Please give a brief summary of your issue:
Get wrong text position by getTextPosition
Please describe your issue and provide steps to reproduce it:
Hi! I would like search a text then add an annotation at the position of text
I follow this article Get text position in PDF documents
and I use the webviewer-react-sample that you provide and try to implement the feature
here is my sample code
const doc = documentViewer.getDocument();
const searchTerm = 'Vendor Lock-in';
const pageNumber = documentViewer.getPageCount()
const pageText = await doc.loadPageText(pageNumber);
console.log('pageNumber', pageNumber);
console.log('pageText', pageText);
let startIndex = 0;
let endIndex = 0;
let quads;
while (startIndex > -1) {
startIndex = pageText.indexOf(searchTerm, endIndex);
endIndex = startIndex + searchTerm.length;
quads = await doc.getTextPosition(pageNumber, startIndex, endIndex);
}
const annotation = new Annotations.TextHighlightAnnotation();
annotation.PageNumber = pageNumber;
annotation.Quads = quads;
annotation.StrokeColor = new Annotations.Color(136, 39, 31);
annotationManager.addAnnotation(annotation);
annotationManager.redrawAnnotation(annotation);
as you can see the TextHighlightAnnotation should show up the same position as the text “Vendor Lock-in” that I search for, however the annotation show up on the left-top of page always, even I search another text on another page, annotation always show up on the left-top of page
do you have any suggestions for the case thanks
