<p>Hello Dheeraj,</p>
I think fontconfig.h does not provide any function calculating
string or character width.<br>
But Xft.h does.<br>
You extract pertinent data from your FcPattern like family, size,
slant, weight and for you spacing which must be 0.<br>
Then you open your font like this (example) :
<p>XftFont * font=XftFontOpenName(display,screen,newFont);</p>
<p>where newFont could be "Liberation
Sans-12:bold:roman:proportional"</p>
<p>You can now calculate the width of the character 'm' via this
command :<br>
</p>
XGlyphInfo glyphInfo;<br>
XftTextExtentsUtf8 (display,font,"m",1,&glyphInfo);
<p>glyphInfo.width contains the width of your character<br>
</p>

<br>
Even if you change a value in FC_SPACING property, that won't
change<br>
the feel of "Width of each character is different" because
that is the<br>
reason why it was PROPORTIONAL. that is just a cache from a
font to<br>
query a best font against a request. that won't affect the
rendering<br>
directly.<br>
