ImGearFormatMetadata Class

The TIFF Property, EXIF Property, IPTC Property and XMP Property of ImGearMetadataHead Class, defined in the ImageGear21.Core assembly, use ImGearFormatMetadata Class type. ImGearFormatMetadata Class does not have any public members. If the application uses Simplified Metadata API, it shall cast TIFF, EXIF, IPTC and XMP properties to actual classes ImGearTIFFMetadata Class, ImGearEXIFMetadata Class, ImGearIPTCMetadata Class and ImGearXMPMetadataRoot Class, respectively. These classes are defined in the ImageGear21.Formats.SimplifiedMetadata assembly. The following two examples demonstrate this:

C#	Copy Code
using ImageGear.Formats.XMP; ImGearPage page; // Load an image into ImGearPage // a String description = "<Empty>"; if (imGearPage.Metadata.XMP != null) { ImGearXMPMetadataRoot xmp = imGearPage.Metadata.XMP as ImGearXMPMetadataRoot; if ((xmp.DublinCore != null) && (xmp.DublinCore.Description != null) && (xmp.DublinCore.Description.Default != null)) description = xmp.DublinCore.Description.Default; }

Copy Code

using ImageGear.Formats.XMP;
ImGearPage page;
// Load an image into ImGearPage
// a
String description = "<Empty>";
if (imGearPage.Metadata.XMP != null)
{
 ImGearXMPMetadataRoot xmp = imGearPage.Metadata.XMP as ImGearXMPMetadataRoot;
 if ((xmp.DublinCore != null) && 
  (xmp.DublinCore.Description != null) && 
  (xmp.DublinCore.Description.Default != null))
   description = xmp.DublinCore.Description.Default;
}

VB.NET	Copy Code
Imports ImageGear.Formats.XMP Dim imGearPage As ImGearPage ' Load an image into ImGearPage ' ... imGearPage = igPage Dim description As String = "<Empty>" If imGearPage.Metadata.XMP IsNot Nothing Then Dim xmp As ImGearXMPMetadataRoot = imGearPage.Metadata.XMP If ((xmp.DublinCore IsNot Nothing) And (xmp.DublinCore.Description IsNot Nothing) And (xmp.DublinCore.Description.Default IsNot Nothing)) Then description = xmp.DublinCore.Description.Default End If End If

VB.NET

Copy Code

Imports ImageGear.Formats.XMP
Dim imGearPage As ImGearPage

imGearPage = igPage
Dim description As String = "<Empty>"
If imGearPage.Metadata.XMP IsNot Nothing Then
   Dim xmp As ImGearXMPMetadataRoot = imGearPage.Metadata.XMP
   If ((xmp.DublinCore IsNot Nothing) And (xmp.DublinCore.Description IsNot Nothing) And (xmp.DublinCore.Description.Default IsNot Nothing)) Then description = xmp.DublinCore.Description.Default

End If
