This is an updated fork of ExifLibrary, a .Net Standard and .NET library for editing Exif metadata contained in image files.
It mainly removes the dependency on netstandard1.3
to avoid pulling in loads of dependencies and has merged a PR for better DateTime parsing.
If you are using NuGet you can install it with:
PM> Install-Package ExifLibNet.Updated
To read an image file and extract metadata:
var file = ImageFile.FromFile("path_to_image");
// the type of the ISO speed rating tag value is unsigned short
// see documentation for tag data types
var isoTag = file.Properties.Get<ExifUShort>(ExifTag.ISOSpeedRatings);
// the flash tag's value is an enum
var flashTag = file.Properties.Get<ExifEnumProperty<Flash>>(ExifTag.Flash);
// GPS latitude is a custom type with three rational values
// representing degrees/minutes/seconds of the latitude
var latTag = file.Properties.Get<GPSLatitudeLongitude>(ExifTag.GPSLatitude);
To add metadata:
var file = ImageFile.FromFile("path_to_image");
// note the explicit cast to ushort
file.Properties.Set(ExifTag.ISOSpeedRatings, <ushort>200);
//for pngs
var pngText = new PngText(ExifTag.PNGTagName, ...)
file.Properties.Set(pngText)
To save the image with metadata:
file.Save("path_to_image");
