Detailed description of issue
We are highlighting Text with TextHighlight tool on documents that where scanned and got a full ocr on them. The TextHighlight tool does not highlight the correct text height. Seems to just highlight half of the needed height.
Thats a problem for us, because we are exporting xfdf after annotation has been done and need correct coordinates in the xfdf. Even the coordinates in xfdf just show us half of the needed text height.
Adobe Reader does highlight the correct text height, though.

Expected behaviour
Highlight full text height like Adobe Reader TextHighlight tool does.

Does your issue happen with every document, or just one?
It happens on all scanned documents with ocr in it.

Code snippet
Not in code. Just viewer issue.

Maybe this should be filed as bug also?
Is there a way to set the TextHighlight heigt programatically?

Hi tomasz.trillo,

Sincere apologies for the delay, your post was initially removed so there have been no detection in the system.

You can get the quads of the highlight annotation created with the annotation properties:

And then use those quads for the textSelected function for the tool:

Also I was unable to download the file with the link, can you provide another link to the file?
