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}");
}
}
}
}
}
