> Hey,
> I want to suggest a feature.
> I guess many people prefer to directly work with "mm" or "inches" instead of points. The common approach is to create an converter or ratio-Constant and convert at any place the "mm" or "inches" to points.
> I suggest an other approacher, what do you think about an central setting of an "unitconverter" so that every coordinate is converted deep inside shortly before rendering?
> I created a patch based on the 3.0.0-SNAPSHOT in [https://github.com/apache/pdfbox.git]
> I don't know the API enough to change all related Codelines. But this patch should give an Idea what i mean.
> For this approach I ignored:
>  * that actually die "PDPage" mediabox shoud be converted too.
>  * the Matrix arguments
>  
> {code:java}
> // Usage example
> UnitConverter.activeConverter=UnitConverter.MM_CONVERTER;
> try (PDDocument doc = new PDDocument())
> {
>     PDPage page = new PDPage(PDRectangle.A4); // works still unconverted 
>     doc.addPage(page);
>     
>     PDFont font = PDType1Font.HELVETICA_BOLD;
>     try (PDPageContentStream contents = new PDPageContentStream(doc, page))
>     {
>         contents.beginText();
>         contents.setFont(font, 12); //we are used to fontsizes, i would not use a converter here
>         contents.newLineAtOffset(10, 10);// x=10mm,y=10mm
>         contents.showText(message);
>         contents.endText();
>     }
>     
>     doc.save(filename);
> }
> {code}
