|
|
<p> The QEmbed 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> QEmbed 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 Qt.
|
||
|
|
</ul>
|
||
|
|
<p> <h2> Output
|
||
|
|
</h2>
|
||
|
|
<a name="2"></a><p> The output from QEmbed 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">QImage</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">QByteArray</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 QEmbed and write a function
|
||
|
|
tailored to your needs.
