JpegWriter.Exif Property

Gets/sets EXIF data collection you want to write into the file.

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

Syntax

Visual Basic

Public Property Exif As ExifDictionary

C#

public ExifDictionary Exif { get; set; }

Property Value

ExifDictionary class instance that contains EXIF data collection you want to write into the file.

Implements

IMetadataWriteSupport.Exif

Examples

JPEG files can store EXIF and IPTC data blocks. Graphics Mill for .NET allows you extracting this data from the JPEG file and save it into another JPEG file (as well as into the other file format which supports EXIF and IPTC). This code sample demonstrates how to add the EXIF and IPTC data to the file:

Visual Basic

Dim bitmap As New Aurigma.GraphicsMill.Bitmap("c:\Mountain.jpg")

Dim writer As New Aurigma.GraphicsMill.Codecs.JpegWriter("C:\Mountain2.jpg")

'EXIF
Dim exif As New Aurigma.GraphicsMill.Codecs.ExifDictionary
exif(Aurigma.GraphicsMill.Codecs.ExifDictionary.Software) = "Aurigma Graphics Mill"

writer.Exif = exif

'IPTC
Dim iptc As New Aurigma.GraphicsMill.Codecs.IptcDictionary
iptc(Aurigma.GraphicsMill.Codecs.IptcDictionary.Category) = "Nature"
iptc(Aurigma.GraphicsMill.Codecs.IptcDictionary.CopyrightNotice) = "Aurigma Inc."
iptc(Aurigma.GraphicsMill.Codecs.IptcDictionary.Keyword) = "mountain"

writer.Iptc = iptc

'Adobe resource blocks
Dim adobeResources As New Aurigma.GraphicsMill.Codecs.AdobeResourceDictionary
'Create new adobe image resource block with the required metadata
Dim arBlock As New Aurigma.GraphicsMill.Codecs.AdobeResourceBlock("Copyright", New Byte() {1})
'Set this block to the item with 0x040A ID (copyright flag)
adobeResources.Item(&H40A) = arBlock

writer.AdobeResources = adobeResources

'XMP
Dim xmp As New Aurigma.GraphicsMill.Codecs.XmpData()
'Create a node with the required metadata
Dim node As New Aurigma.GraphicsMill.Codecs.XmpValueNode( _
    Aurigma.GraphicsMill.Codecs.XmpNodeType.SimpleProperty, _
    "John Doe", _
    Aurigma.GraphicsMill.Codecs.XmpTagNames.DCCreator)
xmp.AddNode(node)

writer.Xmp = xmp.Save()

Dim frame As New Aurigma.GraphicsMill.Codecs.JpegFrame(50, True)

frame.SetBitmap(bitmap)

bitmap.Dispose()

writer.AddFrame(frame)

frame.Dispose()

writer.Dispose()

C#
