Examples

The following example demonstrates how to write metadata to a Tagged Image File Format (TIFF) image by using the IFD and Exif schemas.

BitmapMetadata tiffMetadata = new BitmapMetadata("tiff");
tiffMetadata.SetQuery("/ifd/{ushort=1000}", 9999);
tiffMetadata.SetQuery("/ifd/{uint=1001}", 23456);
tiffMetadata.SetQuery("/ifd/{uint=1002}", 34567);
tiffMetadata.SetQuery("/ifd/PaddingSchema:padding", (UInt32)4096);
tiffMetadata.SetQuery("/ifd/exif", new BitmapMetadata("exif"));
tiffMetadata.SetQuery("/ifd/exif/PaddingSchema:padding", (UInt32)4096);

Dim tiffMetadata As New BitmapMetadata("tiff")
tiffMetadata.SetQuery("/ifd/{ushort=1000}", 9999)
tiffMetadata.SetQuery("/ifd/{uint=1001}", 23456)
tiffMetadata.SetQuery("/ifd/{uint=1002}", 34567)
tiffMetadata.SetQuery("/ifd/PaddingSchema:padding", CType(4096, UInt32))
tiffMetadata.SetQuery("/ifd/exif", New BitmapMetadata("exif"))
tiffMetadata.SetQuery("/ifd/exif/PaddingSchema:padding", CType(4096, UInt32))
