	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. Patrick

	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: http://www.quickpdf.org/ Cheers and welcome here, Ingo
	Cheers, 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;
