NAME
       QImageFormatType - Factory that makes QImageFormat objects

SYNOPSIS
       #include <qasyncimageio.h>

   Public Members
       virtual ~QImageFormatType ()
       virtual QImageFormat * decoderFor ( const uchar * buffer, int length )
	   = 0
       virtual const char * formatName () const = 0

   Protected Members
       QImageFormatType ()

DESCRIPTION
       The QImageFormatType class is a factory that makes QImageFormat
       objects.

       Whereas the QImageIO class allows for complete loading of images,
       QImageFormatType allows for incremental loading of images.

       New image file formats are installed by creating objects of derived
       classes of QImageFormatType. They must implement decoderFor() and
       formatName().

       QImageFormatType is a very simple class. Its only task is to recognize
       image data in some format and make a new object, subclassed from
       QImageFormat, which can decode that format.

       The factories for formats built into Qt 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.

       See also Graphics Classes, Image Processing Classes, and Multimedia
       Classes.

MEMBER FUNCTION DOCUMENTATION
QImageFormatType::QImageFormatType () [protected]
       Constructs a factory. It automatically registers itself with
       QImageDecoder.

QImageFormatType::~QImageFormatType () [virtual]
       Destroys a factory. It automatically unregisters itself from
       QImageDecoder.

QImageFormat * QImageFormatType::decoderFor ( const uchar * buffer, int length
       ) [pure virtual]
       Returns a decoder for decoding an image that starts with the bytes in
       buffer. The length of the data is given in length. This function should
       only return a decoder if it is certain that the decoder applies to data
       with the given header. Returns 0 if there is insufficient data in the
       header to make a positive identification or if the data is not
       recognized.

const char * QImageFormatType::formatName () const [pure virtual]
       Returns the name of the format supported by decoders from this factory.
       The string is statically allocated.
