=====Selecting a font by pixel height=====

//by Richard Russell, July 2007//\\ \\  The BBC BASIC for Windows [[http://www.bbcbasic.co.uk/bbcwin/manual/bbcwin8.html#font|*FONT]] command selects the font size in **points** (nominally units of 1/72 inch), and as a consequence the character height in **pixels** varies acccording to the current Dots Per Inch setting. This is the way font size selection in Windows normally works and is what you would expect. See the article [[/Supporting%20different%20DPI%20values|Supporting different DPI values]] for more information.\\ \\  However there can be occasions when you would prefer the font height to be a specific size in pixels and not to change according to the DPI setting. For example you may wish the text to align with a graphic image which isn't scaled according to the DPI. To do that use the following code:\\ 
<code bb4w>
        @vdu%!220 = PixelHeight%
        *FONT FaceName
</code>
Note particularly that **no size** is specified in the *FONT command. So for example if you wanted to select the Arial font with a height of 40 pixels you could do that as follows:\\ 
<code bb4w>
        @vdu%!220 = 40
        *FONT Arial
</code>
This sets the height of the character **cell**. You can alternatively set the height of the character itself (i.e. excluding the //internal leading//) by specifying a negative value:\\ 
<code bb4w>
        @vdu%!220 = -40
        *FONT Arial
</code>

**BBC BASIC for Windows version 6 only**:\\ \\  You can optionally specify a style such as **bold**, //italic// or __underlined__ as follows:\\ 
<code bb4w>
        @vdu%!220 = 40
        *FONT Arial,B
</code>
You can also set the character's width independently of its height:\\ 
<code bb4w>
        @vdu%!216 = -40
        @vdu%!220 = 40
        *FONT Arial
</code>
Note that you must specify the width as a negative value.
