461-500px.jpg",
        "size": 500,
        "dimension": {
          "width": 500,
          "height": 334
        }
      },
      // repeated for each image size requested
    ]
  }
]

This index file is meant to be used by other tools, for instance to generate an image gallery in a static website.
