I was trying to read a file with OcrEditDemo which uses OcrWord and I see that the coordinates of captured words are different from coordinates captured using LEADDocument DocumentPageText

Here is my code that I tried to use

LoadDocumentOptions options = new LoadDocumentOptions();
options.UseCache = false;
using (LEADDocument document = DocumentFactory.LoadFromFile("C:\\Users\\Public\\Documents\\LEADTOOLS Images\\ocr1.tif", options))
_documentZoneWords = new List<List<DocumentWord>>();
document.Text.OcrEngine = _ocrEngine;
document.Text.TextExtractionMode = DocumentTextExtractionMode.Auto; //try to read as svg before ocr

DocumentPageText pageText = document.Pages[0].GetText();
if (pageText != null)

foreach (DocumentWord wd in pageText.Words)

List<DocumentWord> words = new List<DocumentWord>();



Bounds values captured in _documentZoneWords array are different from Bounds values captured using OcrEditDemo sample that are on _ocrZoneWords array

example of first word: "LEAD"
DocumentWord Bounds = {727.2;746.4;540;208,8}
OcrWord Bounds = {307;313;216;62}

Why are the values different?
Is there any way to convert Bounds of DocumentWord to Bounds of OcrWord to get same values?

Thanks in advance

can be solved using this:

LeadRect lr = document.Pages[0].RectToPixels(wd.Bounds);
