Get changes coordinates

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.

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

Coordinates calculation example

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);
}
