[Qt-interest] pdf printer 1200 DPI and font size

[Tony Rietwyk]

Hi Sylvain, 
 
Now that the transform from mm to printer pixels is working OK, converting
font sizes from points (= 1/72 of an inch) to mm should be straight forward.
To correctly measure an individual character, you will need to get the
character's tightBoundingRect from the QFontInfo.  
 
Hope that helps, 
 
Tony

What should I put in setPointSizeF if I use the transform like below? 


    QTransform transformMM = QTransform::fromScale(
        printer.physicalDpiX() / 25.400,
        printer.physicalDpiY() / 25.400
    );
    painter.setWorldTransform(transformMM, false);

setPixelSize() seems to give correct but it is only integer...


do you have any idea?
