This class implements only the basic functionality for an image like create, delete and convert. All image processing has to be implemented separately. The format of an image is described by the class CRxImageFormat. It consist of an image width, height, a pixel type and a data type. The pixel type defines the number and order of color channels, and the data type specifies the data type of each color channel. For example, the pixel type can be RGBA or BGRA and the data type may be unsigned byte (8bit) or unsigned short (16bit). The various pixel types available are defined in Rx::Interop::Runtime28::EPixelType::ID and the data types in Rx::Interop::Runtime28::EDataType::ID. Note that the values of the data type and pixel type defines are identical to the corresponding OpenGL IDs. All possible pixel and data types are represented by the TPixeltemplate structure. Specializations of this template structure cover all possible combinations of the defined pixel types and data types. The specialization names have the form TPixel_[PixelType]_[Data Type]. For example, the pixel structure for an RGBA unsigned char image is TPixel_RGBA_uc. The main advantage of using the TPixel_* typedefs to access the pixels of an image is, that you can write template functions that work on many different pixel types. The TPixel structure defines functions to access the various color channels that map to the correct element within a pixel. The pointer to the image data can be obtained with the function GetDataPtr(). Returns true if the data type of this image format is one of the custom (non primitive) data types. True if the data type is custom, false if not. Gets the total number of bytes allocated by images that are of this image format. The number of byte. Gets the pixel count. The pixel count.
