Hi,

I'm wondering if there's a way to set the font size of an annotation in points (i.e. the Font.Size) property as well as the ObjFontHeight[idx] ?

When I retrieve the ObjfontHeight of an object is often returns -16, indicating that there's a size property available?

Thanks
Stuart

Hi Stuart

ObjFontHeight simply points to a Logfont lfHeight, so negative values should be supported. What issues do you encounter when doing so?

Hi Nigel,

I'm just trying to hook up a spin edit to show and set the font height of the selected object. When I select an object, I usually get -16 in the spin edit.

I'm not familiar with a "logfont lfHeight" -- is there some formula to convert to a recognisable "point size" ?

Cheers

Thanks Nigel - I realise I spoke before searching. I will look at that link thanks.

I also found this in case anyone else is wondering:
