Detailed Description

Exif is a standard for embedding metadata into image, audio and related file types, widely used by digital cameras and other equipment. Exif image metadata include image tags, extended tags and GPS tags that correspond to various image attributes. The tags are well-known codes. You can read about the Exif standard at http://www.jeita.or.jp.

The following code logs to the console some Exif information from a file containing an image.

ExifInfo {
    id: exif1
    filePath: "C:/temp/sample.jpg"

    function logExifMetadata() {
        console.log(
                    "\nFile:              " + exif1.filePath +
                    "\nCreated:           " + exif1.created +
                    "\nIs Exif valid?     " + exif1.isExifValid +
                    "\nExif version:      " + exif1.extendedValue(0x9000) +
                    "\nCamera manuf:      " + exif1.imageValue(0x010F) +
                    "\nCamera model:      " + exif1.imageValue(0x0110) +

                    "\nGPS speed:         " + exif1.gpsValue(0x000D) +
                    "\nAll image tags:    " + exif1.imageTags +
                    "\nAll extended tags: " + exif1.extendedTags +
                    "\nAll GPS tags:      " + exif1.gpsTags);
