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;

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


Cheers,
Ingo

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.

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