This function registers one of two available batch callback functions.

LPFNIG_BATCH_BEFORE_OPEN is called before a file is opened, allowing you to get the file name and correct some settings. For example, some multimedia formats and PDF files require you to get the file name before converting a page.
LPFNIG_BATCH_BEFORE_SAVE is called before an image file is saved, allowing you to correct an image before saving it. For example, you might want to rotate an image before saving it.
