Example
using Leadtools;
using Leadtools.Codecs;
using Leadtools.ImageProcessing;
using Leadtools.ImageProcessing.Color;
using Leadtools.Svg;
public void MetadataAutoLoadExample()
{
// Prompt the user for an image file
string imageFileName = PromptForFileName();
// Initialize LEADTOOLS
using (RasterCodecs codecs = new RasterCodecs())
{
CodecsLoadOptions loadOptions = codecs.Options.Load;
// Make sure auto-loading of markers is turned off, otherwise,
// markers take precedence over loading the other metadata
loadOptions.Markers = false;
// Automatically load any tags, comments and geokeys found in this file
loadOptions.Tags = true;
loadOptions.Comments = true;
loadOptions.GeoKeys = true;
// Now load the image
using (RasterImage image = codecs.Load(imageFileName, 0, CodecsLoadByteOrder.BgrOrGray, 1, 1))
{
string txtFileName = Path.Combine(
Path.GetDirectoryName(imageFileName),

using (StreamWriter writer = File.CreateText(txtFileName))
{
// Show its tags
ShowTags(writer, "Tags", image.Tags);
// Show its comments
ShowComments(writer, image.Comments);
// Show its geo keys (tags and geokeys use the same data type)
ShowTags(writer, "GeoKeys", image.GeoKeys);
}
// Show the text file we created
System.Diagnostics.Process.Start(txtFileName);
}
}
