This effect applies an emboss convolution to a single source. The performance of the embossing operation is determined by the convolution kernel. This is a matrix of values applied to each pixel of the source to produce the resulting image.

This effect takes a maximum of one source.

The QTPlgEffectEmbossDesc class implements methods and properties to setup programmatically the parameters of the emboss effect provided natively by QuickTime.







The QTPlgEffectEmbossDesc class constructors are called when you create a new instance of the class, while the ˜QTPlgEffectEmbossDesc class destructor, is called automatically when the class is no more in use. Also, you can invoke the class destructor by setting the instance of the class to nil.
Once a new class instance is returned, it is good practice to check the class property to be sure that the new object can be used. For discussion about the validity of an effect description instance see the documentation relative to the .

The class provides you with the following initializer methods:
()
This is the default constructor. Use this constructor to create a completely new data descriptor container in memory.
(other as )
This is the copy constructor. The properties of the object to be copied will be used to initialize the new class instance properties. Note that the parameter passed is a generic object; this is due to the fact that you could use a descriptor obtained by the that returns a generic . Anyway, the class makes a control to check if the passed object is suitable for use and, if not, will initialize the class instance with default values

specifies the size of the emboss kernel to apply. This value must be one of 3, 5, 7, 9, 11, 13 or 15. Larger kernels will produce a more heavily embossed result
