|

| 35 |
|
|---|
| 36 | <p> The QEmbed tool, found in <tt>qt/tools/qembed</tt>, converts arbitrary files
|
|---|
| 37 | into C++ code. This is useful for including image files and other resources
|
|---|
| 38 | directly into your application rather than loading the data from external
|
|---|
| 39 | files.
|
|---|
| 40 | <p> QEmbed can also generate uncompressed versions of images that can be included
|
|---|
| 41 | directly into your application, thus avoiding both the external file and the
|
|---|
| 42 | need to parse the image file format. This is useful for small images such as
|
|---|
| 43 | icons for which compression is not a great gain.
|
|---|
| 44 | <p> <h2> Usage
|
|---|
| 45 | </h2>
|
|---|
| 46 | <a name="1"></a><p> <pre>
|
|---|
| 47 | qembed [ general-files ] [ --images image-files ]
|
|---|
| 48 | </pre>
|
|---|
| 49 |
|
|---|
| 50 | <p> <ul>
|
|---|
| 51 | <li> <tt>general-files</tt>
|
|---|
| 52 | <p> These files can be any type of file.
|
|---|
| 53 | <p> <li> <tt>--images image-files</tt>
|
|---|
| 54 | <p> These files must be in image formats supported by Qt.
|
|---|
| 55 | </ul>
|
|---|
| 56 | <p> <h2> Output
|
|---|
| 57 | </h2>
|
|---|
| 58 | <a name="2"></a><p> The output from QEmbed is a C++ header file which you should
|
|---|
| 59 | include in a C++ source file. In the source file, you should make a
|
|---|
| 60 | wrapper function that suits your application. Two functions are
|
|---|
| 61 | provided; your wrapper function could just call one of these, or
|
|---|
| 62 | you can implement your own. Here's a simple example of usage for each
|
|---|
| 63 | of the supplied functions:
|
|---|
| 64 | <p> <h3> qembed_findImage()
|
|---|
| 65 | </h3>
|
|---|
| 66 | <a name="2-1"></a><p> <pre>
|
|---|
| 67 | #include "generated_qembed_file.h"
|
|---|
| 68 |
|
|---|
| 69 | <a href="qimage.html">QImage</a> myFindImage(const char* name)
|
|---|
| 70 | {
|
|---|
| 71 | return qembed_findImage(name);
|
|---|
| 72 | }
|
|---|
| 73 | </pre>
|
|---|
| 74 |
|
|---|
| 75 | <p> Just call the generated function; <em>name</em> is the original image
|
|---|
| 76 | filename <b>without</b> the extension.
|
|---|
| 77 | <p> <h3> qembed_findData()
|
|---|
| 78 | </h3>
|
|---|
| 79 | <a name="2-2"></a><p> <pre>
|
|---|
| 80 | #include "generated_qembed_file.h"
|
|---|
| 81 |
|
|---|
| 82 | <a href="qbytearray.html">QByteArray</a> myFindData(const char* name)
|
|---|
| 83 | {
|
|---|
| 84 | return qembed_findData(name);
|
|---|
| 85 | }
|
|---|
| 86 | </pre>
|
|---|
| 87 |
|
|---|
| 88 | <p> Just call the generated function; <em>name</em> is the original filename
|
|---|
| 89 | <b>with</b> the extension
|
|---|
| 90 | <p> Alternatively, look at the output from QEmbed and write a function
|
|---|
| 91 | tailored to your needs.
