<p>The TQImageFormatType class is a factory that makes TQImageFormat objects.
The TQImageFormatType class is a factory that makes <ahref="qimageformat.html">TQImageFormat</a> objects.
<p>
<p> Whereas the <ahref="qimageio.html">TQImageIO</a> class allows for <em>complete</em> loading of
images, TQImageFormatType allows for <em>incremental</em> loading of
images.
<p> New image file formats are installed by creating objects of
derived classes of TQImageFormatType. They must implement
<ahref="#decoderFor">decoderFor</a>() and <ahref="#formatName">formatName</a>().
<p> TQImageFormatType is a very simple class. Its only task is to
recognize image data in some format and make a new object,
subclassed from TQImageFormat, which can decode that format.
<p> The factories for formats built into TQt are automatically defined
before any other factory is initialized. If two factories would
recognize an image format, the factory created last will override
the earlier one; you can thus override current and future built-in
formats.
