JpegReader.Exif Property

Gets EXIF data collection from file.

Namespace: Aurigma.GraphicsMill.Codecs
Assembly: Aurigma.GraphicsMill (in Aurigma.GraphicsMill.dll)

Syntax

Visual Basic

Public ReadOnly Property Exif As ExifDictionary

C#

public ExifDictionary Exif { get; }

Property Value

ExifDictionary class instance that contains EXIF data collection obtained from the file.

Implements

IMetadataReadSupport.Exif

Examples

The code below demonstrates how to extract and display both EXIF and IPTC data.

Visual Basic

Dim bitmap As New Aurigma.GraphicsMill.Bitmap

'Read bitmap and metadata
Dim jpegReader As New Aurigma.GraphicsMill.Codecs.JpegReader("C:\IMG_0001.jpg")

'Read metadata
Dim exif As Aurigma.GraphicsMill.Codecs.ExifDictionary = jpegReader.Exif
Dim iptc As Aurigma.GraphicsMill.Codecs.IptcDictionary = jpegReader.Iptc

'Read bitmap
Dim frame As Aurigma.GraphicsMill.Codecs.Frame = jpegReader.LoadFrame(0)
frame.GetBitmap(bitmap)

frame.Dispose()

jpegReader.Dispose()

'Show EXIF tags
If Not exif Is Nothing Then
    Console.WriteLine("EXIF")
    Console.WriteLine("---------------")
    For Each key As Long In exif.Keys
        Console.WriteLine("{0}: {1}, {2}", exif.GetKeyDescription(key), _
         exif.Item(key), exif.GetItemString(key))
    Next
End If

'Show IPTC tags
If Not iptc Is Nothing Then
    Console.WriteLine("IPTC")
    Console.WriteLine("---------------")
    For Each key As Long In iptc.Keys
        Console.WriteLine("{0}: {1}, {2}", iptc.GetKeyDescription(key), _
         iptc.Item(key), iptc.GetItemString(key))
    Next
End If
