JPEGMetadata (extract EXIF)

function JPEGMetadata(imgFile: string): object;

Extracts meta-information (including full EXIF data) from a JPEG image file.

Parameters

Name	Type	Description
imgFile	string	Path to the JPEG image file to be analyzed.

Returns

A JSON object containing EXIF and other metadata fields. If extraction fails or the file is not a valid JPEG, an empty object is returned.

NOTE

The returned object may include fields such as Exif, Height, Width, and Valid. The exact fields depend on the image and its metadata. Some JPEGs may not contain EXIF data.

Example

var mdata = JPEGMetadata('./self_portrait.jpg');
Log(JSON.stringify(mdata, null, 2));

Example output:

{
  "Exif": {
    "ApertureValue": ["149/32"],
    "ColorSpace": [1],
    "DateTime": "2003:12:14 12:01:44",
    "Make": "Canon",
    "Model": "Canon PowerShot S40",
    // ... more EXIF fields ...
  },
  "Height": 360,
  "Valid": true,
  "Width": 480
}

TIP

For best results, ensure the input file is a valid JPEG with embedded EXIF metadata. Some image editors or converters may strip EXIF data from JPEGs.
