Image processing apparatus, image processing method, and non-transitory computer-readable storage medium
View Patent ↗An image processing apparatus includes plural module creating units, plural wrapper creating units, an extracting unit, a calling unit, and an argument processing unit. The module creating units create processing modules that are obtained by instantiating different types of image processing classes by using functions. The wrapper creating units create wrappers that call the module creating units and that pass arguments specified in a pointer form to the module creating units. The extracting unit extracts, from image processing information, class names of the image processing classes corresponding to the individual processing modules and the arguments unique to the image processing classes. The calling unit converts the extracted class names and calls the wrapper creating units to which the converted class names are given. The argument processing unit stores the extracted arguments in an array, specifies an initial address of the array, and passes the initial address to the created wrappers.
