Not necessarily.
, I'll try to prepare something. I need to analyze the harupdf source in C to see how the line spacing is handled when creating a text area. I'm not proficient in C 
, so give me some time to investigate.It will not be correct in every case, eg if you set a line spacing (leading) different from the default. The question remains of the font used and the line of the upper extension and the height between the baseline and the bottom line of the letter.

[BOLD [IF lBold]]
[ITALIC [IF lItalic]]

[STRIKEOUT [IF lStrikeout]]
[COLOR <aColor>]
[RIGHT | CENTER | JUSTIFY]
[WRAP]
[FONTSIZEFIT | HEIGHTFIT]
[GETBOTTOM <@nBottRowVar> ]
WRAP option: word-wrap even when there is no split character.
FONTSIZEFIT option: adjusting the font size (by reducing) so that all content fits within the declared area.
HEIGHTFIT option: adjusting the height of the area depending on: content, font, font size and set line spacing.
The FONTSIZEFIT and HEIGHTFIT options can not be used simultaneously.
Option GETBOTTOM <@nBottRowVar>: the variable <nBottRowVar> will get the value of the position of the bottom row of the printed area by reference. Value expressed in mm.
New feature:
_HMG_HPDF_GetHeight_MULTILINE_PRINT (<cText>, [<nLenght>], [<cFontName>], [<nFontSize>], [<lBold>], [<lItalic>], [<lWrap>]) --> nAreaHeight
Returns the calculated height of the printed area. Value expressed in mm. The height of the area depends on the function parameters and on the set line spacing ( SET HPDFPAGE LINESPACING TO <nSpacing> )
Arguments:
<cText> - printed content
<nLenght> - length of the line in mm (width of the area)
<cFontName> - font name
<nFontSize> - font size
<lBold> - .T. if the text is in bold
<lItalic> - .T. if the text is italic
<lWrap> - .T. if the word-wrap, even if there is no split character.
