<h3><a name="s03_07_16">3.7.16 </a>strings.inc</h3>
<p>
This include contains macros for manipulating and generating text strings.<a name="s03_07_16_i1"><a name="CRGBStr"></a>
</p>
<p>
<code>CRGBStr(C, MinLen, Padding)</code> and <code>CRGBFTStr(C, MinLen, Padding)</code><br> These macros convert a
color to a string. The format of the output string is "rgb < R, G, B>" or "rgbft < R, G, B, F,
T>", depending on the macro being called.<br> Parameters:
</p>
<ul>
<li>
<code>C</code> = The color to be turned into a string.
</li>
<li>
<code>MinLen</code> = The minimum length of the individual components, analogous to the second parameter of
str().
</li>
<li>
<code>Padding</code> = The padding to use for the components, see the third parameter of the str() function for
details.
</li>
</ul>
<a name="s03_07_16_i2"><a name="Str, strings.inc"></a>
<p>
<code>Str(A)</code>. This macro creates a string containing a float with the systems default precision. It is a
shortcut for using the str() function.<br> Parameters:
</p>
<ul>
<li>
<code>A</code> = The float to be converted to a string.
</li>
</ul>
<a name="s03_07_16_i3"><a name="Vstr, strings.inc"></a><a name="s03_07_16_i4"><a name="VStr2D, short form"></a>
<p>
<code>VStr2D(V), VStr(V)</code>. These macros create strings containing vectors using POV syntax (<X,Y,Z>)
with the default system precision. VStr2D() works with 2D vectors, VStr() with 3D vectors. They are shortcuts for
using the <code>vstr()</code> function.<br> Parameters:
</p>
<ul>
<li>
<code>V</code> = The vector to be converted to a string.
</li>
</ul>
<a name="s03_07_16_i5"><a name="Vstr2D, long form"></a>
<p>
<code>Vstr2D(V,L,P), Vstr(V,L,P)</code>. These macros create strings containing vectors using POV syntax
(<X,Y,Z>) with user specified precision. Vstr2D() works with 2D vectors, Vstr() with 3D vectors. They are
shortcuts for using the vstr() function. The function of L and P is the same as in <code>vstr</code> specified in <a href="s_97.html#s03_02_01_07_03">String
Functions</a>.<br> Parameters:
</p>
<ul>
<li>
<code>V</code> = The vector to be converted to a string.
</li>
<li>
<code>L</code> = Minimum length of the string and the type of left padding used if the string's representation is
shorter than the minimum.
</li>
<li>
<code>P</code> = Number of digits after the decimal point."
</li>
</ul>
<a name="s03_07_16_i6"><a name="Triangle_Str"></a>
<p>
<code>Triangle_Str(A, B, C)</code> and <code>Smooth_Triangle_Str(A, NA, B, NB, C, NC)</code><br> These macros take
vertex and normal information and return a string representing a triangle in POV-Ray syntax. They are mainly useful
for generating mesh files.<br> Parameters:
</p>
<ul>
<li>
<code>A, B, C</code> = Triangle vertex points.
</li>
<li>
<code>NA, NB, NC</code> = Triangle vertex normals (Smooth_Triangle_Str() only).
</li>
</ul>
<a name="s03_07_16_i7"><a name="Parse_String"></a>
<p>
<code>Parse_String(String)</code>. This macro takes a string, writes it to a file, and then includes that file.
This has the effect of parsing that string: "<code>Parse_String("MyColor")</code>" will be seen by
POV-Ray as "<code>MyColor</code>".<br> Parameters:
</p>
<ul>
<li>
<code>String</code> = The string to be parsed.
</li>
</ul>
