Applicable to JPEG, PNG, TIFF, and WebP images, the Exif method on an image Resource object returns an object containing Exif metadata.
To extract Exif, IPTC, and XMP metadata, use the Meta method instead.
Note
Metadata is not preserved during image transformation. Use this method with the original image resource to extract metadata from JPEG, PNG, TIFF, and WebP images.
Methods
Date
(time.Time) Returns the image creation date/time. Format with the time.Format function.
Lat
(float64) Returns the GPS latitude in degrees from Exif metadata.
Long
(float64) Returns the GPS longitude in degrees from Exif metadata.
Tags
(meta.Tags) Returns a collection of available Exif fields for this image. Availability is determined by the includeFields and excludeFields settings in your site configuration.
Examples
To list the creation date, latitude, and longitude:
{{ with resources.Get "images/a.jpg" }}
{{ with .Exif }}
<pre>
{{ printf "%-25s %v\n" "Date" .Date }}
{{ printf "%-25s %v\n" "Latitude" .Lat }}
{{ printf "%-25s %v\n" "Longitude" .Long }}
</pre>
{{ end }}
{{ end }}
To list the available Exif fields:
{{ with resources.Get "images/a.jpg" }}
{{ with .Exif }}
<pre>
{{ range $k, $v := .Tags -}}
{{ printf "%-25s %v\n" $k $v }}
{{ end }}
