Using the

size = MeasureString(txt,font)

function I notice a trailing space is ignored.

Both
txt = "1234567890"
and
txt = "1234567890 "

give me the same value of size.width
Do I overlook something or is this know behavior?

Best regards,
Maarten

This is the known behavior. Trailing spaces have no impact on the output in PDF. Spaces in the middle of the string are measured as they have impact on the result.

Here's a trick that determines the width of a blank:
https://github.com/empira/PDFsharp/blob ... ter.cs#L81

Code:
_spaceWidth = _gfx.MeasureString("x x", value).Width;
_spaceWidth -= _gfx.MeasureString("xx", value).Width;

Thanks for the quick responds.

I use the space width calculation routine as mentioned.
