example of exif data from exifr module
const exifData = {"ImageWidth":2592,"ImageHeight":1944,"Make":"Google","Model":"Pixel 3","Orientation":"Rotate 90 CW","ModifyDate":"2022-03-06T16:47:30.000Z","ExposureTime":0.025011305,"FNumber":1.8,"ISO":284,"OffsetTime":"+07:00","ShutterSpeedValue":-5.32,"ApertureValue":1.69,"SubjectDistance":0.137,"Flash":"Flash did not fire","FocalLength":4.44,"SubSecTime":"592","ExifImageWidth":2592,"ExifImageHeight":1944,"SubjectDistanceRange":"Macro","GPSLatitudeRef":"N","GPSLatitude":[1,18,55.37],"GPSLongitudeRef":"E","GPSLongitude":[103,51,15.8],"GPSAltitudeRef":{"0":0},"GPSAltitude":65,"GPSTimeStamp":"16:47:2","GPSDateStamp":"2022:03:06","latitude":1.3153805555555556,"longitude":103.85438888888888}And then call this module
const exifValidation = require("exif-validation")pass the data from exif
const validate = exifValidation(exifData)
console.log(validate) // true or false
if value return from function is false then is not good exif, we should reject them
We expect true return from the module, and then allowing user to precess the image.
