How to get coordinates of a searched words was created by abhishekjaju

I am trying hard to get coordinates of a searched word in a PDF page.
For example I have searched a word adobe in a pdf page, now I am not able to get the coordinates of this searched word.
I need to add a annotation to this search word and without getting the coordinates I am not able to add annotation to this searched word.

You can implement it yourself using:

www.androidpdf.mobi/documentation/javado...ml#GetFirstChar(int)
www.androidpdf.mobi/documentation/javado...html#ObjsGetCharRect (int, float[])

The first method will return the index of the first char, you need to pass that index to the second method, and the second method will fill the float[] with the rect of that char...
Then you need to do the same for the last char..and calculate the coordinates of the whole word.

Can you please explain with a example.
I am getting a error.
I am getting the Index of first character of the word , then I am adding the searched word length to find index of last character.
But the above method is giving a error.

this is an example of searching a word and adding annotation to it:

Code:

Page currentPage = m_doc.GetPage(page);
currentPage.ObjsStart();
String str = "radaee";
Finder mFinder = currentPage.FindOpen(str, false, false);
if( mFinder != null ) { 
	int ichar = mFinder.GetFirstChar(0);
	int ichar_end = ichar + str.length() - 1;
	float rect[] = new float[4];
	float rect_end[] = new float[4];
	currentPage.ObjsGetCharRect(ichar, rect);
	currentPage.ObjsGetCharRect(ichar_end, rect_end);
			
	//currentPage.AddAnnotMarkup(ichar, ichar_end, 0);
			
	currentPage.AddAnnotURI(new float[]{rect[0], rect[1], rect_end[2], rect_end[3]}, "http://www.androidpdf.mobi");
			
	//rerender the page to see the annotation
}
