* ImageBitmapFormatUtils is an abstract class which provides interfaces to
|
|
* extract information of each ImageBitmapFormat and interfaces to convert
|
|
* image data between different ImageBitmapFormats. For each kind of
|
|
* ImageBitmapFromat, we derive a subclass from the ImageBitmapFormatUtils to
|
|
* implement functionalities that are subject to the specific ImageBitmapFormat.
|
|
*
|
|
* ImageBitmapFormatUtils is an abstract class and its sub-classes are designed
|
|
* as singletons. The singleton instance of sub-classes could be initialized and
|
|
* accessed via the ImageBitmapFormatUtils::GetUtils() static method. The
|
|
* singleton instance is a static local variable which does not need to be
|
|
* released manually and, with the C++11 static initialization, the
|
|
* initialization is thread-safe.
|
|
*
|
|
* ImageBitmapFormatUtils and its sub-classes are designed to unify operations
|
|
* of ImageBitmap-extensions over different kinds of ImageBitmapFormats; they
|
|
* provide following functionalities:
|
|
*
|
|
* (1) Create default/customized ImagePixelLayout object of each kind of
|
|
* ImageBitmapFormat.
|
|
* (2) Store the channel counts of each ImageBitmapFormat.
|
|
* (3) Calculate the needed buffer size of each kind of ImageBitmapFormat with
|
|
* given width, height and stride.
|
|
* (4) Perform color conversion between supported ImageBitmapFormats. We use
|
|
* _double dispatching_ to identify the source format and destination format
|
|
* at run time. The _double dispatching_ here is mainly implemented by
|
|
* overriding the _convertTo_ method over the ImageBitmapFormatUtils class
|
|
* hierarchy and overloading the _convertFrom_ methods over all sub-classes
|
|
* of ImageBitmapFormatUtils.
