[~tilman] On your screenshot only
[CropBox|https://wiki.scribus.net/canvas/PDF_Boxes_:_mediabox,_cropbox,_bleedbox,_trimbox,_artbox]
of the document is shown. Our application works fine in this mode too. Also,
we have the code dealing with scaling of type 3 fonts, I've cut it from snippet
because the issue is not related to specific fonts at all.
Seems it is related somehow to in page boxes of the document (CropBox,
MediaBox, etc..), and the issue is only on the first page of the document.
Also, note that on the first page different fonts (or at least sizes) used.
But, all glyphs are shifted top by the same amount, which equals to nearly 8 or
9.
I've attached full document: [^00051-2a7-00052-2a7.pdf]
P.S. We actually required to use glyph boxes which correspond to blue ones on
your screenshot (but not cyan). This is because our highlightings required to
be similar to text selection in Adobe Reader. In CropBox mode, our software
works exactly as blue boxes on your screenshot. But have you a code that can
render full MediaBox with correct blue boxes?
When a browser displays full Media Box, there is some extra space used to
display it. Our current code takes this into account by adding this space as
shown below. It works fine mostly on all docs, but the only issue with the
first page of attached sample.
{code}
if (!useCropBox) {
float dx = pdPage.findMediaBox().getLowerLeftX() -
pdPage.findCropBox().getLowerLeftX()
float dy = pdPage.findMediaBox().getLowerLeftY() -
pdPage.findCropBox().getLowerLeftY()
shift(dx, dy);//adds dx and dy values to ALL coordinates
}
{code}

> We have tried this on both 1.8.12 and 2.0.3 versions and got the same result
> - character positions are shifted up.
> We are assuming X and Y positions are relative to CropBox.
> See [^screenshot-1.png], yellow highlights are upper than the texts.
> PDF doc is attached.
