<p> The TQEmbed tool, found in <tt>qt/tools/qembed</tt>, converts arbitrary files
into C++ code. This is useful for including image files and other resources
directly into your application rather than loading the data from external
files.
<p> TQEmbed can also generate uncompressed versions of images that can be included
directly into your application, thus avoiding both the external file and the
need to parse the image file format. This is useful for small images such as
icons for which compression is not a great gain.
<p> <h2> Usage
</h2>
<a name="1"></a><p> <pre>
    qembed [ general-files ] [ --images image-files ]
</pre>
 
<p> <ul>
<li> <tt>general-files</tt>
<p> These files can be any type of file.
<p> <li> <tt>--images image-files</tt>
<p> These files must be in image formats supported by TQt.
</ul>
<p> <h2> Output
</h2>
<a name="2"></a><p> The output from TQEmbed is a C++ header file which you should
include in a C++ source file. In the source file, you should make a
wrapper function that suits your application. Two functions are
provided; your wrapper function could just call one of these, or
you can implement your own. Here's a simple example of usage for each
of the supplied functions:
<p> <h3> qembed_findImage()
</h3>
<a name="2-1"></a><p> <pre>
    #include "generated_qembed_file.h"

    <a href="qimage.html">TQImage</a> myFindImage(const char* name)
    {
        return qembed_findImage(name);
    }
</pre>
 
<p> Just call the generated function; <em>name</em> is the original image
filename <b>without</b> the extension.
<p> <h3> qembed_findData()
</h3>
<a name="2-2"></a><p> <pre>
    #include "generated_qembed_file.h"

    <a href="qbytearray.html">TQByteArray</a> myFindData(const char* name)
    {
        return qembed_findData(name);
    }
</pre>
 
<p> Just call the generated function; <em>name</em> is the original filename
<b>with</b> the extension
<p> Alternatively, look at the output from TQEmbed and write a function
tailored to your needs.
