Metadata Export for GIMP

This GIMP plug-in exports various metadata from the specified image into an XML, JSON or YAML file.

Metadata include image properties (e.g. name, dimensions) and a list of layers, channels, vectors and their properties (e.g. dimensions, position, visibility, color tags).

Installation

GIMP 2.10 is required.

1. In GIMP, locate the folder containing GIMP plug-ins - open GIMP and go to Edit → Preferences → Folders → Plug-Ins.
2. Copy the metadata_export folder inside one of the folders identified in step 1.

For Windows, make sure you have GIMP installed with support for Python scripting.

For Linux, make sure you use a GIMP installation bundled as Flatpak (which can be downloaded from the official GIMP page) or AppImage.

For macOS, make sure you have Python 2.7 installed.

Usage

Simply export an image like you normally would (File → Export...) and replace the file extension at the top of the export dialog with xml, json, or yaml. Alternatively, you may select one of these file extensions at the bottom of the export dialog.

To save the metadata programmatically (from the command line), use file-metadata-xml-save, file-metadata-json-save or file-metadata-yaml-save from the GIMP procedural database (PDB).

Example

Below is an example of image metadata in the JSON format. Only a select few entries are shown for brevity.

        "name": "loading_screen_template.xcf",
        "width": 1024,
        "height": 512,
