size of the font expressed in a 64-bit CY variable. The upper 32-bits of this value contains the integer point size and the lower 32-bits contains the fractional point size.<br />

I need exactly the opposite.<br />
<br />
I have the Height of the font, but I need to convert that Height in to PointSize (Not the rounded PointSize the exact PointSize). See my original post.

 Well, not sure if I understood you, but if &nbsp;' height = f (point_size) ' and the function f &nbsp;is bijective then you can calculate point_size=inverse_f( height). <br />
&nbsp; &nbsp; <br />
&nbsp;double &nbsp;dPointSize = (double)(-lfHEight * 72)/GetDeviceCaps(hDC, LOGPIXELSY);<br />
<br />
&nbsp;Am I missing something?

How to konw the exact size of a font from the point size to implement in an IFont-&gt;put_size?<br />
<br />
For example:<br />
<br />
Point size 8 is actually 8.25<br />
Point size 9 is actually 9<br />
Point size 10 is actually 9.75<br />
Point size 11 is actually 11.25<br />
Point size 12 is actually 12<br />
Point size 14 is actually 14.25<br />
<br />
Thanks

A font is a particular size, weight and style of a typeface. Each font is a matched set of type, one piece (called a "sort") for each glyph, and a typeface consists of a range of fonts that share an overall design. With the advent of digital typography, font is frequently synonymous with typeface, although the two terms do not necessarily mean the same thing. In particular, the use of "vector" or "outline" fonts means that different sizes of a typeface can be dynamically generated from one design. Each style may still be in a separate "font file" -- for instance, the typeface "Futura" may include the fonts "Futura roman", "Futura italic", "Futura bold" and "Futura extended" —- but the term "font" might be applied either to one of these alone or to the whole typeface.

Kernel and system programming is the process of creating the software necessary for a computer or device to function and operate other programs. Some operating systems (such as Microsoft Windows) are proprietary, but others, such as the various Linux distributions, are open source.
