LastErrorCode after each function call let you see if the last call works or fails...

Thanks Ingo,

You are right, I didn't show it here, but the font was selected before. I'll go deep into the documentation anyway.

Hi Patrick,

in the description for both functions (ascent/descent) you can read "...Returns the size of the selected font...". But i don't see that you've already selected a font.
Try SelectFont first before you try to do the settings for a font ;-)
https://www.debenu.com/docs/pdf_library_reference/SelectFont.php
Here you'll find a lot for the first start:

Cheers and welcome here,
Ingo

Hi All,

I'm just trying to design a box under a text, for the value of the width it is correct, but I don't understand what's wrong with the height ?

Patrick

ie :

 with aPdf do
 begin      
       sTxt:='PROFORMA';
       SetTextSize(30);
       iWidth  := GetTextWidth(sTxt);
       iHeight:= GetTextAscent - GetTextDescent;

        iY:=10;
        iX:=130;
        SetFillColor(0.88,0.88,0.88);
        DrawBox(iX,iY,iWidth,iHeight,1);
        SetTextColor(1,0.13,0.13);
        DrawText(iX,(iY+iHeight),sTxt);
 end;
