>             Project: PDFBox
>          Issue Type: Bug
>    Affects Versions: 1.8.8
>            Reporter: pupkin

> I use PDFBox 1.8.8 and try to add new text to existing pdf file. The problem is that text added by me is looking compressed for this specific pdf
>  
> [original pdf (i think this file is source of problem)|https://www.dropbox.com/s/foeb9raub20lbnx/1.pdf?dl=0]
> (it is working for other pdfs).
> [pdfbox generated file|https://www.dropbox.com/s/4e5ozksm5ycv7v2/2.pdf?dl=0]

>  
> It was not shown in all originally but i fixed problem with this command (set font display mode)
> {code}
> content.appendRawCommands("0 Tr ");  
> {code}
> I was working with pdf matrix and checked almost everything ... and do not see way how may i fix the problem...
> {code}
> content.setTextMatrix(1, 0, 0, 1, 0, 0);
> {code}
> questions:
> 1) why pdfbox not  ignore  page  font settings and use  default  options of font on page?
> 2) what mode was used in my pdf to archive such kind transformation how  i  may  fix   problem  to  show  font   correctly?
