Get changes coordinates Leave feedback

GroupDocs.Comparison allows to detect changes between source and target documents and obtain changes coordinates at document preview images. These coordinates can be quite useful for highlighting detected changes at document preview images with some graphics (for example, place a red rectangle around each detected change).

The following are the steps to obtain changes coordinates.

• Instantiate Comparer object with source document path or stream;
• Call Add method and specify target document path or stream;
• Instantiate CompareOptions object and set CalculateCoordinates property to true;
• Call Comparer method and pass CompareOptions object from previous step;
• Call GetChanges method.

The following code sample shows how to compare multiple documents with specific options.

using (Comparer comparer = new Comparer("source.docx"))
{
	comparer.Add("target.docx");
    CompareOptions compareOptions = new CompareOptions(){ CalculateCoordinates = true };
    comparer.Compare(compareOptions);
    ChangeInfo[] changes = comparer.GetChanges();
    foreach (ChangeInfo change in changes)
    	Console.WriteLine("Change Type: {0}, X: {1}, Y: {2}, Text: {3}", change.Type, change.Box.X, change.Box.Y, change.Text);
}
