Get text coordinates

GroupDocs.Viewer provides the feature of getting text coordinates. This feature is useful if you want to add selectable text over the image or implement a text search in image-based rendering.

The ExtractText property of ViewInfoOptions class enables you to get the text contained in a source document with coordinates.

Following code sample shows how to retrieve and print out text (lines / words / characters) of each document page with coordinates.

using (Viewer viewer = new Viewer("sample.docx"))
{
    bool extractText = true;
    ViewInfoOptions viewInfoOptions = ViewInfoOptions.ForPngView(extractText);
    ViewInfo viewInfo = viewer.GetViewInfo(viewInfoOptions);

    foreach(Page page in viewInfo.Pages)
    {
        Console.WriteLine($"Page: {page.Number}");
        Console.WriteLine("Text lines/words/characters:");
                            
        foreach (Line line in page.Lines)
        {
            Console.WriteLine(line);
            foreach (Word word in line.Words)
            {
                Console.WriteLine($"\t{word}");
                foreach (Character character in word.Characters)
                {
                    Console.WriteLine($"\t\t{character}");
                }
            }
        }
    }
}
